Once you have retriggered/backfilled a job, now you wait for it to finish. opt tests usually finish in <30 minutes once they start running- debug can be up to 1 hour. | |||
When your initial tests finish, you might see a view like this: | |||

Here you can see the 2-4 oranges per push. Look at each of the failures and make sure the same test is failing. In the above case that is true and we need to go further back in history. | |||
After repeating the process a few times, the root cause will become visible: | |||

You can see that we switched from bc1 -> bc2 as the failing test, so now the filter is on bc instead of bc1. you can see a clear pattern of failures for every push and then almost no failures before the offending patch landed. | |||
