Would that be done based on which (different) tests killed a particular mutant?
Often an integration test would catch the multiple mutations also being caught by (different) unit tests.
I assume that you mean that if a certain (broader) test kills the same mutants as X unit tests, those X tests are not really necessary?
I've looked into https://github.com/boxed/mutmut and https://github.com/sixty-north/cosmic-ray for Python project, and there it is only important that a mutant gets killed, but not how often and by which tests (therefore you can use `pytest -x` to continue with the next mutation after the first test failed due to it).
