As you can see, although no errors are reports, diff reports an error about a missing file. By the way, the fact that the test succeeds while an error occurs is already suspicious in itself...
Good point. The configuration of the forwarding plugin was not up to date and it caused the problem. I've fixed it and added a check so the test would fail in such a case in the future.
