What is the purpose of system integration testing (SIT)?
a) To test the interaction between different components or subsystems of the software
b) To test the user interface design
c) To test the performance of individual components
d) To test the security features of the software
Answer:
a) To test the interaction between different components or subsystems of the software
Explanation:
System integration testing (SIT) is a phase in software testing where the interaction between different components or subsystems of the software is tested. SIT ensures that all modules work together as expected when integrated.
This testing is conducted after individual components have passed unit testing. SIT focuses on validating data flow, communication, and dependencies between integrated modules.
System integration testing is essential for identifying issues that may not appear in isolated components but arise when the system is assembled as a whole.
