Re: [wildfly-dev] The CI Inquisition!

Hello Everyone! Over the last few years we have attempted to get a grip on the intermittent test failures we see in CI almost every run, and have attempted various policies which were poorly enforced. This was mainly due to an understanding of tight deadline, but also a concern that strict enforcement would damage our test coverage. I would find myself holding out in hope that over time we would see these issues decrease. Unfortunately that hope was misplaced, and the simple truth is that coverage is already harmed, because no one pays attention to the intermittent fails, since they are treated as noise and not a true defect. I think we have no other option but to @Ignore any and every intermittent test, no matter the number or area they appear in. So unless someone can propose another workable strategy, intermittent tests should be disabled immediately by anyone that is impacted by them (reviewers, contributors, whoever). To do this, a simple short independent PR should be sent in, and a note should be left in a comment to the component lead of the area tested (using github’s super cool @user syntax). The component lead can then act on the message and choose whether to open and assign a JIRA to have it fixed, to ignore it, to delete it, to rewrite, etc. The intention is that the process of disabling an intermittent test should be as minimal effort as possible. In order for a known intermittent test to be reenabled, it needs to be shown that it is no longer intermittent by completing many full testsuite runs successfully. Anyone that needs it can request a custom CI job run for this purpose. Finally, if you are a saint and decide to fix an intermittent failing test, but have trouble reproducing it, feel free to raise the topic in the WildFly HipChat and we can come up with a solution like custom debug test jobs that can get you the info you need. Thoughts?
