Good example, but found a little bug if you specify Repeat(3) its actually called 4 times. Fixed it with

runLeaf(statement, desc, notifier);

There are two bugs in your runChild() code.

1)In the case of @Repeat method it will run one extra time too many. The code will first run repeatedly and then it will run on more time runChild().

2) In the case where @Repeat and @Ignore are both on the method, the runChild will also run, because the if statement will be false.

I rewrote the runChild() as:

@Override
protected void runChild(final FrameworkMethod method, RunNotifier notifier) {
Description description = describeChild(method);

if (method.getAnnotation(Repeat.class) != null) {

if (method.getAnnotation(Ignore.class) == null) {
runRepeatedly(methodBlock(method), description, notifier);
}
return;
}

super.runChild(method, notifier);
}

Very useful code, thanks!
How can I change the code so that before each test the method setUp runs and the method tearDown runs after each test?

I agree, but the code above is mostly a template or a code sample.
The way I use it usually is for example:
Add an annotation that gets a directory as an input (the directory includes sample inputs for test).
In the test, list all files in the directory, and run the test each time on a different input file (each test will display the test file in the JUnit window).
This way you can see directly which files fail the tests.

Incidently I have to say that although the above is a cool JUnit extension by itself, the whole premise of unit tests that "sometimes fail" is flawed at best, and useless at worst - in my humble oppinion. Presumably you have no idea how often the test fails, so there is no guarantee that your CI server will ever execute the test enough times to observe the problem. You might as well not have the test at all.

The correct approach is to identify the cause of the failure and write a test for that. A test that either works, or fails - each and every time :-)

2012-07-05T15:51:10.561+03:00

I have a situation where two frameworks are providing test runners, and I'd like to use both - somehow. Frankly I don't know how to approach this problem, as I am by no means an expert in JUnit.

How do I create a "wrapper" that somehow provides me with the features of both runners?

2012-05-03T09:47:10.001+03:00

when you click on a test in junit view, it does not take you to the failed line, this is because the name of the test harms parsing.
replace:
description.addChild(Description.createTestDescription(
getTestClass().getJavaClass(),
"[" + i + "] " + testName(method)));
with:
description.addChild(Description.createTestDescription(
getTestClass().getJavaClass(),
testName(method) "[" + i + "] "));

and it will work as expected

Hey Rajesh. You can't run with 2 runners. They must work as wrappers. Its not too hard to do this though.

Can Extended Runner work with multiple runners? I am having a Suite Filter Runner. This would be additional Runner . Can I run test suites with Two runners?

With JUnit 4.9b3, the most recent beta, it doesn't seem to work either. I get an error from FilterRequest:

Definitely seems like something that should be built-in in the JUnit framework.
