Class RunUntilFailureRule

java.lang.Object

org.opendaylight.infrautils.testutils.RunUntilFailureRule

All Implemented Interfaces:

org.junit.rules.TestRule

public class RunUntilFailureRule
extends Object
implements org.junit.rules.TestRule

JUnit Rule which allows to keep running tests indefinitely.

This is useful to add locally, never commit, if you would like to keep running a "flaky" (sometimes passing, sometimes failing) test until it fails. Usage:

   public static  @ClassRule RunUntilFailureClassRule classRepeater = new RunUntilFailureClassRule();
   public  @Rule RunUntilFailureRule repeater = new RunUntilFailureRule(classRepeater);

    @Test ...

The two rules are necessary because a ClassRule alone cannot stop the test on a failure, and a normal Rule alone cannot keep running all @Test (it would indefinitely run only the first test). Alternatives to two rules would be to use a @RunWith with a custom TestRunner, or writing a test suite each time.
