I broke out the error retry logic into a named function that could be tested independently of the rest of the event processing framework. This allows the test to know when the retry logic is done. The problem with the original test was there was no reliable way to know when it was done trying record an event. A sentinal event was being used, but there is no ordering guarantee. I could have added synchronization around attempts tracking to fix the data race, but the test case was still fundamentally flawed and would error occasionally.
