PropertyMock
- PropertyMock(*args, **kwargs)
A mock intended to be used as a property, or other descriptor, on a class. `PropertyMock` provides `__get__` and `__set__` methods so you can specify a return value when it is fetched. Fetching a `PropertyMock` instance from an object calls the mock, with no args. Setting it calls the mock with the value being set.

>>> class Foo: ... @property ... def foo(self): ... return 'something' ... @foo.setter ... def foo(self, value): ... pass ... >>> with patch('__main__.Foo.foo', new_callable=PropertyMock) as mock_foo: ... mock_foo.return_value = 'mockity-mock' ... this_foo = Foo() ... print(this_foo.foo) ... this_foo.foo = 6 ... mockity-mock >>> mock_foo.mock_calls [call(), call(6)]
