Just a little tool I use to help track test changes when I'm making large changes to Bikeshed.

To use: make sure that main-unaltered contains the contents of bikeshed/tests on the main branch (what you're diffing against), then make sure bikeshed is on your test branch, with updated tests. Then run ./test; the file diff.txt will contain the diff results.

The tool does some normalization to the test files to remove noisy differences that are unlikely to matter. You can adjust what's normalized in the setup.py file.
