Question: when coming up with tests (whatever level they might be) before you submit your code, what’s your thought process about what tests to include? What edge cases to handle? What to not test? Is there much disagreement about what to test?
I would say there wasn't much disagreement there. I typically started out by writing tests for the simple cases, then I would identify edge cases through actual usage of the feature locally, and write tests for those as well. Also, whenever bugs were found, I would write "regression test cases" for those when fixing.
