Overall: confirm that everything passes. However, two comments...

Commentary has been left on the originating offensive line in test_latest.py:46. This line still appears to need modification.

WRT the direct_url.json issue: though the tests run when the cwd != <repo_path>, there is a significatnly higher number of SKIPPED tests. When pytest is run in the <repo_path> there are 9 SKIPPED tests. When run from another cwd != <repo_path>, there is 160 SKIPPED tests. Just pointing this out in case this was not intentional.

[WilliamJamieson]

This is expected. If I can't resolve the question of if the install is editable it gives up and assumes that it is not editable. So those tests get skipped.
