Test Directory Documentation

[Trott]

The test directory has a number of subdirectories that could use some explanation. It is probably a good idea to add a README to that directory to explain what each subdirectory is and whether or not the tests in that directory get run on the continuous integration server or not. (Look at the test-ci task in the Makefile to find out.)

I'm labeling this good first contribution even though a first-time contributor might not know what all the directories are. Don't worry about it, First Time Contributor! Just take your best guess after perusing the test files in each directory for a little bit and any mistakes will get sorted out in the pull request conversation.

Howdy, i've had a stab at this here, if you have any feedback that would be great! You can preview the rendered markdown here.

This may be a good a time as any to talk about our debugger directory doing nothing

Removing the good first contribution label since we have a viable PR for it now. (Thanks, @mike182uk!)

@thealphanerd Working on it, one test file at a time. #5532

[Trott]

This was fixed (at least an initial doc) by @mike182uk so I'm going to close this issue.
