A Software Testing Traceability Matrix (STM) is a document that links and maps test cases to their respective requirements, ensuring that each requirement has been adequately tested.
It serves as a verification tool to confirm that all software requirements, as defined in the requirements specification document, are covered by test scenarios and cases.
The matrix facilitates identifying missing tests, understanding the impact of changes, and ensuring comprehensive test coverage.
By maintaining traceability from requirements through to test cases and defects, STMs provide clear visibility into the test coverage, project progress, and quality assurance process, aiding in effective project management and delivery.
Benefits of Using Traceability Matrix
The Software Testing Traceability Matrix (STM) is critical for several technical and project management reasons:
Ensures Coverage: STM guarantees that all requirements are tested, minimizing the risk of untested functionality being released. It systematically matches requirements with test cases, ensuring comprehensive coverage.
Impact Analysis: It facilitates efficient impact analysis by identifying which test cases are affected by changes in requirements, thereby streamlining regression testing and reducing the risk of introducing defects.
Defect Traceability: STM links defects to their corresponding requirements and test cases, making it easier to pinpoint the source of defects, understand their impact, and prioritize fixes.
Project Management: It gives stakeholders a transparent overview of testing progress and requirement coverage, aiding in project tracking, planning, and decision-making.
Compliance and Audit: For projects under regulatory scrutiny, STM demonstrates due diligence and adherence to quality standards by providing auditable evidence of requirement coverage and testing.
Efficiency in Test Maintenance: By clearly linking requirements to test cases, STMs simplify the maintenance of test suites, especially in agile and rapidly changing environments.
Communication: It enhances communication among team members by providing a clear and common understanding of what needs to be tested, the testing scope, and the rationale behind test case selection.
Types of Software Testing Traceability Matrix
Mentioned below are the key types of software testing traceability matrixes:
Forward Traceability
Forward traceability focuses on mapping requirements to test cases. It ensures that every requirement has corresponding test cases designed to validate it. This type of traceability ensures completeness in testing efforts by confirming that all specified functionalities are covered by test cases.
Backward Traceability
Backward traceability involves tracing test cases back to the originating requirements. It ensures that every test case has a clear association with one or more requirements. This type of traceability helps in validating the necessity of each test case and identifying any redundant or obsolete ones.
Bidirectional Traceability
Bidirectional traceability combines both forward and backward traceability, establishing a two-way mapping between requirements and test cases.
It ensures not only that each requirement has corresponding test cases but also that each test case is linked back to the originating requirements. This comprehensive approach provides a thorough understanding of the testing coverage and its alignment with the project requirements.
Vertical Traceability
Vertical traceability extends beyond requirements and test cases to encompass other artifacts throughout the software development lifecycle, such as design documents, code modules, and user manuals.
It enables stakeholders to trace the evolution of various elements across different phases of development, ensuring consistency and coherence in the final product.
Horizontal Traceability
Horizontal traceability focuses on establishing relationships between artifacts within the same development phase. For example, it may involve linking test cases to each other based on shared test objectives or dependencies.
This type of traceability enhances collaboration and coordination among testing teams, ensuring that efforts are synchronized and aligned toward common goals.

