Your supervisor said that “Integration testing is a waste of time. If each program is tested adequately, integration testing isn’t needed. Instead, we should move on to system testing as soon as possible. If modules don’t interact properly, we’ll handle it then.” Do you agree or disagree with this comment? Explain your answer.

What will be an ideal response?

Students should understand the importance of integration testing in the implementation phase. Because integration testing involves testing with two or more programs, output from one program can be used as input to the second program; through testing in this manner, the systems analysts can be certain that the system is stable. If integration testing is skipped, then the systems testing phase likely will become lengthier, and management approval will not come easily. Some errors will go unnoticed regardless of how well you test, but all forms of testing are important in reaching the end result.
