Types of Game Testing -Functionality Testing

Functionality Testing
This is the type of testing that is most commonly associated with the phrase "game testing", as it usually entails playing the game in some form. Functionality testing does not require much in the way of technical knowledge, though understanding basic concepts about programming can give testers insight about the possible cause of a problem, which both reduces the amount of work they have to do, and generally makes their reports easier to understand by the developer. Functionality testers look for general problems within the game itself or its user interface. Major issues include stability (does the game crash?), correctness of game mechanics (does the sword deal damage?), and integrity of game assets (are textures corrupted?).
