Extra newlines are removed at the end of non-shell files. If the file only has newlines after stripping other trailing whitespace, all are removed, as is done by patchcheck.py.

When mock function is called, set or use attributes:

self.called - increment call number even if no args, kwds passed.
|
|
self.args - capture positional arguments.
|
|
self.kwds - capture keyword arguments.
|
|
self.result - return or raise value set in __init__.
|
|
self.return_self - return self instead, to mock query class return.

Most common use will probably be to mock instance methods.
|
|
Given class instance, can set and delete as instance attribute.
|

Mock_tk.Var and Mbox_func are special variants of this.
