Method Details

isSameParameterizedCluster

protected static boolean isSameParameterizedCluster(Class<?> registryImpl,
 int numHedgedReqs)

JUnit does not provide an easy way to run a hook after each parameterized run. Without that there is no easy way to restart the test cluster after each parameterized run. Annotation BeforeParam does not work either because it runs before parameterization and hence does not have access to the test parameters (which is weird). This *hack* checks if the current instance of test cluster configuration has the passed parameterized configs. In such a case, we can just reuse the cluster for test and do not need to initialize from scratch. While this is a hack, it saves a ton of time for the full test and de-flakes it.
