Which test was the previously run test will vary every run with a different seed, using rspec random testing. With javsscript RSpec and Minitest, this is not enabled by default, and javasccript have to tell them to use Capybara with the JavaScript driver for indvidual tests that need it.

Unfortunately, this makes them much, much slower than when you were running the tests using rspec. Better just fix your test to wait properly on the expected UI, if you at all can.

If you turn off random test capybra, all your feature tests end up running in sequence together, and all your other tests end up running in sequence together, without intermingling.
