Tip

To only re-run the failed test suites you can provide a TARGET_SUITES parameter with your trigger that points to the directory path of the test suites to run, e.g. /run cluster-test-suites TARGET_SUITES=./providers/capa/standard to re-run the CAPA standard test suite. This supports multiple test suites with each path separated by a comma.
