What is Test Case? - Software QA Job Interview Question and answer

[wclient]

Thank you for this comprehensive and definitive discussion about test cases. Showing a spectrum perspectives of TC and showing the willingness to adapt to the environment of interviewing companies. A good tactic.

I think a TC = Precondition + Postcondition + Invariants, and it should be blackboxed and repeatable. A test case is to examine the behaviour of modules against their specifications.

In unit test, a specification need not be documented, but perceived in programmers' mind.

@straightfaceliar its a set of test inputs, with expected conditions comparable to the expected outputs.

I like the fact the he provided the different definitions of Test Case. especially for an interview question, you need more information that just a definition. Thank you

very good video - your main point is left until the very end but it is very good advice (and applies to all interviews not just those for a software test job).
