I'm trying to run the tests on a patch on Drupal.org. The relevant issue is here. The status is marked as Test request sent but more than a week has passed and the test hasn't been run.
I tried changing the issue status from Needs review to Needs work and then back to Needs review but that didn't re-queue the test. If the test has been run, whether it succeeded or failed, there is usually a Re-test link, but since the test is marked as "test request sent" then the link does not appear.
How can I re-queue such a test?
