How to Test Raising and Not Raising an Exception Using Only One Function in pytest

In this pytest tutorial, I'll show you how to write a single test function that tests if an exception is raised or not.

First, we implement a division function, which we want to test.

Secondly, pytest's raises function is used to test that a specific exception is raised.

Lastly, I'll show you how you can use a null context in combination with the parametrize marker to test whether an exception is raised or not in only one function!
