Game Testing Tutorial: How To Perform Game Testing ?

Video games hold a substantial share of the software market, creating a constant demand for innovation and complexity in the gaming industry.

Game development involves a collaborative effort among various professionals, including game designers, writers, visual artists, sound designers, and, crucially, game testers.

Therefore, it is important to be aware of the comprehensive process of game development and the pivotal role played by game testing in the entire process. Understanding the intricate phases of game development and the strategic implementation of testing strategies is essential for delivering a flawless gaming experience to users.

Game Development Process: Step-by-Step

Phase #1

Conceptualization The game development journey starts with conceptualizing the game, involving brainstorming to formulate the core idea, theme, and unique selling points.

Existing intellectual properties in various media or original concepts might serve as inspiration for this fundamental idea. This stage is critical for aligning the game’s vision across the development team and stakeholders.

Phase #2

Pre-Production In pre-production, detailed game design documents (GDDs) are prepared, outlining gameplay mechanics, narratives, character designs, and environment concepts.

This phase sees the creation of technical prototypes to validate gameplay ideas and mechanics.

Storyboards and concept art are developed to visually represent game narratives, environments, and characters, facilitating a shared understanding and vision among the creative team.

Phase #3

Production The production phase marks the bulk of game asset creation and coding. It involves the detailed development of game levels, character models, textures, animations, and game-specific logic.

Programming teams work on developing the game engine (if custom), integrating third-party libraries, and coding game mechanics, physics, AI behavior, and user interface elements.

This phase requires rigorous coordination between artists, designers, and programmers to ensure consistency and adherence to the game’s vision and design documents.

Phase #4

Post-Production Post-production focuses on refining the game through extensive QA testing. The game, now in its alpha state, is scrutinized for bugs, performance issues, and gameplay imbalances.

Feedback from alpha testing leads to adjustments and bug fixes, progressing the game to a beta state for wider testing, including compatibility testing and compliance checks with platform-specific standards.

This phase is iterative, with multiple testing cycles, feedback, and refinement until the game meets quality and compliance benchmarks for launch readiness.

Phases in game testing


Marketing Simultaneously with late development stages or post-production, the marketing phase ramps up to generate anticipation and demand. This includes creating promotional materials, engaging with media and influencers, and showcasing the game at industry expos.

Marketing strategies are tailored based on target demographics and platforms, focusing on highlighting the game’s features and unique aspects.

For indie developers or smaller studios, this phase might also involve direct community engagement through social media and crowdfunding platforms to build a supportive player base pre-launch.

What do you think the Game Testing Stage is intended to reveal?

The testing stage is a critical component of the game development process.

In addition, revealing potential bugs in the program—for example, in-game objects not running legitimately—. It should likewise check for irregularities in the fictional structure of the game, consistency (and culmination) of artwork, and additionally be testing the gameplay—is the game connecting with, too simple, or too hard, for instance?

Who is a Game Tester?

Game testers play a pivotal role in ensuring the quality of a game before its final release. They thoroughly test games on various platforms, including consoles and desktops, to identify bugs and defects. Without game testers, games could suffer from numerous issues, potentially damaging the reputation of the development company.

What are the requirements to Become a Game Tester

  • Attentive behavior
  • Understanding of video game console controllers
  • Awareness of SDLC
  • Good communication skills
  • Great writing skills
  • Primary computer programming aptitudes

Central Skills

  • Principles and perception
  • Analytical thinking
  • Knowledge of computer hardware parts
  • Investigating and exploring aptitudes
  • Versatility to tedious and redundant obligations

Typically, gaming companies don’t have a specific degree requirement. The skills are quite often tested at the interview. Still, education plays a significant role in game testing. The titans of the gaming industry prefer to hire employees with degrees in:

  • software development
  • computer programming
  • Computer science or some other technical field.

What does a Games Tester do?

Some of the key responsibilities of a game tester include the following:

  • Be repetitive and unpredictable to identify and break down potential issues.
  • Test different versions of games on various platforms.
  • Explore specific areas of the game and test all available options.
  • Play through different modes and characters to reveal glitches.
  • Report errors, spelling mistakes, and language issues.
  • Document bug reports in a bug-tracking system.
  • Understand the difference between reporting bugs and reporting features.
  • Test the game repeatedly in various conditions to ensure stability.
  • Analyze new game versions to check if previous bugs have been addressed.


The process involved in Game Testing

By far, we know that testing has an imperative function in Game development. A game is tested at the distinctive level of its development procedure. Usually, in the software engineering method, the Software test design document contains all the data about testing the product. However, game testing is not quite the same as testing the software.


There are numerous steps included other than test cases for a game, generally in light of the fact that almost all game testing is black box testing. The developers generally don’t test their own games, nor do they have time to test them completely, nor is it a wise idea to test games by themselves.

Before presenting their code for integration with the rest of the game or as third-party code for use by other game developers, game developers only test small portions of it.

6 Steps of the game testing are as follows:

  1. Plan and Outline the Test – Although quite a bit of this plan was done before in the programming test plan document, still with each new prototype of the game, this document should be returned to upgrade any adjustments in the test cases, specifications, and new setup support. The game tester ought to guarantee that no new issues are presented.
  2. Set up the Test – All the teams should upgrade their code, documents, tests, and test environment and regulate it with each other. The test development group should mark the bugs settled and the test time taken to confirm them.
  3. Play out the Test – Run the test suit once more. In the event that any bug is discovered, test around the error to ensure that the bug is real.
  4. Report the Outcomes – Complete insights about the bugs are reported.
  5. Repair the Bug – The game testing team engages in this step by uncovering the bug to the development team and giving direct testing to track the bug.
  6. Return to Stage 1 and Retest – A new build is delivered after one cycle.

