> Key: BEAM-12672
> URL: https://issues.apache.org/jira/browse/BEAM-12672
> Project: Beam
> Issue Type: Test
> Components: testing
> Reporter: Alex Amato
> Priority: P2
>
> We should configure the precommit test suites to re-run failed tests a few
> (K) times.
> (A bonus feature would be to tag certain tests as known flakey, and run
> multiple attempts in parallel when the test is first ran)
> The benefits of this are to:
> * Not have flakey tests slow down PR reviews and merges.
> * And avoiding the need to repeatedly manually rerun the precommit test with
> a PR comment.
> * Getting a clear signal that failed tests are due to the code in the PR
> * Save computing resources (Rather than needing to run the entire test suite
> every time it fails, only the failed tests will rerun).
> (Its not realistic to have 0 flakeyness, so this is desirable to improve
> productivity, as it can take several attempts to have all the tests pass in a
> single run).
> Note: This does not mean that we should ignore flakey tests, which are
> sometimes indicative of bugs. We should continue to investigate those with a
> continuous test suite.
