Pytest provides a clean and concise syntax for writing tests. If you install the spy into foo (the class, instead of the instance) then it works. Here, we spy on the info method of the logger to ensure it is called with the correct.
What happens (iirc) is that special methods are called via descriptors and bypass instance lookup;
To execute a test from inside a class in pytest, you can simply define the test methods inside the class and then use the pytest module to run the tests. Learn how to set up and run automated tests with. The mocker.spy object acts exactly like the original method in all cases, except the spy also tracks function/method calls, return values and exceptions raised. To mock a class method, you first need to.
To test class methods, we can define test functions and use the classmethod fixture provided by pytest. The spy() method keeps track of how a real method is called without altering its behavior. All you need to do to test a class method is instantiate that class, and call the method on that instance: This guide will help you understand how to effectively use pytest to spy on the return values of methods within inner classes.

Plugins add extra features to pytest.
Following is the code for the unit test: One test function can now check multiple cases efficiently. I am trying to figure out how to know if a method of class is being called inside a method. I was playing around with the spy feature and realized it will happily create a spy object when referencing a class attribute:
Mocking is a technique that allows you to isolate a piece of code being tested from its dependencies so that the test can focus on the code under test in isolation. In pytest, you can mock a class method called inside another class by using the patch decorator from the unittest.mock module. I'm not sure if it's even possible after browsing through the source code.
