What is the difference between the SIT and UIT phases?
💡 Model Answer
SIT (System Integration Testing) focuses on verifying that individual modules or components work together as a complete system. It tests interfaces, data flow, and integration points between subsystems. UIT (User Interface Testing), on the other hand, concentrates on the graphical or textual interface that users interact with. It checks layout, navigation, input validation, and usability. While SIT ensures the system’s internal logic and integration are correct, UIT ensures the external presentation and user experience meet design specifications.
