@lonnblad Thanks for the addition of the cucumber test, but I'm really not into that particular file being +4k lines. Would you be able to put that (and possibly the other outputs) into their own files as fixtures the tests can load, please?

Do you think you'd be able to run all three tests in the same file, too?

[lonnblad]

sure, do you want it in something like fixtures/cucumber_output.json and fixtures/junit_output.xml?

Heyo, much nicer! 🎉
