11 When mock function is called, set or use attributes: 

12 self.called - increment call number even if no args, kwds passed. 

13 self.args - capture positional arguments. 

14 self.kwds - capture keyword arguments. 

15 self.result - return or raise value set in __init__. 

16 self.return_self - return self instead, to mock query class return. 

17 

18 Most common use will probably be to mock instance methods. 

19 Given class instance, can set and delete as instance attribute. 

20 Mock_tk.Var and Mbox_func are special variants of this.
