Thorough game testing improves quality, shapes the player experience, and reduces development risks before launch. This makes for more polished, enjoyable games as well as saving development time and costs down the line. The testing insight translates into tangible improvements that players appreciate.

Introduction to Game Testing Methodology

Game testing methodology refers to the practices and procedures followed to evaluate game software for defects across parameters like graphics, gameplay logic, UI, controls, etc. It identifies issues so developers can fix them before release. 

Effective game testing methodology is crucial because, unlike other software, games focus heavily on user experience. Shortcomings like glitches, crashes, lag, bugs etc. severely hurt enjoyment and retention. Thorough testing across facets is vital for shipping playable, immersive games.

The fundamental approaches used are:

Manual Game Testing Methodology

This involves human testers methodically playing through game builds to evaluate aspects like visuals, controls, in-game elements etc. It assesses overall gameplay experiences as end-users would.

How Manual Testing Is Conducted

Dedicated QA teams are tasked with manually testing builds. Testers develop test plans covering areas like:

  • Graphics/visuals (textures, lighting, animations etc.)
  • Controls & UI (keybindings, controller support, menu navigation etc.)
  • Core mechanics & gameplay (physics, character abilities, AI etc.)
  • Levels & environments (level design, bugs, completion etc.)
  • Audio (sound effects, music, voice acting etc.)

They playtest builds multiple times while noting issues in bug-tracking systems. Exploratory testing without test cases is commonly used for quickly checking new features, builds etc. More formal scripted testing happens later covering predefined test cases.

Testers also verify fixes for reported bugs in new builds to ensure problems are properly addressed. Regression testing on unchanged parts also takes place to catch new issues that manifest.

Advantages of Manual Testing

  • Assesses subtle qualitative aspects like fun, and user experience effectively
  • Human testers lend real-world gaming perspectives and feedback
  • Natural manual playthroughs properly judge the intricacies of gameplay

Disadvantages of Manual Testing

  • Very time-consuming and labor intensive
  • Hard to manually test all possible scenarios
  • Prone to human error and oversight
  • Skill levels of testers impact thoroughness

Automated Game Testing

This uses specialized software tools that can simulately “play” the game by programmatically sending inputs and testing for expected outcomes.

How Automated Testing Works 

Dedicated programmers create automated test suites using unit test frameworks like Unity Test Runner, writing test scripts that:

  • Launch game builds
  • Input simulated player actions via API commands (keyboard, controller buttons etc.)
  • Obtain game state data like health, scores etc. via inspection APIs
  • Validate expected vs actual outcomes using assertions
  • Log test results/failures for reporting

These tests are run repeatedly without human intervention, like overnight test cycles. Tests are augmented to cover new features and builds.

Advantages of Automated Testing

  • Extremely fast at testing systematically
  • Achieve very high test coverage
  • Can run 24/7 without human oversight
  • Eliminates human error risks
  • Consistent objective testing

Disadvantages of Automated Testing

  • Considerable programming skills/effort needed
  • Not effective for testing complex gameplay elements
  • Lacks human visual/UX judgments

As visible above, both manual and automated testing have significant complementary strengths and shortcomings. Using them judiciously as per context is key to robust game testing.

Game Testing Techniques and Tools

Here are some foremost game-testing methodology techniques and tools:

Functional Testing

Evaluate core components like mechanics, UI, controls, etc. for defects. Commonly used techniques are exploratory testing, beta testing, regression testing etc. Tools include Unity Test Tools, Unreal Automation Toolset etc.

Exploratory Testing: Testers play game builds without predetermined test cases to explore and find issues leveraging their gaming experience. Useful for checking new features.

Beta Testing: Releases early game builds to select external volunteer players for feedback to fix issues and refine gameplay. Provides real-world testing data.

Regression Testing: Retesting previously checked builds after changes to ensure existing functionalities still work as expected. Vital before major releases.

Ad Hoc Testing

Informal testing without detailed scripts to experiment freely and uncover unexpected issues. Useful for rapidly checking newly added components. Unreal Automation Toolset has built-in support for ad hoc testing.

Performance Testing

Evaluate game performance parameters like frame rates, response time, lag, load capacity etc. under different simulated hardware environments and player loads. Useful tools are FPS Monitor, AppAnalyzer, Unity Performance Testing extension etc.

Compatibility Testing

Testing games on target platforms like consoles, PCs, mobile devices etc. having various hardware configurations like GPUs, CPUs plus software environments like Operating Systems to ensure compatibility. Helpful tools are BrowserStack, Squad, TestObject etc.

Localization Testing

Validating UI strings, audio translations, graphics rendering etc. work correctly localized into target languages. Useful techniques involve in-house reviews, and beta testing native speakers. Tools like LocLaunch, Smartling, POEditor etc. help manage testing.

Globalization Testing

Testing localized game builds for issues stemming from regional variances in date/time formats, units (metric vs imperial), cultural sensitivities (symbols, colours), currency formats etc. Manual testing along with beta testing native users commonly performed.

Accessibility Testing

Assessing game usability and playability for people with disabilities like hearing, vision, and motor impairments. Manual testing techniques aided by tools like FANGS, and GTAG Accessibility Plugin. Important for inclusive game design.

Tree Testing

The technique where game testers methodically traverse all decision paths in narrative/dialogue-heavy games for consistency issues. Useful tools are Twine, ChatMapper etc. Helps address non-linear branching complexities.

Security Testing

Checking game code and infrastructure for security issues like exploits, data leaks, and attacks to address vulnerabilities before launch. Useful techniques are fuzzing, penetration testing, risk assessment etc. Tools include AuthMatrix, Load Impact, OWASP ZAP etc.

Clean Room Testing

Having separate test teams create test cases based solely on game design docs before playing builds. Then formal testing built against those prerelease cases reveals defects more accurately. labor-intensive manual technique but yields actionable bug reports.

Game Testing Methodology Process

Game testing is crucial as per the current market scenario. Growing exponentially due to the increased use of mobile and tablet applications, specifying a standard game-testing methodology is difficult.
