Class RetryRule

  • All Implemented Interfaces:
    org.junit.rules.TestRule
    public class RetryRule
extends Object
implements org.junit.rules.TestRule
    A rule to retry failed tests for a fixed number of times.

    Add the RetryRule to your test class and annotate the class and/or tests with either RetryOnFailure or RetryOnException. If both the class and test are annotated, then only the latter annotation is taken into account. 

     @RetryOnFailure(times=1)
 public class YourTest {

     @Rule
     public RetryRule retryRule = new RetryRule();

     @Test
     public void yourTest() {
         // This will be retried 1 time (total runs 2) before failing the test.
         throw new Exception("Failing test");
     }

     @Test
     @RetryOnFailure(times=2)
     public void yourTest() {
         // This will be retried 2 time (total runs 3) before failing the test.
         throw new Exception("Failing test");
     }
 }
