Today I'm starting a new series of articles about a topic that does not get a lot of coverage: how to write Python unit tests. Unlike other testing tutorials, I'm going to focus on testing techniques more than o
When you’re writing code inPython, it’s important to make sure that your code works as expected. One of the best ways to do this is by using unit tests, which help you check if small parts (or units) of your code are working correctly. In this article, we will learn how to wr...
Write the test methods starting with the test keyword liketest_functionName(self)and use assert methods to verify the behavior of the code being tested. Run the commandpython -m unittest test_example.pyin the terminal or invoke the main method of unittest in the test file and runpython test_...
pytest is a powerful, feature-rich testing framework for Python that makes it easy to write simple and scalable test cases. It is widely used for unit testing, functional testing, and even complex test automation in Python projects. It is known for its simple syntax, rich test discovery capab...
function of an application works as intended. Whether you are testing a small feature or an entire system, writing effective test cases is crucial for the success of the project.In this guide, we’ll explore how to write test cases, the importance of doing so, and best practices to follow...

Pythonhas a reputation as being a simple language to work in, but that doesn’t always extend to the unit tests; some things are just really awkward to write tests for. Perhaps the function you’re testing requires you tomockout a bunch of things, or perhaps it outputs a complex data ...
Mocks are a crucial tool in the unit testing toolkit, but their overuse often leads to a series of unintended consequences: Tightly Coupled Tests: When tests rely heavily on mocks, they often become tightly coupled to the implementation details of the code. Even minor refactoring can break these...
A company brought me in to teach developers to write automated unit testing and someone is asking me a term loosely associated to the QA group. What gives?But in fact, this really just begs the question, “what is a test case?” And why might it vary depending on who write...
