Game testing, a subset of game development, is a software testing process for quality control of video games. The primary function of game testing is the discovery and documentation of software defects (aka bugs). Interactive entertainment software testing is a highly technical field requiring computing expertise, analytic competence, critical evaluation skills, and endurance.





A typical bug report progression of testing process is seen below:

  • Identification. Incorrect program behaviour is analyzed and identified as a bug.

  • Reporting. The bug is reported to the developers using a defect tracking system. The circumstances of the bug and steps to reproduce are included in the report. Developers may request additional documentation such as a real-time video of the bug's manifestation.

  • Analysis. The developer responsible for the bug, such as an artist, programmer or game designer checks the malfunction. This is outside the scope of game tester duties, although inconsistencies in the report may require more information or evidence from the tester.

  • Verification. After the developer fixes the issue, the tester verifies that the bug no longer occurs. Not all bugs are addressed by the developer, for example, some bugs may be claimed as features (expressed as "NAB" or "not a bug"), and may also be "waived" (given permission to be ignored) by producers, game designers, or even lead testers, according to company policy.
