This initial phase sets the foundation for a software’s development lifecycle, highlighting its pivotal role in successfully realizing robust, user-centric software solutions.

Introduction to Requirements Elicitation

Definition of Requirements Elicitation

Requirements Elicitation is a foundational process in software engineering where stakeholders’ needs, desires, and constraints for a new or altered system are identified, gathered, and understood.

It involves direct interaction with stakeholders, including users, customers, and others involved in the project, to capture detailed system requirements.

This process is not merely about asking what the stakeholders want but involves a deep investigation to uncover and document explicit, implicit, tacit, and future needs.

The goal is to create a comprehensive and accurate requirements document that serves as a cornerstone for all subsequent stages of software development.

Importance in Software Engineering

Requirement elicitation holds paramount importance in software engineering for several reasons:

  • Project Foundation: It sets the foundation for the project by ensuring that the software development team fully understands what needs to be built. This clarity is crucial for defining project scope and preventing scope creep.
  • Stakeholder Satisfaction: By actively involving stakeholders in the elicitation process, it ensures that the final product meets or exceeds their expectations, leading to higher satisfaction and acceptance.
  • Risk Mitigation: Proper elicitation helps identify potential issues and misunderstandings early in the project lifecycle, reducing the risk of project failure due to unmet requirements.
  • Cost Efficiency: Understanding requirements upfront helps in accurate project estimation and planning, reducing the likelihood of costly reworks and delays that stem from incomplete or misunderstood requirements.
  • Quality Enhancement: Detailed and well-understood requirements contribute to better design, development, and testing processes, leading to a higher quality product.

Overview of the Requirements Elicitation Process

The requirements elicitation process typically involves several key phases:

  1. Preparation: Before interacting with stakeholders, it’s crucial to identify who they are, understand their background, and prepare the right set of tools and techniques to facilitate effective elicitation.
  2. Elicitation Techniques Application: Employ techniques tailored to the project and stakeholders involved. Common methods include interviews, focus groups, surveys, document analysis, observation, and prototyping. Each technique has its strengths and is chosen based on the specific context and requirements of the project.
  3. Requirements Documentation: The information gathered from stakeholders is documented in a structured format. This could be in the form of user stories, use cases, requirement specifications, or models. The choice of documentation often depends on the project methodology (Agile, Waterfall, etc.) and the complexity of the system being developed.
  4. Analysis and Negotiation: Analyzing the documented requirements to identify conflicts, redundancies, and gaps. This phase often involves negotiating with stakeholders to prioritize requirements and resolve conflicts arising from differing needs or constraints.
  5. Validation and Verification: Ensuring the requirements document is complete, consistent, and acceptable to all stakeholders. This includes validating that the requirements align with business objectives and verifying that they are feasible within technical, time, and budget constraints.
  6. Baseline and Maintenance: Once validated, the requirements document is often baselined as a reference point for future project activities. Requirements management continues throughout the project, accommodating changes and refinements as the project evolves.

Understanding the Basics

Requirements Elicitation is a critical phase in software development where the stakeholders’ needs, desires, and constraints are identified and documented to guide the design and development of a new or modified system. This process ensures that the software development team fully understands what must be built to meet stakeholders’ expectations effectively. It involves various activities such as interviews, surveys, workshops, and analysis to capture the said and unsaid needs of the users.

Types of Requirements

  1. Functional Requirements:
    • Definition: Specify what the system should do. They describe the interactions between the system and its environment, independent of the implementation.
    • Examples: User login process, data processing logic, and report generation capabilities.
  2. Non-Functional Requirements:
    • Definition: Outline the quality attributes or constraints the system must exhibit. They are not about specific behaviors but how the system performs under certain conditions or constraints.
    • Examples: Performance metrics (response time, throughput), security standards, usability, scalability, and compatibility.
  3. System Requirements:
    • Definition: Detailed specifications describing the software system’s functions, features, and constraints. These can be further divided into software and hardware requirements.
    • Examples: Hardware specifications (CPU, memory, disk space), software dependencies (operating systems, middleware), system integrations, and system behaviors.
  4. User Requirements:
    • Definition: Express the needs and desires of the end-users in terms of tasks they need to perform with the system, often documented in natural language or through use cases.
    • Examples: Ability to export data into various formats, user-friendly interfaces for non-technical users, and custom notification settings.

Stakeholders in Requirements Elicitation

Stakeholders are individuals or groups with an interest in the outcome of the project.

