Ignore tests until a certain date.

This allows you to write an acceptance/integration test before implementing a feature, and integrate it into your codebase before the implementation is complete.

@Rule
IgnoreUntilRule rule = new IgnoreUntilRule();

@IgnoreUntil("2014-10-30")
@Test
public void example_test_ignored_until_a_date() {

}

Quarantine non-deterministic tests

@Rule QuarantineRule rule = new QuarantineRule();

@NonDeterministic(retries=3)
public void some_sporadically_failing_test() {

}

QuarantineRule supports a functional interface called QuarantineRuleLogger as a constructor argument for additional logging capabilities. For example, we email ourselves failures so it's harder to ignore.

@Rule QuarantineRule rule = new QuarantineRule(msg -> System.err.println(msg));

Make sure tests pass reliably

We use this to diagnose tests as being non-deterministic. To run each test 10 times:

@Rule ReliabilityRule rule = new ReliabilityRule(10);