How to Create TM (Traceability Matrix)?
Creating a Traceability Matrix (TM) involves systematically linking project requirements with their corresponding test cases, test results, and any related issues or defects. This ensures that every requirement is adequately tested and accounted for. Here’s a step-by-step guide to creating an effective Traceability Matrix:
Step 1: Identify Your Requirements
Gather Requirements: Start by collecting all project requirements from the requirements documentation. This includes functional, non-functional, and system requirements.
Assign Unique Identifiers: Give each requirement a unique identifier (ID) for easy reference and tracking.
Step 2: Outline Your Test Cases
List Test Cases: Identify all test cases that have been designed to verify the requirements. This includes both automated and manual test cases.
Assign Identifiers to Test Cases: Similar to requirements, assign a unique ID to each test case for easy referencing.
Step 3: Create the Matrix Structure
Choose a Tool: Decide on a tool or software to create the matrix. This can range from simple tools like Microsoft Excel or Google Sheets to more sophisticated test management tools that offer traceability matrix features.
Set Up the Matrix: Create a table with requirements listed on one axis (usually the vertical axis) and the test cases listed on the other (usually the horizontal axis).
Step 4: Map Requirements to Test Cases
Link Test Cases to Requirements: For each requirement, indicate which test cases are intended to verify it. This can be done by placing a mark, such as a checkmark or a test case ID, in the cell where the requirement row and test case column intersect.
Ensure Full Coverage: Make sure every requirement has at least one test case linked to it. If any requirement is not covered, you may need to create additional test cases.
Step 5: Include Additional Information (Optional)
Add Test Results: You can extend the traceability matrix to include the results of each test case (Pass/Fail/Blocked).
Link to Defects: If applicable, include columns to link failed test cases to reported defects or issues, providing a direct trace from requirements to defects.
Step 6: Maintain the TM
Update Regularly: Keep the TM updated with any changes in requirements, additions or modifications of test cases, and updates in test results or defect status.
Review for Completeness: Periodically review the TM to ensure it accurately reflects the current state of the project and all requirements are adequately tested.
Step 7: Utilize the TM for Reporting and Analysis
Analyze Test Coverage: Use the TM to identify any gaps in test coverage and address them.
Support Impact Analysis: Leverage the TM to assess the impact of requirement changes on existing test cases and defects.
Creating and maintaining a Traceability Matrix is a dynamic process that requires ongoing attention throughout the project lifecycle. It’s a powerful tool for ensuring that all project requirements are met and that the final product is of high quality.
A Software Testing Traceability Matrix is a fundamental tool for managing and tracking the testing process in software development projects.

Test Execution: Testers manually execute the test cases and document the outcomes during this phase. They compare the actual and expected results to identify any discrepancies or defects.
Peer Testing (Added Step):
Integration into Workflow: After individual test case execution, peer testing is introduced as an additional step. This involves having another tester, who did not originally write or execute the test case, review and re-run the tests.
Benefits: Peer testing brings a fresh perspective to the testing process, often uncovering issues the original tester might have overlooked. It enhances test coverage and accuracy by leveraging the collective expertise of the testing team.
Execution: Testers can perform peer testing in pairs or small groups, discussing findings and insights collaboratively. This step encourages knowledge sharing and can lead to more innovative testing approaches.
Test Closure: The testing process concludes with a closure report summarizing the testing activities, coverage, defect findings, and an overall assessment of the application’s quality. This report helps stakeholders make informed decisions about the software release.

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:
npm install -g appium
Once Appium is installed, you can start the server by opening CMD or Terminal and running the following command:

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.
Marketing
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.

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:
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.
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.
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.
Report the Outcomes – Complete insights about the bugs are reported.
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.
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.
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.
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.
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.
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.
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.
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..
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:

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:
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.
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.
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
Alpha Testing
The initial testing phase is where the game is evaluated for major bugs.
Involves internal testing by the development team.
Beta Testing
A select group of outside users test the game during pre-release testing.
Aims to identify potential issues and gather user feedback.
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.

