It would be good to run tier2 on your local setup too - that way any future contributions in this area can be tested locally to verify that changes don't break unexpected existing tests.

Hello @ehs208, I'm investigating a intermittent test failure of the newly added test in our CI. I think the test will need a few adjustments. I haven't had a chance to go over the failure in its entirety. I will add some details here when I am done looking at that failure.
