@zedmonds96 can we follow the pattern for other tests on this class, to check for the logger execution as well? If you look at ImportQueueWorkerTest::testErrorPath() I think you'll see a pattern you can use in ::testProcessItemAlreadyImported().

@dafeder is this cypress test failure related to my changes?

[dafeder]

I'm sure it's a random failure we keep getting on that test. Can you rerun it?

I think I added this check correctly, but not 100% sure.