#3) Can we use JMeter for UI load testing?
It is not inherently designed for UI (User Interface) load testing in the way tools specifically built for browser-based UI testing are, like Selenium or LoadRunner. However, it’s essential to understand the distinction in the context of UI load testing:
Protocol-Level Testing vs. UI-Level Testing:
JMeter excels at testing the server-side functionality of web applications by simulating network traffic similar to that generated by browsers and other client applications. It’s great for testing APIs, web services, and websites at the HTTP/HTTPS level.
UI load testing, on the other hand, involves simulating user interactions directly with the graphical interface of an application. This requires rendering the UI, which JMeter does not do.
JMeter’s Scope and Capabilities:
JMeter can test how the back-end of a web application handles load, which indirectly impacts the UI performance. For instance, it can test how quickly the server processes requests and returns responses, which is a part of the overall UI responsiveness.
For direct UI performance testing, which includes rendering times, user interactions, and client-side logic performance, a tool that operates at the browser level is necessary
Integrating JMeter with UI Testing Tools:
Although JMeter isn’t a UI testing tool, it can be used in conjunction with UI testing tools like Selenium for comprehensive testing strategies. For example, JMeter can handle the backend load testing, while Selenium automates the user interface interactions.
This combination allows for a more holistic approach to performance testing, covering both the server’s ability to handle traffic and the client-side experience.
Headless Browser Testing:
Some modern testing approaches use headless browsers in conjunction with JMeter. A headless browser is a web browser without a graphical user interface that can be controlled programmatically. JMeter can trigger headless browsers to perform specific UI actions as part of a test plan.
Limitations:
It’s important to note that using JMeter for UI testing is more of a workaround and doesn’t provide the full spectrum of insights that a dedicated UI testing tool would offer.
In summary, while JMeter is a powerful tool for load testing at the server level, its use for UI load testing is limited and generally requires integration with other tools that are specifically designed for UI interaction and rendering.
#4) What cannot be tested using JMeter?
Apache JMeter, primarily designed for performance testing of web applications and services, has certain limitations and cannot be used for specific types of testing.
User Interface (UI) Rendering: JMeter cannot test the rendering of web pages or any graphical elements of the user interface. It doesn’t interact with web pages like a real user and cannot capture UI-related issues or measure client-side rendering times.
Browser-Specific Issues: Since JMeter does not execute JavaScript or render HTML like a web browser, it cannot test browser compatibility or detect issues specific to web browsers.
Mobile Application Testing: JMeter is unsuitable for testing the native functionalities of mobile apps. While it can test server-side services used by a mobile app, it cannot interact with or test the app’s UI on a mobile device.
Detailed Network Analysis: JMeter does not provide detailed insights into lower-level network protocols beyond HTTP/HTTPS, making it unsuitable for testing non-web-based network services or performing deep network analysis.
Security Vulnerability Testing: While JMeter can perform some basic security load tests, it is not equipped for comprehensive security testing, such as penetration testing or vulnerability scanning of applications.
#5) How to run JMeter load test in non-GUI mode?
Running JMeter load tests in non-GUI mode is preferred for performance testing, especially when handling large loads, as it consumes fewer resources. Here’s how you can execute JMeter tests in non-GUI (command line) mode:
Prepare Your Test Script:
First, ensure that your JMeter test plan (.jmx file) is ready. This should be done in the JMeter GUI mode.
Open Command Line Interface:
On Windows, open Command Prompt.
On macOS or Linux, open Terminal.
Navigate to JMeter bin Directory:
Use the cd command to navigate to the bin directory of your JMeter installation.

