parts of the
build you should run:
- A full build `make` (build target depends on the repository)
- A full unit test run `make test`
+- For diagnosing flaky tests, which are challenging due to their infrequent
failures, use a looping command to repeatedly run the test. For instance, to
diagnose `TestNoFillWithoutEventPluginRegistered` in
`yunikorn-core/pkg/events/event_publisher_test.go`, you can use the following
command:
+
+ ```sh
+ I=0; while go test -run TestNoFillWithoutEventPluginRegistered ./pkg/...
-count=1; do (( I=$I+1 )); echo "Completed loop: $I"; sleep 1; done
+ ```
Any test failures should be fixed before proceeding.
