The Ruby `minitest` API used to have a way to disable non-deterministic test ordering, but it was intentionally named in a condescending way: https://www.rubydoc.info/gems/minitest/Minitest%2FTest.i_suck_and_my_tests_are_order_dependent https://www.rubydoc.info/gems/minitest/Minitest%2FTest.i_suc...! I sometimes run into issues not so much due to order dependencies specifically, but due to tests running in parallel sometimes causing failures due to races. It's almost always been way more work to convert a fully serial test suite into a parallel one than it is to just write it that way from the start, so I think there's some merit in having test frameworks default to non-deterministic ordering (or parallel execution if that's feasible) with the ability to disable that and run things serially. I'm not dogmatic enough to think that fully parallel/random order tests are the right choice for every possible use case, but I think there's value in having people first run into the ordering/race issues they're introducing before deciding to run things fully serially so that they hopefully will consider the potential future work needed if they ever decide to reverse that decision.
