+If your PR is failing to pass our CI build due to a test failure, then:
+
+1. Understand if the failure is due to your PR or an unrelated unstable test.
+1. If you suspect it is because of a "flaky" test, and not due to a change in your PR, then please do not simply wait for an active maintainer to come and help you, but instead be a proactive contributor to the project - see next steps.
+1. Search for the name of the failed test on https://issues.apache.org/jira/, e.g. for `AccountingScenarioIntegrationTest` you would find [FINERACT-899](https://issues.apache.org/jira/browse/FINERACT-899).
+1. If you find previous comments "proving" that the same test has arbitrarily failed in at least 3 past PRs, then please do yourself raise a small separate new PR proposing to add an `@Ignore // TODO FINERACT-123` to the respective unstable test (e.g. [#774](https://github.com/apache/fineract/pull/774)) with the commit message mentioning said JIRA, as always.  (Please do NOT just `@Ignore` any existing tests mixed in as part of your larger PR.)
+1. If there is no existing JIRA for the test, then first please evaluate whether the failure couldn't be a (perhaps strange) impact of the change you are proposing after all.  If it's not, then please raise a new JIRA to document the suspected Flaky Test, and link it to [FINERACT-850](https://issues.apache.org/jira/browse/FINERACT-850).  This will allow the next person coming along hitting the same test failure to easily find it, and eventually propose to ignore the unstable test.
+1. Then (only) Close and Reopen your PR, which will cause a new build, to see if it passes.
+1. Of course, we very much appreciate you then jumping onto any such bugs and helping us figure out how to fix all ignored tests!

 and it involves refactoring, try to differentiate "new Feature code" with "Refactored" by placing
 them in different commits. This helps review to review your code faster.
