Functional testing
What is functional testing? As the name suggests, functional testing is a type of testing where we verify whether a game or part of the game functions as designed. Besides game features, usability and stability testing also fall under the functional testing umbrella. Functional testing literally means that we are testing whether the game and its components are working as they should. This part of testing makes up the bulk of a tester’s job, and it’s considered the main part of testing.
Functional testing is not a specialized discipline, and as such, it’s expected that every tester can execute functional tests, even those at a junior level. While everyone in QA is expected to be able to do functional testing, it often happens that testers, with time, specialize or just become much better at testing specific features of games – for example, testers can specialize in testing achievements, multiplayer games, late gameplay, and so on.