They can have an impact on or have an impact on the project’s success. In requirement elicitation, stakeholders typically include:

  2. Define Characters: Create personas for the users involved in the scenarios to add depth to the narrative and ensure the system’s design addresses their specific needs.
  3. Sketch the Storyboard: Draw or use digital tools to create a sequence of panels that depict the user’s journey, including interactions with the system, decision points, and outcomes.
  4. Annotate and Describe: Add annotations to the storyboard to clarify actions, motivations, system responses, and any specific requirements or constraints the scenario highlights.
  5. Review and Iterate: Share the storyboard with stakeholders for feedback and use their input to refine the scenarios, requirements, and design concepts.

Challenges:

  • Time and Skill: Creating effective storyboards can be time-consuming and requires a certain level of artistic skill or specialized tools.
  • Complexity Management: Managing and integrating numerous storyboards can be challenging for complex systems with multiple user roles and interactions.

Technique #6: Ethnography

Ethnography, within the realm of requirements elicitation

Ethnography, within the realm of requirements elicitation, refers to a qualitative research approach that deeply immerses researchers in the natural environment of their subjects to observe and understand their behaviors, practices, and interactions with technology.

This anthropological method is adapted to software development to gain insights into user needs, experiences, and the context in which a system will operate. It involves studying users in their work or life settings rather than in artificial environments or laboratory conditions.

Application for Requirements Elicitation:

  • Direct Observation: Researchers observe users going about their daily tasks, noting how they interact with existing systems and identifying pain points, inefficiencies, and unmet needs that the new system could address.
  • Participatory Observation: Sometimes, researchers actively participate in the environment they are studying to get a firsthand understanding of the user experience and the challenges users face.
  • Interviews and Informal Conversations: Engaging with users in their natural settings allows researchers to gather nuanced insights through casual conversations, in-depth interviews, and group discussions.
  • Artifact Collection: Gathering physical or digital artifacts that users interact with (e.g., documents, tools, software) provides additional context about their tasks and workflows.

Benefits:

  • Deep Contextual Understanding: Ethnography offers an in-depth understanding of the user’s work environment, social interactions, and the cultural factors that influence their interactions with technology.
  • User-Centered Design Insights: The rich, qualitative data collected can inform a more user-centered design process, ensuring that the system meets real user needs and fits seamlessly into their existing workflows.
  • Identification of Tacit Needs: This approach can uncover implicit needs and requirements that users themselves might not be consciously aware of or able to articulate in a traditional elicitation setting.

Challenges:

  • Time and Resource Intensity: Ethnographic studies can be time-consuming and resource-intensive, requiring extended periods of observation and analysis.
  • Interpretation and Bias: The qualitative nature of the data collected requires careful interpretation, and researchers must be mindful of their own biases in observing and reporting on user behavior.

Integration with Software Development:

Ethnography’s insights are particularly valuable in the early stages of software development, helping to define the problem space and identify user requirements.

The findings from ethnographic research can feed into the creation of personas, user stories, and use cases, guiding the design and development of the system.

When combined with other requirements elicitation techniques, such as interviews, surveys, and workshops, ethnography can provide a comprehensive understanding of user needs and the context within which the system will be used.

Technique #7: Use Case Approach

Use Case Approach:

The Use Case Approach in requirements elicitation is a method that focuses on identifying and defining the interactions between a user (or “actor”) and a system to achieve specific goals.

This approach helps in capturing functional requirements by describing how the system should behave from the user’s perspective, providing a clear and concise way to communicate system behavior to both technical and non-technical stakeholders.

It plays a crucial role in the early phases of software development, ensuring that the software functionality aligns with user needs and expectations.

Key Components of the Use Case Approach:

  • Actors: Represents the users or other systems interacting with the subject system. Actors are external entities that initiate an interaction with the system to accomplish a goal.
  • Use Cases: Describes a sequence of actions the system performs that yields an observable value result to an actor. A use case is a specific situation or scenario under which the system interacts with its environment.
  • Scenarios: Detailed narratives or sequences of events, including main, alternative, and exceptional flows, illustrating how actors interact with the system across different use cases.

