Running a Test Case from groovy script

Hi Ole

I want to run a test case. For that I have coded the following. But, I get compilation error. Can you pl. help me

testRunner.getTestCase().getTestStepByName("Step getSessionid").run(testRunner, context);
       
println("Finished Executing:");
        List stepResult=testRunner.getResults()
    Iterator j=stepResult.iterator();
    while (j.hasNext())
  {
      TestStepResult result=(TestStepResult)j.next();
      println("result:"+result.getStatus())
  }

The error is in "TestStepResult result=(TestStepResult)j.next();"

Also can you explain me why is testrunner being passed as parameter in the run method?

Thanks
Anu
