Which testing approach focuses on the interaction of various game segments?

Integration testing is the approach that focuses on the interaction of various game segments. In this testing type, individual modules and components of a game are combined and tested as a group to ensure they work together correctly. This is particularly essential in game development where different systems, such as graphics rendering, physics calculations, and player input, interact closely. By conducting integration testing, developers can identify issues that may arise from the collaboration between these components, which can be overlooked during unit testing, where only individual segments are assessed in isolation. Overall, integration testing helps ensure that the various systems in a game function as intended when they interact with one another.
