A simple @Rule that adds retrying logic to any JUnit 4 tests.
Install via JitPack. Instructions available here
In your test's class, add the RetryRule as a test rule, by creating
an instance of it as a public field, annotated with @Rule.
@Rule public final RetryRule retry = new RetryRule();Then, for any test that needs to implement retrying logic, annotate
the method with @Retry. Optional parameters on this annotation let
you change defaults such as the number of retries, the timeout length,
etc.
@Test
@Retry(times = 5) // runs test up to 5 times, instead of the default 3 times
public void myFlakyTest throws Exception {
obj.doUnreliableThing();
}Any test that still fails after its maximum number of tries will throw
a RetryException, which also contains an array of all of the exceptions
that were thrown by each attempt to run this test-case.
