I'm having trouble with test cases.
I have two questions:
- Is it necessary to make test cases for all use cases / user stories? Or is it enough to just make test cases for the most important functionality (including documents etc.)?
- Imagine I've made a test case for an ordering system. My test of the ordering system fails, so I give a description of how I encountered this error. So the developers fix this error and now I have to test it again. Do I simply use the same test case as previous? If I do, do I just increment the version of the test case document?