Your software is in great risk of if it’s not been tested properly. Software industry is aware of this risk and they are giving more prominence to software testers than they used to be, in short, the career is booming at this point.
Testers and developers are integral part of a SDLC. But which career has got more scope?
Before jumping in to it let’s have a look at the major myths surrounding software testing career.
Anybody can test. Development is superior to testing.
Compensations will be less as related to Developers in the business.
There won’t be any career growth in Software Testing.
Just the individuals who can’t code take Software Testing as a profession.
Here are 18 reasons why these assumptions are incorrect:
1. Importance:
Normally there would be two teams working on a venture as both testing and development can’t be separated from each other.
Each written code must be reviewed for quality and with no team existence; it’d be difficult to develop the final product.
The fact here is that both software testing and software development teams are similarly critical.
It’s a myth that software tester is somewhat of a ‘lower’ rank employee than a software developer.
2. Responsibility:
At the point when any undertaking starts – software testing and developing team both get included to work in sync from the day one.
While the genuine responsibility of software developers starts substantially later, software testers often start at the time of checking the specification archives and proceeds for the duration of the existence of the project.
It’d be right to state that software testers regularly have a superior learning of the comprehensive working of the software frameworks they are taking a shot at.
3. Creativity:
Software testing is steadily showing signs of change, each day there are distinctive ventures and appropriately unique approaches to test them. For instance, all developed mobile apps are required to run on all mobile versions.
So, amid mobile app testing, it’s important to utilize multiple devices with different versions and their operating system platforms.
Another model is cross-browser testing that identifies bugs of a web app. Thus, testers need to get a little imaginative when testing.
The procedure won’t be illuminated for you; indeed, it takes a short spy work. By serving as the end-user, a tester needs to get innovative while considering scenarios that there might be irregularities.
4. A Specialized Talent:
Being a software tester is more often considered a choice since it’s an extremely energizing activity.
The people who haven’t generally worked on testing may believe its exhausting and may spread the incorrect word that you needn’t bother with any specialized skill to be great at it. This isn’t at all true.
Additionally, keeping in mind the goal to detect a few errors, and endeavor to recreate them, just tapping on buttons in a browser won’t be sufficient: you’ve to comprehend the framework under test, find and examine the correct server, have the capacity to utilize tools to slow down the system, and significantly more.
You can be a security tester, an API tester, a penetrating tester. A software tester isn’t an ousted software developer who just taps on some buttons and cross his fingers for a bug to mysteriously show up.
5. Salary Range:
Numerous individuals accept there is a critical distinction in pay between a software developer and software tester, with the former being paid considerably more. Is it right?
The early introduction might be misleading. The compensation relies upon numerous elements, comprising of the scope of work he/she is managing daily, the software testing organization an individual is working for, experience, professional aptitudes, and so forth.
Even, there isn’t much distinction between the salary range of a person from a development team and an accomplished tester. A few organizations, such as Microsoft and Google, give even a higher compensation to the software testers instead of software developers.
To some level, this appears as a result of a higher workforce demand for software testers according tothe latest employment market. Experts, who manage development testing, mobile testing, and website testing, frequently end up being more prevalent at the employment market than software developers.
6. Testers Too Code:
Obviously, in case that you expect to do the automated testing, you’ll be undeniably require coding skillsto be a great tester. It’s an era of automation. The job of an Automation Tester is to write code to automate the scripts. Testers also need to have coding skills.
So, it’s an aged myth in the industry that a person who cannot code can be a “Software Tester”.
7. Evolving Technologies:
Numerous new technologies are splashing up in the product testing world, especially Machine Learning and AI. Despite the fact that the development of both is still somewhat far away, they certainly have a practical usage from a testing viewpoint, and they’re arriving sooner than we might suspect.
They are now affecting the software testing field by making it more entangled, and that effect will just keep on developing. We’re starting to see AI and Machine Learning technologies engaged with more programs, and the potential for those advances to expand testing skills is stunning.
8. Challenging Job:
Testing is not simple, there are regularly puzzles and issues to solve. The software testing profession will possibly bring something different daily.
If you like a profession where you don’t need to think a lot then don’t seek a career in software testing industry. However, in case that you prefer a profession which keeps you on your toes, anybody will direct you towards software testing job as a really good choice.
9. Great Future:
In a world commanded by the technologies like AI, IoT, and Machine Learning, testing will continue to grow at its core.
Notwithstanding these progressions, it’s not unusual that the majority of the professionals emphasizes the requirement for software testers to be available to the revolution and become serious about adopting new techniques too.
As a result, traditional ways to deal with testing are evolving too. At last, such evolution’s are opening more doors for software testers in the testing world, as testing is continually progressing.
Ultimately, every expert believes to be positive about the future of emerging software testing domain. This is because the opportunities for testers are simply growing.
And these possibilities will get more interesting as well because the software testing is becoming a more challenging, engaging and in-demand field so, the future holds a lot.
10. Quality Assurance Demands:
Considering the importance of producing high-quality software, it can be stated that the role of
testers to guarantee quality assurance cannot be neglected. This demand will increase as firms
continue to plan the delivery of defect-free and consistent software.
11. Rising Complexity in Software Systems:
With more complex software systems, the requirement for comprehensive testing in order to
detect and eliminate possible problems increases. Testers play a crucial role in navigating the
functionality of modern software across multiple platforms and situations.
12. User-Centric Approach:
User experience is becoming more and more important which makes user-centric testing
critical. Testers are the key players in detecting usability issues; they ensure that apart from
correctness, software must also deliver user comfort and satisfaction.
13. Shift Left Testing Practices:
There is also the shift-left strategy, where testing is incorporated earlier in development. The
shift to early testing highlights the role that testers play in detecting and resolving problems at
an initial stage, thus lowering the overall project costs.
14. Regulatory Compliance:
Following industry regulations and standards is essential, especially in financial industries,
medical fields or cybersecurity. Testers play a major role in confirming that indeed the software
complies with these standards; this is to ensure compliance on any legal or ethical issues
involved.
15. CI/CD:
Implementation of CI/CD methodology demands continuous testing during the whole life cycle.
The role of testers is crucial for providing smooth integration and deployment processes,
allowing to release software more quickly and predictably.
16. Security Testing:
The growth of cyber-attacks has made security testing part and parcel to the software
development process. Testers who are experts in security help to detect the weaknesses and
provide strong protection against breaches.
17. Globalization and Localization Testing:
With the international implementation of software, it becomes vital to perform testing across
various languages, regions and cultures. Specializing in globalization and localization, testers
help ensure that software products are customized for different markets worldwide creating
more career prospects.
18. Adoption of DevOps Practices:
The proper incorporation of the DevOps practices focuses on promoting coordination between
development and operations. Testers, given their understanding of software quality assurance,
are also key to the seamless integration process associated with DevOps methodologies.
Final thoughts…
