copied!<p>As for me writing custom runner more flexible solution. The solution that posted above (with code example) has two disadvantages:</p> <ol> <li>It won't retry test if it fails on the @BeforeClass stage; </li> <li>It calculating tests run a bit differently (when you have 3 retries, you will receive test Runs: 4, success 1 that might be confusing);</li> </ol> <p>That's why I prefer more approach with writing custom runner. And code of custom runner could be following:</p> <pre><code>import org.junit.Ignore; import org.junit.internal.AssumptionViolatedException; import org.junit.internal.runners.model.EachTestNotifier; import org.junit.runner.Description; import org.junit.runner.notification.RunNotifier; import org.junit.runner.notification.StoppedByUserException; import org.junit.runners.BlockJUnit4ClassRunner; import org.junit.runners.model.FrameworkMethod; import org.junit.runners.model.InitializationError; import org.junit.runners.model.Statement; public class RetryRunner extends BlockJUnit4ClassRunner { private final int retryCount = 100; private int failedAttempts = 0; public RetryRunner(Class<?> klass) throws InitializationError { super(klass); } @Override public void run(final RunNotifier notifier) { EachTestNotifier testNotifier = new EachTestNotifier(notifier, getDescription()); Statement statement = classBlock(notifier); try { statement.evaluate(); } catch (AssumptionViolatedException e) { testNotifier.fireTestIgnored(); } catch (StoppedByUserException e) { throw e; } catch (Throwable e) { retry(testNotifier, statement, e); } } @Override protected void runChild(final FrameworkMethod method, RunNotifier notifier) { Description description = describeChild(method); if (method.getAnnotation(Ignore.class) != null) { notifier.fireTestIgnored(description); } else { runTestUnit(methodBlock(method), description, notifier); } } /** * Runs a {@link Statement} that represents a leaf (aka atomic) test. */ protected final void runTestUnit(Statement statement, Description description, RunNotifier notifier) { EachTestNotifier eachNotifier = new EachTestNotifier(notifier, description); eachNotifier.fireTestStarted(); try { statement.evaluate(); } catch (AssumptionViolatedException e) { eachNotifier.addFailedAssumption(e); } catch (Throwable e) { retry(eachNotifier, statement, e); } finally { eachNotifier.fireTestFinished(); } } public void retry(EachTestNotifier notifier, Statement statement, Throwable currentThrowable) { Throwable caughtThrowable = currentThrowable; while (retryCount > failedAttempts) { try { statement.evaluate(); return; } catch (Throwable t) { failedAttempts++; caughtThrowable = t; } } notifier.addFailure(caughtThrowable); } } </code></pre>
