Motiviation

Currently it's only supported to debug a specific test. This PR allows to start the debugger on a file.

Special notes for reviewer:

This PR is based on #202

Hey @hown3d 👋 and many thanks for this!

I'll have a thorough look at this during the coming days. Looks nice, from just having skimmed the diff.

Could you describe your use case of debugging a test file (instead of just a single test)?
Does the debugger run through each test?
I'm just curious, that's all 😄

Yes, the debugger does execute all files. Use case would be for breakpoints on functions that are called from multiple tests.

Sorry about this @hown3d I messed up and forgot to add you as co-author to the commit which I squash-merged. Anyhow, your changes are in! 🎉

Thanks again!