The game test is performed in a structured way. Regardless of the size of the game and the time required for creating the game, all game testing should follow the fundamental structure.

Parts of Games That Undergo Testing

  • the menu and the menu functions
  • art (character model, terrain or world, texture, objects, crowd, etc.)
  • animation (the likeness and quality of the realism, movement, and frame rate)
  • music
  • audio and the sound effects (in connection with the facial animation, e.g., the animation series and lip sync)
  • any movie clips
  • camera (zoom in and out, cinematic view, replay)
  • title screens
  • game logic and flow
  • world/scene/level
  • the action properties
  • the player’s properties
  • the situation to advance to the subsequent level (what are the commands?)
  • the application of environmental objects
  • the object/event triggers
  • increasing levels of difficulty
  • the scoring
  • the AI logic (for both offensive play and defensive play; player positioning and movement)
  • statistics (pre-game and in-game, like high score and player statistics)
  • SFX – Special effect
  • NIS – Non-Interactive Sequence
  • the gamepad
  • the vibration/shock effect of the gamepad
  • the usability of the button functions
  • the application of multi-button actions (also known as button mashing)
  • the use of analog and digital mode
  • legal text
  • the game options (game start or menu selection, game pause, pause menu options, hints, and scrolling, such as driving by the accessible choices on the screen, so forth.)

Types of Game testing that need to be followed in the Testing Process

The game development cycle on all platforms has phases that are known as milestones. The milestones show that the game is at a specific level of development. The milestones, usually, are first playable, alpha phase, beta phase, gold phase, and post-release phase. The initial playable version is related to that of a demo version; here, the feel of the game is perceived and evaluated.

In a simplistic view, testing is recognizing bugs found in the game so the issue can be resolved. There are diverse types of tests that can be classified as black-box testing and clear-box testing. Their testing goal and general procedures are trivialities (e.g., test planning, test design, testing execution, regression testing, and bug reporting), yet their aim stresses various parts of the game. Let’s know what those techniques are:

Black Box Testing

It centers on the playability or functional parts of the game. For instance, testing the UI (e.g., the utilization of buttons and the selection menus), the “look and feel” (e.g., the designs and animation), and the real gameplay.

For Black Box testing, the game tester must know how to play the game, the utilization of the gamepad, and the game flow and the rules.

Blackbox Testing in Game testing

Clear Box Testing

It centers on the design and integration parts of the game software. For instance, the utilization of a database, pipelines, the integration and reconciliation of game segments like the AI engine, the rendering engine, sound, etc.

For Clear Box testing, the game tester must comprehend what coding is. The software tester employs a run-time troubleshooting environment, encourages the code or pieces of code with input, i.e., setting variables, data, and so forth, and interprets the test outcome.

Clear Box Testing in game testing

Functional Testing

 Its purpose is likely to be to recognize deviations from functional necessities. It comes down to driving through the game repeatedly to distinguish issues and the environments in which they can be rectified.

Functional Testing Diagram

Stress/Load Testing

When testing the games, it is fitting to create conditions that require a huge computational load. So, the game tester can check system execution in an unpleasant condition. With load testing, it is less demanding to see and fix possibly perilous code segments in time. Test for odd circumstances, like loading a game with no memory card, running the game for 48 hours, and checking how the game reacts.

Stress/Load Testing in Game Testing

Combinatorial Testing

 This type of testing is a process of experimental design that is applied for commercial software testing and to create test cases. Using combinatorial testing for game testing improves test performance efficiency, produces high-grade quality, decreases cost, and ensures reliable phase containment.

Every conceivable sequence of values of the parameters is incorporated into this test. Here the parameters are chosen from game elements, functions, events, character attributes, play options, settings, customization choices, and so forth.

combinatorial testing flow diagram

Compatibility Testing

 Much of the time, game programming is performed on laptops or PCs. Notwithstanding, numerous games can be intended for different devices: smartphones, game consoles, communicators, and so forth. Game development is performed on the test systems of these gadgets, yet they vary greatly from the original. In this way, later on, a few challenges may arise when beginning the game on the original gadget.

Plus, one should give careful consideration to the authorization of programming. In case of any aberrations, the game can be returned for correction, which takes additional time and a loss of funds. So, it is vital to check whether the game fulfills the necessities of the devices.

Feature Testing

 This testing is performed to confirm the smooth functioning of the features in the game. For covering discrete features, detailed test cases are more appropriate. Task-based experiments require a predominant level of detail. At the point when there is an assortment of features for various player statuses, test frameworks get convenient and beneficial.

Critical Path Test

Critical path testing is a procedure to recognize the critical paths in the game. This type of testing technique uncovers the conditions that cause disappointment.

Play Testing

Playtesting is the technique of game testers playing the game to break down non-useful features like fun variables, balance, difficulty levels, and so forth. Here, a selected team of testers plays the incomplete variants of the game to check the work process.

Limitation testing:

The games are regularly converted into the languages of the nations where they are assumed to be made available on the market. It happens that translators can’t give a totally exact interpretation, which would be completely reliable with the game events. Indeed, even if interpreted appropriately, it may not indicate the circumstances and abrade on the ears of the local speakers. Thus, after localization, it is helpful to test the game by natives of those nations where the ultimate game would be available.

