For this post, I talk about mocking objects in Python. As a Rubyist, this one was initially confusing especially since I was not yet familiar with Python’s package import magic. Importing Packages and Objects (A Review) You need to understand this part before you can effectively mock objects in Python.


Mock functions allow you to test the links between code by erasing the actual implementation of a function, capturing calls to the function (and the parameters passed in those calls), capturing instances of constructor functions when instantiated with `new`, and allowing test-time configuration of return values.

Mock is a Python mocking and testing library. It has become a de facto standard and is now included in the Python standard library.. Lately I’ve had the chance to work on a fairly large code base built upon a service-oriented architecture.

When the mock object is called, we want it to be able to return some values. In our case, we want the mock object to return a value of 10. If we call the mock object with the arguments (1, 4, foo ='bar'), the result will be the value 10, which was defined as a return value. You can also raise exceptions inside mocks as follows:

So the value "mock_string" is duplicated, although if it changed in one place that does not necessarily mean it would change in all other places. What would you do about this? Either create a constant and use that in place of the duplicated key, or leave the value in place? We're conflicted.
