Chance Makes Good Tests
summary
A bug-hunting workflow for Java unit tests using a randomized-testing framework that injects and logs the exact random seed so failures can be reproduced. The framework randomizes nodes, shards, replicas, index names, locales (including rare ones like Azerbaijan), time zones and test order, detects stray threads, and lets you annotate or force values; implementation details cover seed injection, a property to pick or randomize locale, and the limitation that it works with JUnit4 only.
