OCUnit test for protocols/callbacks/delegate in Objective-C

Using OCUnit, is there a way to test delegate protocols?

I'm trying this, which doesn't work.

-(void) testSomeObjDelegate {
  SomeObj obj = [[SomeObj alloc] initWithDelegate:self];
  [obj executeMethod];
}
-(void) someObjDelegateMethod {
  //test something here
}

I'm going to try calling the obj method on a different thread and have the test sleep until the delegate is called. It just seems like there should be an easier way to test this.