Smoke Testing

 It is performed to test a new CD burn. The name Smoke Testing originates from the engineering lab testing new automobile engines. Before a new engine is taken for road testing, the engineers would just begin the engine and check whether it runs. In the event that smoke turns out from the motor, they would know promptly that a few sections don’t work appropriately.

Much like making another form, the game tester will essentially run the game; if it continues crashing, the tester will know a few sections are incorrect.

Regression Testing

 This type of game testing is done to retest the unaltered parts of the product. Here, test cases are re-checked to investigate whether the operation of the past elements of the application works fine and that new changes have not presented any new mistakes or vulnerabilities.

Multiplayer Testing

 Multiplayer testing is an entirely different beast in itself. Numerous players, all the while, associate with the game world, with game servers, with PC-controlled opponents, and with each other. Such huge numbers can turn out badly.

Furthermore, it regularly requires a complete team of game testers, various troublesome risk-based decisions to make, and the need to invest boundless amounts of time and energy in testing distinctive situations.

A comprehension of multiplayer game configuration and how to test proficiently as a group is required for this sort of game testing technique.

Sound Testing

 Sound testing is common in all products that make some sort of sound or play media. But games have a one of a kind feature that other software does not need to consider on a similar level. Game music must include the user in the game and upgrade the gameplay. Not only should the sound play without missing or shuttering components, but it ought to likewise add to the gameplay. This demands broad sound aptitude and a particular comprehension of game audio. Quite a specific master of domain awareness.

Ad-hoc Testing

 Ad-hoc testing is likewise, at times, alluded to as general testing. It is a less organized test. Ad hoc testing enables the game tester to investigate paths in view of their instinct. There are two types of ad hoc testing.

In the first place, there is free testing, which is a testing game with no arrangement or documentation. The other is direct testing, which is a solitary test performed spontaneously to answer a particular issue.

Test Flow Diagrams

Test flow diagrams are practiced to produce models depicting game behavior from the player’s point of view. Game testing involves examining the model along every potential path to examine unexpected game situations. A test Flow diagram is a formal way to test design. Since it is graphical in nature, it is simple to review, investigate, and give feedback on the test designs.

Complex test flow diagrams can interpret compact features, but typically, small test flow diagrams are preferable.

Test Trees

A test tree is a usability procedure for sorting out test cases that supports selecting an appropriate set of tests for a given arrangement of code changes. Test Tree enhances the general comprehension of complex game traits and deals with conceivably complicated functions, particularly when these functions connect with other game principles, elements, and functions.

The test tree is developed by disintegrating the element into a subset until the bottom nodes distinguish elements to utilize or spec to perform while game testing.

What is Bug Hunting?

Bug Hunting is a regular practice for some game testing companies worldwide, yet some test administrators wrongly feel they go Hunting when their game testers casually play with the application, keeping in mind the end goal of discovering “border case errors.”. Bug Hunts are Informal Testing activities; this should not be mixed up with playing with the system without a reason or goal.

  • Bug Hunts should be directed as team activities.
  • Bug Hunts are there so as to include non-testers and find less-ordinary bugs.
  • Bug Hunts require the system to be steady to be helpful.

Thus, to accomplish something (and not waste your time and efforts!!) on performing these Bug Hunts, you have to follow a particular procedure, execute planning and preparation activities, as well as observe and control the procedure all through its execution.

Types of Game Bugs in Game Testing


A crash bug is a severe issue that freezes or completely shuts down the game, often leading to a “Crash to Desktop” (CTD) scenario. Executing particular commands, loading into new areas, or coming across specific enemies are just a few examples of the in-game actions that can cause these bugs. Crashes are considered high-priority bugs, and game developers prioritize eliminating them to ensure a smooth gaming experience..

mobile app


General bugs are issues that do not halt game progression but still disrupt the gameplay experience. For example, a character disappearing unexpectedly, though not affecting the main storyline, can be classified as a general bug.

While these bugs may not be game-breaking, they can lead to player frustration and impact the game’s overall quality.


Minor bugs are small issues that have a minimal impact on gameplay but still need attention.

Examples include a character’s mouth not moving during dialogue or other subtle graphical glitches. Although minor bugs may not be prioritized, they contribute to the overall polish and professionalism of the game.


Severe bugs hinder the player’s progress without causing a game crash. These bugs can range from a disappearing character crucial for advancing a quest to a malfunctioning door preventing access to the next game area.

While not as critical as crash bugs, severe bugs are significant and must be addressed to maintain a coherent gaming experience.


Graphics bugs primarily involve issues with the visual elements of the game, including texture errors and map imperfections. An example of a graphics bug is an incorrect ground texture applied to a door.

Addressing graphics bugs is essential for maintaining the aesthetic appeal and immersion of the game.


Sound bugs relate to issues with in-game audio, such as incorrect timing or missing music cues. These bugs can occur anywhere in the game, from the main menu to the closing credits.

Sound bugs can disrupt the game’s overall atmosphere and must be corrected for a complete gaming experience.

Algorithm Bugs

Algorithm bugs occur at collision detection points within the game. Incorrectly placed walls or floors can cause players to leave the intended map boundaries, indicating a failure in collision detection.

Fixing algorithm bugs is crucial to prevent players from getting stuck or experiencing unintended interactions within the game environment.


Fatal bugs are game-breaking issues that prevent players from advancing further due to critical functionality failures.

An example is a jumping bug where a player needs to jump to progress, but the jumping mechanism fails, hindering progression. Fatal bugs demand immediate attention to ensure the game works correctly at all levels.