Process and Implementation:

  1. Identify Actors: Identify all potential system users and other systems that might interact with it. This includes direct users, indirect users, and external systems.
  2. Define Use Cases: For each actor, define the specific interactions they have with the system. This includes the main objectives or tasks the actor wants to accomplish using the system.
  3. Write Scenarios: For each use case, write detailed scenarios that describe the steps the actor and the system take to achieve the goal. This includes the ideal path (main scenario) and variations (alternative and exception scenarios).
  4. Prioritize Use Cases: Prioritize the use cases based on factors such as business value, frequency of use, and complexity. This helps focus development efforts on the most critical aspects of the system.
  5. Validation and Refinement: Validate the use cases and scenarios with stakeholders to ensure they accurately represent user requirements. Refine the use cases based on feedback.

Benefits of the Use Case Approach:

  • User-Centric: Focuses on user interactions, ensuring the system meets the actual needs and expectations of its users.
  • Clear Communication: Provides a common language for discussing system requirements among stakeholders, including non-technical users.
  • Identification of Functional Requirements: Helps in systematically identifying all the functional requirements of a system through the exploration of various user interactions.
  • Facilitates Testing and Validation: Use cases can be directly used as a basis for developing test cases and validation criteria.

Challenges:

  • Complexity in Large Systems: Managing and maintaining the use cases can become challenging for systems with many use cases.
  • Overlooking Non-Functional Requirements: While excellent for capturing functional requirements, the use case approach may overlook non-functional requirements unless explicitly addressed.

The Use Case Approach in requirements elicitation is a powerful tool for understanding and documenting how a system should interact with its users. Focusing on the user’s goals and describing system interactions from the user’s perspective ensures that the developed system can perform its intended functions effectively and meet user expectations.

Technique #7: CRC (Class Responsibility Collaboration) in requirements elicitation

CRC (Class-Responsibility-Collaborator)

CRC (Class-Responsibility-Collaborator) cards are a brainstorming tool used in the design and development phases of software engineering, particularly useful in object-oriented programming for identifying and organizing classes, their responsibilities, and their collaborations.

Although not traditionally framed within the requirements elicitation phase, CRC cards can play a significant role in understanding and refining requirements by fostering a clear understanding of how different parts of the system interact and what their purposes are.

Here’s how CRC cards can be beneficial in requirement elicitation:

Understanding CRC Cards

  • Class: Represents a category or type of object within the system.
  • Responsibility: Outlines what the class knows and does (i.e., its attributes and methods).
  • Collaboration: Indicates how the class interacts with other classes (who the class works with to fulfill its responsibilities).

Role in Requirements Elicitation

  1. Clarifying System Structure: By identifying classes and their interactions early on, stakeholders can gain a clearer understanding of the system’s proposed structure and functionalities.
  2. Facilitating Discussion: The simplicity of CRC cards makes them excellent tools for facilitating discussions among developers, analysts, and stakeholders. They can help in uncovering hidden requirements and ensuring a common understanding.
  3. Identifying Key Components: Through the process of defining classes and their responsibilities, key components of the system that are necessary to meet the requirements can be identified.
  4. Enhancing Collaboration: The collaborative aspect of CRC cards encourages stakeholders to actively participate in the development process, promoting a deeper engagement and understanding of the system requirements.
  5. Iterative Refinement: CRC cards can be easily updated, allowing for iterative refinement of classes and their relationships as more information is gathered or requirements change.

Implementing CRC Cards in Requirements Elicitation

  • Workshops: Organize CRC card sessions with stakeholders to collaboratively define and refine system components.
  • Visualization: Use CRC cards to create visual representations of the system architecture and how different parts interact, aiding in the identification of potential issues or requirements not yet considered.
  • Documentation: Transition the insights gained from CRC card sessions into formal requirements documentation, ensuring that the system’s design aligns with stakeholder needs.

What is CMMI? (Capability Maturity Model Integration): How To Achieve It?

What is CMMI?

CMMI is a process improvement framework that provides organizations with guidelines for developing and refining their processes to improve performance, quality, and efficiency. It offers a structured approach to process improvement by defining a set of best practices that organizations can adopt and tailor to their specific needs.

Established by the Software Engineering Institute at Carnegie Mellon University, it was developed as a process enhancement tool for software development. It is now managed by the CMMI Institute.

CMMI can be applied to product and service development, service establishment, management, and delivery. It helps guide process improvement across a project, division, or entire organization.

CMMI models are used to identify and address essential elements of effective product development and maintenance processes.

What are the 5 levels of CMMI?

One of the defining features of CMMI is its maturity model, which provides a structured framework for assessing and improving an organization’s process maturity. CMMI defines five maturity levels, each representing a different stage in the organization’s journey toward process improvement and excellence.

