Groovy assert called test step's result

 Hello,

I have a problem with groovy scripts when I call a testStep. I proceed as follows :

def TC; 
def async = false

TC = testRunner.testCase.testSuite.project.getTestSuiteByName(testSuite).getTestCaseByName(testcase)

TC.setPropertyValue("my_prop", my_value)
result = TC.run (context.getProperties(), async)      

log.info result.status

the logger indicates PASS

the problem is when I try to assert this status (which is an enum), assertion always fails

assert result.status == "PASS"  => fails
assert result.status == PASS  => not authorized

how could I do ?

thanks for any help

Alexandre
