test: update testing suite to write to a more visible path

[tylerslaton]

Summary

With this fix the testing suite now writes to ./test_runs which is a local directory that git ignores. This should make these runs more visible to easily delete.

Looks good. Can we go ahead and add cleanup for the directory while we're making this change?

Any idea on what happens if the test case assertion fails? Does it drop down to the remove_dir_all function, or does the function flow immediately stop there?

LGTM

Yes, that's a good call-out. We need the equivalent of a defer() or AfterEach() to handle that case

I would think that it would fail to clean-up the directory so thats a good callout. Let me try and find some sort of defer in rust.

There's some workaround using the Drop trait, but it seems complex.