Maturity Level 1: Initial

At Level 1, organizations have ad hoc, chaotic processes that are often unpredictable and poorly controlled. There is a lack of defined processes, and success depends on individual effort and heroics. Organizations at Level 1 typically struggle with inconsistency, cost and schedule overruns, and high failure rates.

Maturity Level 2: Managed

At Level 2, organizations begin to establish basic processes, discipline, and control. They define and document standard processes for project management, engineering, and support activities. While processes may still be somewhat reactive, there is a focus on planning, tracking, and ensuring that work is performed according to established procedures.

Maturity Level 3: Defined

At Level 3, organizations have well-defined and standardized processes that are tailored to specific projects and organizational needs. There is a focus on process improvement and optimization, with an emphasis on institutionalizing best practices and lessons learned. Processes are proactive and consistently applied across the organization.

Maturity Level 4: Quantitatively Managed

At Level 4, organizations implement quantitative process management practices to control and manage process performance. They collect and analyze data to understand variation, predict outcomes, and make data-driven decisions. There is a focus on continuous measurement and improvement to achieve predictable and stable process performance.

Maturity Level 5: Optimizing

At Level 5, organizations focus on continuous process improvement and innovation. They actively seek out opportunities to improve processes, products, and services through experimentation, innovation, and organizational learning. There is a culture of excellence and a commitment to driving ongoing improvement and innovation throughout the organization.

Let’s understand How the Architecture of Appium Works

Appium is basically an HTTP server. This server is written in Node.js and it helps to create multiple web Driver session against different platforms. This Appium server receives request from java client which listens for commands from Appium Server.
Let’s have a look at Appium in detail with this video representation.

The way of working of Appium server is almost the same as in selenium RC. The way iOS and android interact with server is quite different. In case of Ios, an Appium proxy commands to a UIAutomation Script. This script would be running in MAC environment.
This application in Ios is called Instruments. In case of android almost everything is same where the server proxy commands to a UIAutomator test case. UIAutomator is a native UI Automation framework which supports junit test cases.
Now let us look at the command line way in which you can install Appium Server on your windows machine.

FAQs

Why is Appium important in iOS and Android App testing? Is it because of its architecture?

Appium plays a pivotal role in iOS and Android app testing, primarily due to its unique architecture, which allows for seamless cross-platform testing.

This tool operates on a client-server model, enabling testers to write tests in their preferred language using standard APIs. Its significance lies in the ability to test native, hybrid, and mobile web apps without needing to alter the app code.

By supporting Android and iOS platforms, Appium facilitates a more efficient testing process, reducing the time and resources spent on writing and maintaining separate tests for each platform.

This approach not only enhances productivity but also ensures consistency in testing across different environments.

How Appium Architecture Works?

Test Script Initialization:

  • The developer writes a test script using their preferred programming language and the corresponding Appium client library.

Appium Server Startup:

  • The developer starts the Appium Server, specifying the desired capabilities such as the platform (Android or iOS), device details, application path, and other relevant configurations.

Connection Establishment:

  • The Appium client library in the test script initiates a connection to the Appium Server by providing the server’s address (IP and port) and the desired capabilities for the test session.

WebDriver Commands:

  • The test script, through the Appium client, sends WebDriver commands to the Appium Server. These commands include actions like tapping on an element, entering text, or navigating between screens.

Translation and Execution:

  • The Appium Server translates the WebDriver commands into corresponding actions supported by the mobile platform. For example, a WebDriver “click” command might translate to a tap on the screen.

Interaction with Mobile Device:

  • The translated commands are then executed on the mobile device, interacting with the application just as a user would. This interaction includes gestures, input, and navigation.

Response Handling:

  • The Appium Server captures the responses from the mobile device and communicates them back to the Appium client. These responses may include success or failure indicators, as well as any relevant data.

Test Script Completion:

  • The test script processes the responses received from the Appium Server, making decisions based on the success or failure of each command. The script may also include assertions to verify the expected behavior of the application.

Session Closure:

  • Once the test script completes its execution, the Appium Server closes the WebDriver session, releasing the resources associated with the test session.

How To Start the Appium server in CMD?

To start the Appium server via the Command Prompt (CMD) on Windows or Terminal on macOS/Linux, you first need to have Appium installed. If you haven’t installed Appium, you can install it using Node.js’s package manager (npm) with the following command:

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

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.

testbytes-mobile-app-testing-banner

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.

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.

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

Crash

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

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

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

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

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

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

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