Configuration Trigger

Configuration trigger bugs occur when game settings have not been adequately tested, leading to failures.

These bugs can affect graphics and sound settings, potentially causing textures to disappear or altering audio configurations.

Configuration trigger bugs are uncommon in well-known games made by skilled programmers, but they can appear in online games that are downloadable.

How to Write a Bug Report Effectively?

A career as a computer games tester isn’t all fun and buffoonery. When you find a bug, you have to report it. Composing a game error report may look like a basic assignment. However, it is accompanied by a lot of duties. This is a correspondence from which other individuals will construct a plan of action with respect to game improvement. Those activities frequently incorporate submitting costly assets to settle the issue.

Here are a few tips for creating a bug report as a game tester. An adequate game bug report contains:

  • Title or Subject –

  1. Compile the critical elements of the issue.
  2. A basic overview of what, where, why, when, and how it is generated, featuring the most vital contemplations.
  3. Shows how extreme it is.
  4. Others utilize it to design a course of action; thus, it should be comprehended at once.
  • Classification

  1. A concise depiction of what, where, why, when, and how is generated with each and every detail.
  2. Here you ought to portray precisely “everything” about the issues.
  3. Classify it in such a manner that the reader can follow it entirely from the classification and comprehend totally what is going on.
  4. You may utilize industry-standard language to help precisely depict the issue.
  • Generation Steps –

  1. Well-ordered guide on the best way to replicate the issue.
  2. You ought to consider the individual heeding this guide has never observed the product and may even be new to the platform. Show them correctly what to do to reproduce the issue.
  3. Abstain from industry-standard language to guarantee the guide can be trailed by anybody.
  • Extra Information –

  1. Give additional helpful data.
  2. Assessment and theory, you can discuss how this bug may influence the player and conceivable inevitabilities created by the issue (such as bad customer reviews)
  3. Conclusions about different ways this may influence the game.

(Note: This segment is unnecessary in creating a report, though.)


What are the Opportunities as a Game Tester

Game-producing organizations, to achieve more profits, are always contracting computer game testers. So, finding the right source for the organization, whoever is hiring, is absolutely necessary. There are essentially three sorts of game testers. These are:

  1. Freelance Game Tester: The game testers who are freelancing are all around experienced and search out organizations that outsource forthcoming games to test the games. These testers are regularly the backbone of the game testing method. These game testers are usually contracted on a project-to-project basis. These testers are mostly used for black-box testing. Promptness, clarity, and communication in writing are critical attributes you should have.
  2. Full-Time Corporate Video Game Tester: There are potential people for being hired by big game-producing companies for full-time. For individuals who have a passion for playing games, no other activity can be as fascinating as this. Furthermore, the main capability required for this sort of employment is experience. No degrees or certificates are mandatory.
  3. Second-Party Testers: These game testers work on the testing team of a secondary or subsidiary organization under a bigger company. The second-party game testers can be either fully employed or contracted. Because of their close association with game developers, they frequently obtain access to more advanced tools. This usually results in a powerful focus on test cases and white-box testing. Most second-party testers are at least somewhat experienced in the game testing process.

Further, if you are looking forward to embracing video game testing as your profession, you must become more acquainted with the levels of game testing that are in charge of testing distinctive parts of the game. Quality assurance, Alpha testing, and Beta testing are the three primary kinds of game testing processes you will dependably need to begin with when you select this field as a profession. Alongside, there are other testing processes too.

Levels of Game Testing

  1. Alpha Testing

    • The initial testing phase is where the game is evaluated for major bugs.
    • Involves internal testing by the development team.
  2. Beta Testing

    • A select group of outside users test the game during pre-release testing.
    • Aims to identify potential issues and gather user feedback.
  3. Quality Assurance (QA) Testing

    • Comprehensive testing phase to ensure the game meets quality standards.
    • Conducted by experienced game testers.

What is Gold Testing or Post-Release Testing?

This is the testing stage, where the game is completely tested, has been launched to the general population has a totally finished product, and players have total access to the game.

Despite the fact that the game is completely completed, there is plenty of chances where a player can discover glitches or even game-crashing bugs. Under these circumstances, the developers need to discharge patches with a specific goal to fix them.

In the Gold testing level, every single crucial bug (hangs, crashes, and function disappointments) is resolved. 90% of every single significant bug (performance and functionality) is solved.

85% of every minor bug (system execution problems that hit a few users) is settled. Furthermore, release-level performance (i.e., 60-fps frame rate) is accomplished.

During its life cycle, if the game was delivered with even a couple of terrible bugs, it’s the ideal opportunity for an update or patch.

For each patch, the dev team must return to the whole list of bugs and consolidate some new, clean features. Every individual bug patch or polish element implies more testing (yet should be prepared).

Each new fix must be tested to detect whether it works with the base game and prior patch versions.

Mobile Game Testing

While many testing techniques overlap between different platforms, mobile game testing presents its own set of challenges and considerations. Ensuring a mobile game functions seamlessly, adheres to specific requirements, and provides an exceptional user experience is no small feat, especially given the diverse array of mobile configurations. 

The Significance of Mobile Game Performance

Mobile games captivate players with striking graphics, animations, and rich media. However, if the performance of a mobile game is lacking, these captivating elements become futile. Gamers expect a smooth, uninterrupted experience with consistent progress in gameplay. The importance of performance assessment cannot be overstated, as it directly impacts the player’s satisfaction and engagement.

