different behavior when running with jUnit

Hi

Have a line in the groovy script test step that runs fine while within the soapUI environment. But when I run the test case in jUnit. I am getting a null error.

The line that is in question is

def project= testRunner.getTestCase().getTestSuite().getProject().getWorkspace().getProjectByName("EssTest");


It works fine until I try to run this in a junit testing. Got the following error

09:55:52,960 ERROR [SoapUI] An error occured [Cannot invoke method getProjectByName() on null object], see error log for details
