Get all test step result of a test case

Get all test step result of a test case , I have tried the following code for achieving it

for( r in testRunner.results )
log.info( "TestStep " + r.testStep.name + " finished with status " + r.status )


But this code does not get me any result.

But came to know from the forums that this code is working for many folks, how to implement this piece of code.

Thanks
