I'd like to expand the course a bit and cover more testing topics, so if anyone has suggestions I'm all ears.

Ideally I'd love to hear about situations that were particularly hard to test and (if possible) solutions you used to address the problems.

Eg testing subprocesses is a tricky thing to do, but there are a few ways to write test cases that can be used as a mock subprocess and this has become a relatively useful technique for companies like Hashicorp.

I'm guessing other similar testing ideas exist, but aren't covered in the course and I'd love to research them more and add them.
