Matthias Pohl commented on FLINK-33283:
---------------------------------------
I did a test run where I repeatedly run
{{WebFrontendBootstrapTest.testHandlersMustBeLoaded}} only (see
[2a0627e|https://github.com/XComp/flink/blob/2a0627e9d6cc5f12462cfc7de2c58acb85e666fd/.github/workflows/flink-ci-template.yml#L286-L290].
I wasn't able to reproduce the error (grep over the build's log artifacts):
{code:bash}
$ grep -c "Tests run: 1" *module*/*_Test*txt
ci Test (module connect_1)/12_Test - connect_1.txt:5536
ci Test (module connect_2)/12_Test - connect_2.txt:6136
ci Test (module core)/12_Test - core.txt:4866
ci Test (module misc)/12_Test - misc.txt:5602
ci Test (module python)/12_Test - python.txt:5922
ci Test (module table)/12_Test - table.txt:5522
ci Test (module tests)/12_Test - tests.txt:5806
$ grep -c "Tests run: 1, Failures: 0" *module*/*_Test*txt
ci Test (module connect_1)/12_Test - connect_1.txt:5536
ci Test (module connect_2)/12_Test - connect_2.txt:6136
ci Test (module core)/12_Test - core.txt:4866
ci Test (module misc)/12_Test - misc.txt:5602
ci Test (module python)/12_Test - python.txt:5922
ci Test (module table)/12_Test - table.txt:5522
ci Test (module tests)/12_Test - tests.txt:5806
{code}
The number of test runs matched the number of test runs w/o a failure.
