tl;dr https://builds.apache.org/job/ZooKeeper-Find-Flaky-Tests/lastSuccessfulBuild/artifact/report.html
We all know quality is important to this project. One of major advantage of ZooKeeper comparing to other similar solutions is its quality: solid, stable, and well tested. Unit tests are playing an important role for ZK's quality so we need take these tests seriously. In particular for failed tests, it's easy to blame they are failed because of flaky but usually there are bugs (sometimes very subtle ones) behind the failures. Inspired by some good work done on HBase project, I've borrowed and tweaked their script so it applies to ZooKeeper project. The dashboard is now up and a Jenkins job is running on a daily base to monitor our builds and pick up flaky tests. I hope this dashboard can help increase the visibility and raise awareness of the quality of unit tests, and also help developers track and diagnose failures. Any feedback will be appreciated, and of course, contributions are very welcome. -- Cheers Michael.
