@gsakakihara I am not actually sure it's fixing anything, I got an error message saying:

Main looper has queued unexecuted runnables. This might be the cause of the test failure. You might need a shadowOf(Looper.getMainLooper()).idle() call.

Wdyt?

Was there a specific test that failed with this? This is the cause of the test failure some times, but not always. Also, I suspect this wouldn't actual fix the tests since I think @after methods only get called after the test has completed (and would have already failed).

This is the test that keeps failing for me testUnsubscribeFromTopic_withPrefix