Testing Navigation Flow, Usability, and User Experience

Emphasizing the genuine user experience, mobile game testing necessitates using actual devices rather than relying on emulators. Intricacies such as battery consumption, the impact of battery chargers, and potential intrusions significantly influence the overall user experience and entertainment value. Testing on real devices allows for a more accurate assessment of these factors.

Graphics Execution and Early-Stage Performance Tests

The graphics execution of a mobile game is intricately linked to user experience. While striking graphics and animations enhance the visual appeal, their effectiveness diminishes if the game’s performance lags. To address potential performance blockages, it is essential to conduct performance tests during the early stages of game development. Identifying and resolving performance issues early in the development process ensures a streamlined gaming experience.

Three Basic Phases of Mobile Game Testing

  • Device Performance Testing
  1. Start-Up of Game: The initial screen should appear within 1-2 seconds of pressing the game icon. b. Memory Consumption: Adding functionalities increases memory usage, requiring careful management. c. Software/Hardware Variation: Test the game on various devices with different RAM and processor specifications. d. Battery Time: Continuous gameplay should not excessively drain the battery or cause the device to overheat. e. App in Background: Resuming the game from the background should retain its previous state. f. Usage with Other Apps: The game should run seamlessly when used simultaneously with other applications.
  • Network Performance Testing
  1. Jitters: Networks using packet switches cause address delays in data transmission. b. Network Speed: Test the game on 2G, 3G, and 4G or 5G networks, including mobile networks and Wi-Fi.
  • Testing API/Server Performance
  1. API Calls: Limit the number of calls from the game to ensure optimal performance. b. Information To and From Server: Efficiently handle data transmission between the game and server. c. Server Down Time: Implement failover database servers to ensure continuous availability in case of server issues.



Effective game testing is a structured and comprehensive process that involves various types of testing techniques. From functional testing to stress testing and bug hunting, each step is crucial in ensuring a flawless gaming experience for users. Understanding the components of games that undergo testing, the types of testing involved, and the techniques used are essential for game testers and developers to deliver high-quality games to the market. The iterative nature of the testing process ensures continuous improvement and refinement, ultimately contributing to the success of the gaming industry.

Testing a Game Like PUBG: What to Consider?

Player Unknown Battlegrounds aka PUBG is everywhere nowadays. Millions of users are playing the game even while you are reading this blog.

It’s a huge online game and the company is frequently introducing features to make the battle royale game more interesting.
For these obvious reasons, Game Testing is absolutely necessary for the survival and continued success of the game.
The main purpose of game testing is to ensure that the game is appropriate. There is a number of predefined features and requirements that are tested in an application to ensure that an application is up to the mark.
However, when it comes to game testing such as PUBG then it is essential to be precise and follow up every single detail.
Difference between Regular Testing and Mobile Game Testing
In order to understand the whole concept of mobile game testing such as PUBG, one must understand how it differs from regular testing.

The first and foremost difference between the both is strategies and impact of software. The regular mobile application, have a limited number of features and users have to go through them only.
But when it comes to mobile games, they can be unpredictable. The whole game will depend on what route a user is following that can be different from the one tested.
This behavior of a user impacts the game on a huge level. However, the major point to keep in mind is to ensure that the game is easy to interact.
In addition to this, you need to work on the complex part where user influence can take part. However, the game like PUBG works on player’s behavior only. It will depend on the course a player is moving toward that will change the whole concept.
Hence, you need to be more careful with it.
Different Part to Test in PUBG
When it comes to mobile phone games, you need to set things as per the priorities. Especially, with PUBG where there are so many feature to cover. You can prioritize them in order to have a proper game test. Here is a list of features to add on to your priority list.
1. Graphics Performance
You need to ensure that all the graphics are up to the mark in your game. The mobile games similar to PUBG will have high graphics and since it works in real time, it might be difficult to be abreast with the environment and every single player. Hence, you need to ensure that it is smooth and is extremely responsive. A game with graphics issue can be slow or might crashes a lot.
In order to test the graphics of a game, stress testing technique is used. Hence, one can know the actual speed or performance of a game in mobile phones.
There are several tools that can be used to check on stress or graphics of a game. This will give you an idea about the flaws of a game and also analyze its working in the real environment. It will also give you an idea of the traffic workload and how it will work under extreme stress.
2. Social Media Integration
Another the essential feature of a mobile game is its connection to social media accounts. This feature is covered up in different gaming application including PUBG.

