The tests for "describe" atom and its friends currently run on the main repo of t6300, expect for the test for "bare describe", which is run on "describe-repo". Things can get messy with the other tests when such changes to a repo are done (for example, a new commit or a tag is introduced), especially in t6300 where the tests depend on commits and tags. An example for this can be seen in [1], where writing the tests the current way fails the test "Verify sorts with raw:size" on linux-sha256. This, at first glance, seems totally unrelated. Digging in a bit deeper, it is apparent that this behavior is because of the changes in the repo introduced when writing the "describe" tests, which changes the raw:size of an object. Such a change in raw-size would have been, however, small if we were dealing with SHA1, but since we are dealing with SHA256, the change in raw:size is so significant that it fails the above mentioned test. So, run all the "describe" atom tests on "describe-repo", which doesn't interfere with the main repo on which the tests in t6300 are run.
