CPM error in test harness

Content

Hi All,

I have written a cpm script for incident create and update.While testing it, in setup function of test harness i am fetching an existing incident id. But it is giving the error 'Invalid ID:No such incident'. 
Is this the proper way to test or do need to create test object in the setup function?

Thanks

Puneet

	return; 
}