If anything, it is for the success of that particular game only in this digital world. Every single thing in the current world depends on social media.
Hence, it becomes essential to be updated with social media to ensure that a maximum of people is connected with each other.
In addition to this, it can be taken up as a marketing strategy as well. There are so many games such as Candy Crush Saga that is popular due to the integrated form of social media. Hence, this is one of the essential features to test while checking up on the list.
3. Game functionality and User Interface
Another of the essential feature to keep in mind is the UI of the game. People are attracted to a particular game due to its amazing User Interface. Hence, it is essential to keep in the priority list.
Also, the functionality and how it is reacting when a user changes its course is another factor that will set up mobile phone priority.
Is the resolution of a game perfectly?
Do you think that games will be satisfied with these features?
Are all the features to mark irrespective of player’s behavior?
These are some of the crucial aspects to keep in mind when it comes to the game like PUBG.
Also, one must know what the function and structure represent to check on the screen orientation and layout. It is the not to be missed part of this whole checklist.
4. Multiplayer
PUBG is a multiplayer game that works together in a real-time environment. Here players compete with other real players on a single platform.
app testing
They can be their family or friends making a game success. However, if the real-time part of this whole setup is not working up then you can know the disaster it will have for a game.
Hence, multiplayer functionality must be kept in mind if you are testing something similar to PUBG.
The worst part about multiplayer work is that is can be a daunting task to get the hang of it. There is simply so much to cover up with you is testing an application for more than one player at a time.
The same interference in real-time for players setup is a challenge that one has to go through. On top of that, the data is exchanged between a server and a device that makes it even more challenging.
In such case, you need to work on the server to ensure that it can work for the whole setup without a hitch.
Different Type of Testing Used for Game
1. Sound Testing
PUBG have a feature where a team of players working against others can easily communicate through messages and voice.
On top of that, the gunshot, walking, running, etc. type of sounds are amazingly instilled in the application.
When it comes to checking on these features, then it can be difficult. Hence, one must have an idea about file loading, distortion errors, analyzing CC profilers, color commentary, etc.
2. Compliance or Conformance Testing
Yes, this is one of the most essential types of testing when it comes to games. It requires a proper workflow in terms of compliance.
Also, there are a few things that are prohibited by stores that make it essential to keep a track of them.
Hence, while performing this testing, one has to keep an eye for the content that might be against guidelines. It is to ensure that any inappropriate content is not affecting the rating of a website.
3. Functional Testing
This type of testing is mainly to understand the functions of the whole game. It will give an insight on different functions on the generic level of a game.
It will cover the graphics, interface, and features of an application. There are several issues that can be found through this testing such as stability, mechanic, user-friendly, user interface, etc.
4. Soak Testing
In this testing, one can come out with a mode that is used in operation of a game. It will give a running of a game in the prolonged period.
This basically explains the rounding errors or memory leak type of errors in an application that can end up with crashing the whole game.
5. Performance Testing
It is one of the most essential types of testing that is used in a game. It will give an insight into the optimization of the game in terms of speed.
Also, one can work on the performance of a game to get the response time, transaction time, network coverage, peak load performance, low battery, memory leakage, longevity, application download, low memory, etc.
In addition to this, it will also cover network connectivity, memory and processor constraints, graphics consumption, etc.
Adaptive Technology Assistive Gaming
This type of testing technique will include the whole accessibility format of a game. It is mainly due to the features that will have several features added to it such as blurred vision, low vision, blindness, etc.
These disabilities are added in the list with the other such as cognitive, hearing, speech, colour and even mobility impairments.
In such modes, there are many games that have to ensure to add features to the people that are challenged in terms of visual. Hence, if a game has such features it is essential for a tester to watch out for testing methods for these such as visual data, colour, gaming dimensions, etc.
Game Testing Risks
Yes, with work comes challenges and things that we must steer clear off. Here, are few of the topmost risks:

  • No player-centric design
  • No compelling expiring that might be difficult for gamers to play
  • Missing out of gameplay features
  • No fast-paced, competitive and unique part of the game
  • Over budget gaming development
  • Failure concerning critical bugs, technical issues, poor video, music sound an even broken features
  • Simple aesthetic design.

12 Things Your Competitors Can Teach You about Beta Testing

These days there is a lot of competition in the market. Every business wants to prove that they are the best and have the edge over other businesses. As everybody’s technology and strategies are improving day by day, there is a huge opportunity to learn from the others businesses too. Our biggest learning source comes from our rivals. They can teach us many things which you can easily grasp and improve yourself.

User Acceptance Test (UAT) is a software testing procedure executed in a real-world scenario. UAT has two types, Alpha, and Beta testing. Alpha testing takes place in the company whereas beta testing is field testing. The software is tested in real-world working conditions which takes place at the customer’s site.

12 Things You Can Learn From Your Competitors about Beta Testing

These are the followings practices which can be taught by other competitors about beta testing.

  • The important thing that you can learn from your competitors is how they proceed with the beta testing and how they strategize their every action. They prepared several instructions before proceeding with the beta testing. Proper project planning should be written down and agreed upon by the other fellow mates. The objective of the beta testing and how you’re going to achieve that goal should be clear. After you’ve prepared a proper plan then follow these steps to ensure the simplicity in your work. Also, the quantitative goal and business metrics must be selected in order to make a process smoother.


  • Selecting and recruiting a proper team of a beta tester is also a major role that should be kept in your mind. If you’ve ever looked at the team of other competitors who include professional beta testers, they are able to achieve their work more easily. You can also gather a team of professionals with experience in the beta testing. Their opinions and aspects would be totally different which will provide various working conditions which can be used for the beta testing procedure. Your team for beta testing won’t be of good use if there would be no opinions from the people who are experienced.


  • If you want to improve your structure of software or modifying it, you can learn how the other competitors take feedback from their users. By taking the proper feedback from their users they alter every single of the bugs or error which shows up during the beta testing procedure. You can also improve your software by taking feedbacks from your user when they start using the beta software. Thus if you gather the feedback more quickly, the better your approach would become. Most of the other companies have the habits to take a frequent feedback from their users to ensure everything’s working well. The feedback can be in the form of bugs report, quotes, suggestions or surveys.


  • Learn the major tools which are being used by the other software testing companies and try to understand the concepts of different tools which are used in the beta testing procedure. Thus it would be a great thing to learn from the other top companies and follow their footsteps. Try using different tools and adapt them. You can always learn new methods from the other competitors. Every company has their own methods and ways to proceed with the beta testing at a customer’s Make sure that you learn and improve your beta testing skills by using various tester tools which normally other companies are expert in using.


  • Make sure that you are running every aspect of beta testing. As you’ve already planned the layout on how you’re going to test the product.

