Software testing is more than just error detection

Testing software is operating the software under controlled conditions, to (1) verify that it behaves “as specified” (2) to detect errors, and (3) to validate that what has been specified is what the user actually wanted.

1.　　Verification is the checking or testing of items, including software, for conformance and consistency by evaluating the results against pre-specified requirements. [Verification: Are we building the system right?]

2.　　Error Detection: Testing should intentionally attempt to make things go wrong to determine if things happen when they shouldn’t or things don’t happen when they should.

3.　　Validation looks at the system correctness – i.e. is the process of checking that what has been specified is what the user actually wanted. [Validation: Are we building the right system?]
