We are creating test cases from top to bottom:
- First area/subareas are defined
- Then we have specific change request for that area. Change request has set of target platforms, user story, acceptance criteria. We create section for that change request
- After that we define test cases under the section - simply type titles
- And finally every test case is defined in more detailed steps, expected results, test data, etc.
With this approach in 99% of time all test cases in the section has the same field values like Platform, Owner, Milestone, References, Status, Priority, Type. So it would be more convenient to define all of these fields values at the section level and automatically have them in all new test cases under Section.