6 Must-Do Things When You Perform Game Testing

Just like normal software, it’s necessary to test games as well to ensure that they work as intended before they reach the audience. There is no defined strategy for game testing as each game and the platforms used differ. While performing game testing, all aspects of the game including functionality, usability, multi-player functionality, regression, endurance, compatibility, performance, content, hardware, recovery and localization need to be tested. The basic game testing process is similar to software test cycle.
The basic steps of game testing include:
Gathering requirements
The testers need to have a detailed understanding of gaming requirements such as storyboard, game structure, game features, characters, concept, rules, game points and levels. It helps the testers to come up with an effective testing strategy.
Devising a game testing strategy
The game testing strategy must include the testing timeline, testers, number of testing cycles, in-scope i.e. what needs to be tested, out-scope i.e. what’s not tested, types of testing to be performed, testing for risks, service level agreements, risks and mitigation, defect finding process, reporting Process etc.  Also, it’s important to test the hardware components such as hardware components such as Joy stick, Console, Wi-Fi devices etc. that are not usually the part of game testing environment.
Creation of test cases
The testers must design both positive and negative test cases. Critical path testing, exception path testing, boundary value analysis, equivalence partitioning, error guessing etc. are some effective testing that can be adopted to design the test cases.
Executing game test cases
This helps to identify more defects in a particular gaming environment and hardware configuration. Also, performing the alpha and beta testing and the testing of the game for specific age groups helps to enhance the game’s quality. Another type of testing that mustn’t be ignored when it comes to games is content testing. This helps to ensure that the content of the game is right for the viewers and is understandable.
Recording of test results
The aftermath of the game testing performed must be recorded. This helps the testers to understand the behaviour of errors being made and improve them.
Categorizing the defects
All the defects that have been identified must be recorded and categorized based on priority. This helps the developers to easily rework the errors.
After game testing is performed and the changes have been made, the game is then sent to the clients for feedback. It is then further improved based on the feedback before delivering to markets for the audience to enjoy a hassle-free gaming experience.

The What, Why and How of Mobile Game Testing [Overview]

When hearing about mobile game testing, one of the immediate questions that come to your mind is, why is there such a distinction And how is mobile game testing different from a regular mobile application testing? This article will help answer some of these questions that you may have.
What is Game Testing?
Game testing is similar to a software testing process and is done for quality control of video games. The primary objective behind game testing is the detection and documentation of bugs in the game codes. A game tester needs key skills such as programming expertise, advanced problem-solving ability, a keen eye for detail and patience.
Why is it so Important?
Right from the point your prototype video game is out after production, the testing phase begins. The game developer’s role becomes reliant upon the requirements and suggestions supplied by the game tester. The job responsibilities for a game tester are mainly divided into two sections: Firstly, detection and reporting of the game defects, and then helping with its analysis and verification.
A gamer downloads your game on the first impression that it gives- either the description was so catchy or maybe there was a new irresistible element or a new way of approach being offered in your game. Once the gamer has decided to give it a try, an observant critic is also shaped within. If your game doesn’t keep the gamers spirits high as promised, it is definitely going to get thrown out. Besides uninstalling, maybe the user could give you negative ratings and reviews. So it is important that your game is tested rigorously.
With increasing number of mobile games being developed all over the world, the standards are going up continuously. There is no limit to the choices that a gamer can make. In order to compete and thrive in the market, you should take up the struggle of delivering the best possible quality products.
A good mobile game tester should also be a good mobile game player. They can use their experience in gaming to envision the perspective of other players, thus being able to rate the game better, and decide what’s best for its success.

What is the Difference between Game Testing and a Regular Application Testing?
You can play a game and find out bugs, even if you are not an expert, unlike app testing but to reign over the industry, professional knowledge is inevitable. Untrained testers are just part of testing the alpha and beta releases and open user testing, which supplements the end phase testing. A game tester should master the discipline of testing in general, but at the same time should also have expertise in game testing as a separate stream.
Though there are similarities in the methods and procedures of mobile game and mobile app testing, the motives and goals behind testing both are entirely different. Mobile game testing must include both manual and automation processes. General categorization will involve the black and white box testing.
Black box testing: Black box testing is done to ensure the quality of functional aspects of the game. In this type of testing, there is no attempt to look into the internal structural elements of the game. For black box testing in games, major areas of focus under testing includes GUI, audio functionality, animations, realistic effects etc.
White box testing: White box testing is strictly the opposite of black box testing in terms of its role. The method here is used to test the appropriateness and efficiency of the internal structural elements of the game. The importance lies on testing the architectural and integration features.
Mobile Game Testing- Various Methods
The different spheres of game testing are very similar to that of application testing. Those notable in the field of game testing are the following.
Functional testing: This is undoubtedly the most common form of game testing performed. Mostly done manually, it requires you to play the game during the test process. A game tester should have a sound knowledge of game programming and game environments in order to discover the discrepancies associated with the performance. Automation is also a viable possibility in several areas of functional testing.
Performance testing: Testing tools are used in performance testing. As the name suggests, this test is carried out to ensure quality game performance. During performance testing, the key attributes tested are – speed, scalability, stability and reliability. Performance testing is usually divided into four- load testing, stress testing, soak testing and spike testing of which, load testing is more prominent for testing mobile games.
Game performance varies with the device interfaces in use. An extensive testing including all the popular mobile devices is important in confirming the success of your game among a wider audience. Poorly performing games doesn’t guarantee fluid experience for its users. Performance testing encompasses multiplayer testing, memory consumption testing, maximum load support testing etc. These tests can be automated with the help of test script simulations or real-world content.
Compatibility testing: Compatibility testing is done to test whether the game is compatible with the various device platforms and configurations. It is commonly done in two sections during the early and late beta time period of the game to reduce cost. Nevertheless, it is advised that you carry out the testing during the whole phases of development since this provides better insights into the compatibility issues that have crept within, if any.
Localization testing: This kind of testing is only applicable if your games are developed targeting the global market or other language users. Text in games such as titles, instructions etc. should be translated, reviewed and corrected by employing localized testers who have mastery over the local language where it is to be released. These tests are also done automatically but testers should be employed to proofread to ensure the accuracy and quality of the text.
Regression testing: Every time you make a change in your mobile game, another type of testing needs to be done, namely regression testing. Regression testing is really important where a client-server interaction is present and continuous changes are put into effect. Developers must confirm that these changes don’t interfere with the normal working of the game. Regression tests are only done as an automated testing.

