Joe Witt commented on NIFI-12768:
---------------------------------
New PR will remove the same pattern of checks in the same test but preceding
the change already made in this JIRA. It presumes ordering that isn't
guaranteed which makes these already timing dependent tests worse.

> The TestListFIle class has not changed substantively in quite some time, but
> it has begun to fail more recently across multiple platforms on GitHub Action
> runners.
> The {{testFilterAge}} method often fails with the same stack trace:
> {noformat}
> Error: org.apache.nifi.processors.standard.TestListFile.testFilterAge --
> Time elapsed: 6.436 s <<< FAILURE!

> The test method use recalculated timestamps to set file modification time, so
> the problem appears to be related to these timing calculations.
