A Comprehensive Guide to Regression Testing in Video Games

Ensuring your video game is bug-free and reliable is crucial in today’s fast-paced gaming world. To achieve this, you must conduct thorough game testing throughout the game development process. However, as you build your video game, you will make many revisions and changes to modify and improve its performance, user interface, or other key elements of your game. These functional and non-functional changes may affect the performance of other game features. And that’s where regression testing comes in.

But what is regression testing? Why does it matter? And what are some best practices to consider when performing regression testing? Join us as we comprehensively explore regression testing, ensuring your game maintains reliability and quality, even after making changes.

What is Regression Testing?

The idea behind regression testing is to rerun different tests on your video game (functional and non-functional) after making updates. It helps ensure the new code changes do not introduce bugs. This is because a simple code change can bring new logic that differs from the existing game code, resulting in defects. Even though regression testing may seem repetitive, it helps create a reliable and strong video game.

Game QA teams usually have several regression test cases for crucial features that they re-run every time they make code changes. These test cases are smartly selected based on priority and risk. As a result, it helps maximize team efficiency and save time.

Why is Regression Testing Important in Video Games?

Regression testing is crucial in game QA. Here are some reasons why every developer must consider regression testing in video game development:

1. Detect New Bugs Early

As initially stated, regression testing involves re-testing your video game after making code changes. This re-testing process can uncover defects introduced by the latest modifications. As a result, it becomes easier to find and fix bugs in your video game. Detecting and fixing these bugs early is cost-friendlier than later in video game development.

2. Minimize Risk of Changes

Video game requirements evolve constantly. These changes introduce a risk of introducing errors or inconsistencies in performance. And that’s where regression testing comes in handy. Regression testing allows you to check whether the changes made might have introduced inconsistencies in other aspects of your system. This helps you fix any issues associated with the new changes, reducing the risk of new code updates affecting other areas of your video game.

3. Save Cost and Time

Regression testing demands a significant investment of resources. However, it pays off by preventing defects that may be costlier if they occur after releasing your video game to the public. Also, automated regression testing tools can help optimize your testing efforts.

4. Enhance User Experience (UX)

Regression testing allows you to verify that existing video game capabilities work as intended, even after making updates. The outcome? A seamless user experience between video game releases. With better user experience comes increased player satisfaction and retention.

Factors to Consider to Improve Regression Testing in Video Games

Here are several best practices to consider when conducting regression testing in video games to enhance your outcome:

1. Embrace Automation Where Possible

As initially stated, regression testing is a resource-intensive process. Embracing automation can help minimize the amount of resources and time required to execute repetitive test cases. Also, it helps minimize human inconsistencies and errors, resulting in better regression test outcomes.

You can use different frameworks and tools to create and execute automated tests, including performance, integration, functional, and unit tests. Even better, you can integrate automated tests into your CI/CD pipelines. This allows you to run them regularly and obtain immediate feedback on your code functionality and quality.

2. Prioritize Your Tests

Every video game has many aspects that need to be tested. However, some are more crucial than others, as they are critical to your game performance. Note that testing everything every time you make changes is inefficient and impractical. And that’s where prioritization comes in.

Prioritize what you test during regression testing. Focus on the riskiest and most critical aspects of your game, including gameplay mechanics, security, compatibility, and core features. You can leverage various techniques, like impact analysis, risk-based testing, and test coverage analysis, to prioritize your tests. By prioritizing your test cases, you can optimize the testing resources. Also, it ensures you capture the most critical issues and bugs.

You might well be aware of the challenges in Regression testing for Gaming Applications. Thus, you need an expert’s help to get it sorted out.

3. Collaborate with Your Team

Thorough regression testing is a collective effort rather than a solo activity. Therefore, you must collaborate with your team members to effectively perform regression testing. You can embrace various platforms and tools, such as version control systems and issue trackers, to coordinate and collaborate with team members.

What’s more, embrace agile practices, like sprint planning, daily stand-ups, and retrospectives, to share ideas, progress, feedback, and challenges. This way, you can improve the testing efficiency and quality. Also, it helps foster a culture of continuous learning and quality.

4. Embrace the Test-Driven Development Approach

The test-driven development (TDD) approach involves creating tests before writing the code. This method enables you to design and implement your video game code more effectively and minimize the number of defects and bugs. But how does it help in game testing?

When you create tests beforehand, you can quickly define the expected functionality and behavior of your video game. Also, it helps you define the criteria for failure and success. Therefore, it ensures your game code meets the predefined specifications and requirements, preventing unnecessary complexity and over-engineering.

5. Learn from Mistakes

Regression testing is not all about identifying and fixing bugs – it’s also about reducing and preventing them. To achieve this, you must learn from your mistakes. You can use several tools and methods, like root cause analysis and defect reports, to analyze and learn from your testing results.

Also, you can utilize multiple channels and sources to collect and analyze user feedback. This way, you can improve your regression testing knowledge and skills. The outcome? Better game design and releases, enhancing user experiences.

Final Thoughts

Regression testing is crucial in game quality assurance. It helps you identify defects and bugs associated with code changes. Detecting these issues as soon as the changes are made prevents you from releasing a game with bugs and errors, which may affect players’ gaming experience. However, it is a resource-intensive and repetitive process. Therefore, you must consider various best practices to improve your testing results and ensure consistency. These measures include embracing automation, collaboration, continuous learning, and prioritizing tests. This way, you can deliver a reliable and high-quality video game.
