Depending on your goals, budget, and timeline, you can choose from different game testing methods and techniques. Unit testing verifies the functionality and logic of individual components or modules, while integration testing checks how different components interact with each other and external systems. System testing looks at the game system as a whole to test its functionality, performance, reliability, security, and compatibility. User acceptance testing examines the game's usability, accessibility, and satisfaction with real or representative users. Beta testing uses a large and diverse group of users to identify and fix bugs, glitches, and errors. Lastly, playtesting assesses the game's gameplay, mechanics, story, and aesthetics with players. Automating or facilitating your testing processes can be achieved by using tools such as game engines, testing platforms, debuggers, emulators or analytics software.
