We’ve developed this to be able to run trusted methods as batch operations that were saved into database to be performed later on. The code is easy to understand reading its tests: Tests: Check out this file Code: import os import inspect import inspect class...

This is about Python Mocker features. In order to pass in a mock as a parameter to the SUT (subject under test) you might think of creating the mock using either, “mock()” method or “proxy(SomeClass)” method. They both yield mocks but they work...
