Tsz Wo Nicholas Sze commented on RATIS-247:
-------------------------------------------

I have manually verified the JUnitRunListener by the test below.  It works 
well.  The thread dump can be found in the output.
{code}
@Test(timeout = 1)
public void testTimeout() throws Exception {
 Thread.sleep(1000);
}
{code}

> Some unit tests fail with timeout occasionally.  It would be great if it 
> dumps all threads when test timeout.
