test_turtle.TestRawTurtle.test_clone(self): assert the last item in the items list of the cloned turtle is correct. more specifically, the item should be the same as the currentLineItem of the cloned turtle. also, the currentLineItem of the original turtle should not be in the items list of the cloned turtle. test_turtle.TestRawTurtle.setUp(self): skip test if the RawTurtle cannot be initialized because tk/tcl is not supported
