From 2d4d64481b397852a21813defe40ff70c3e79718 Mon Sep 17 00:00:00 2001 From: Matthias Sohn Date: Wed, 25 May 2016 01:07:18 +0200 Subject: Add a RepeatRule to help repeating flaky tests A JUnit TestRule which enables to run the same JUnit test repeatedly. This may help to identify the root cause why a flaky tests which succeed most often does fail sometimes. Add the RepeatRule to the test class containing the test to be repeated: public class MyTest { @Rule public RepeatRule repeatRule = new RepeatRule(); ... } and annotate the test to be repeated with the @Repeat(n=) annotation: @Test @Repeat(n = 100) public void test() { ... } then this test will be repeated 100 times. If any test execution fails test repetition will be stopped.
