With ExUnit is there a way to only show files that have a failing test? Ideally ExUnit would run all my tests but fail each file as soon as there is a failing test in that file.
My use case is that when I make a large change to the system, I want to focus on test failures one file at a time, but right now there is not an easy way to find files with test failures without running all my tests (in an umbrella project) and then scrolling up to see which tests failed, and checking what files there are in. Since test failures often have very large output it is difficult to find more than one failing file in this way.
I’m not sure what you mean by “failing fies”, as tests are failing and not files, but do you know about the --stale option? It runs only those tests, that are affected by the changes you made snce the last run.