Some key areas to focus in game testing
During game testing you must make sure that the following areas are covered under your testing methods.
User Interface and Functionality: User interface testing ensures user –friendliness of your mobile game and the functionality testing tests whether your game fulfills the functionality specifications.
An appealing user interface is the first thing any mobile game should focus on since it is from this that the user gets the first impression about the game. It directly determines the success of your game. Even when your game upholds a great idea with effective responses, if it fails to deliver a clean and sturdy UI, the game will have a hard time hitting the mark.

  • Testing user interface includes checking
  • colors and backgrounds
  • menu structure and functions
  • screen orientation and screen resolution adjustments
  • proper instruction execution
  • usability
  • system navigation such as loading time and display sequences
  • animations and audio elements apt for your game
  • textual matter such as instructions and dialogue messages
  • font and alignment errors etc.

The functionality testing checks from elements such as the ones you find in the pop-down menus, confirmation messages and other functions such as time-out and sorting.
Graphics Performance: Graphics testing should bound testing game performance over a large number of real devices and noting the respective abnormalities. Battery consumption needs to be optimum over long hours and game responses should be satisfactory under heavy loads across all the different devices. This test helps to determine your potential game responses when working on a real device platform.
Usability, User Experience and Fun-factor: Usability and user experience testing are common to all kinds of application testing. What makes game testing different is the fun-factor testing. The motive behind playing game is purely for entertainment reasons. Therefore your games are expected to provide entertainment along with great user experience.
Assessing fun-factor needs some aesthetic sense and critical thinking. Entertainment is delivered only if all other aspects of the game work together correctly and it takes good effort to accomplish. A loading lag or frequent interruptions can badly affect the user’s experience.
Multi-Player Games: Nowadays, numerous games are multi-player oriented and includes features that promote team play. These teams may include real or virtual characters. Testing multi-player features are more challenging than testing single-player elements. In multi-player games, connectivity to the server and synchronization of game status are two new important areas that need to be addressed. There are a number of issues that demands attention with respect to multi-player gaming.
Social Integrations: This encompasses the various types of testing specifically done to games that offer social integration. Social integration is included to provide users with rich gaming experiences. It allows new features such as game status updates, friend invitations, premium gift sharing etc. Testing involves ensuring problem-free working of these features.
Security Risks: Third party codes are often used to support the general functions in a game during mobile game development to reduce the work load. But these codes can compromise security and allow data breach. Identification and rectification of open source component vulnerabilities are necessary for a risk-free gaming experience.
Maintaining Balance: Creating a balance throughout the entire game is unavoidable for its logical integrity. There should be balance in the different levels of the game. For example, levels should be arranged in increasing order of difficulty or there should be opportunities to unlock more powers in the upper levels. Ensuring balance requires knowledge of the entire game design.
Levels in the Game: In game level testing, each of the levels in your game is tested for any working problem. This is a complex and time-consuming process especially if the world is vast and 3 dimensional. Complexity increases proportionately with increase in the levels. There are automation tools available where tester bots are allowed to roam randomly throughout the world and thereby any world level defects are detected.
AI for Game Opponents: Artificial intelligence refers to the computer-controlled counterparts in your games. This is a complicated task and it requires the tester to understand what activates the system for a particular response. Chess is a typical example where an artificially intelligent counterpart is employed.
Physics Engines: Real-time physics engines are widely used in games, especially in 3-dimensional video games to simulate the physical phenomenon, interactions and dynamics of physical entities. The simulation needs to be only approximate which gives a perceptually real representation of an object or a movement rather than being physically accurate. A bullet shot or a combat should show the likeness of a real world happening.

Nowadays, soft body dynamics and fluid dynamics are used in games to give effect to clothes, leaves, fluid motion and the like apart from using rigid body dynamics for objects like rocks and building. Testers working with physics engines must have a basic idea of the physical attributes of different objects and the various dynamics in the physical world.

Realistic Games: With the progress in various mobile device performance delivered by high power processors and better quality graphics hardware, video games now tends towards being more of real-world representations. Racing games features models of original cars and there are other games where characters are more life-like with minute details given to even the movement of hair.

Apart from graphics quality, realism is achieved by providing the right perceptional approximations, cause and effect relationship, right emotional expressions to characters etc.

Testing virtual reality requires hard work and subject knowledge. An understanding of the respective field is important for the game tester, for e.g. weapon techniques, component specific operations, vehicle controls, animal behaviors and instincts etc.

Mobile gaming testing is a vast area, and as mobile gaming becomes more mainstream, proper testing can make or break your fortune. So, try to find the right game testers for your mobile gaming app.
