问题 I'm using the ExpandoMetaClass to make a service always return success in an integration test but I would like to have one test that actually fails. Example use of ExpandoMetaClass: static { ExpandoMetaClass someService = new ExpandoMetaClass(Object, false) someService.accessAnotherSystem = { return 'success' } someService.initialize() SomeService.metaClass = someService } Note: currently the service isn't defined for the controller but since it's a spring bean referencing the class named
