How to mock an object property in Python

mock-object-property.py

import mock

with mock.patch('path.to.ObjectClass.my_property', new_callable=mock.PropertyMock) as mock_my_property:
    mock_my_property.return_value = 'my value'

thanks!

Good one. Thanks!

Thank you!

This also works:

import mock

with mock.patch("...", new_callable=mock.PropertyMock, return_value="my value"):
    ...

Can someone please demonstrate how to do it in other forms? I.e. without a context manager

HI I am using the same thing . The property is getting mocked properly with the proper value that i have set , but when i call the method to test which uses this property , the actual property is getting called instead of this mock that i have created .

Can someone please demonstrate how to do it in other forms? I.e. without a context manager

there is one decorator method:

@patch("...", new_callable=mock.PropertyMock,return_value="some_value")
def test_fun(self, mock):
    pass

Cool. Thanks. It saved me hours.
