Writing unit tests

Writing tests with pytest involves creating test functions that verify the functionality of your code. These test functions are executed by pytest and can be organized into test modules and test packages. In addition to test functions, pytest provides other testing features such as fixtures, parameterization, and mocking, which can help you write more robust and efficient tests.

In this section, we will cover the basics of writing tests with pytest, including creating test functions, using assertions to check for expected behavior, and organizing tests into test suites.

Now, let’s laser-focus on writing unit tests for a user registration component of an application.

Unit-testing user registration

Unit testing is a crucial part of the software development process. Unit testing unarguably allows developers to verify that their code works correctly and reliably, as stated earlier. One area where unit testing is particularly important is user registration...
