This guy is great. A lot of times when watching videos, I have a question in my head that never gets answered. This guy guessed my questions, spoke them out loud and then answered them not once but twice.

Kudos for not leaving out important details.

Would like to see a pytest assertion that the proper error is thrown/raised.

Great introduction, thanks a lot. For a Python Newbie, that is very helpful.

That was a good tutorial, thank you.

The --cov flag didnt work for me until i manually installed cov with pip install pytest-cov. Otherwise, excellent tutorial with nice pace.

Really Great tutorial, I learned the concepts of applying TDD practically :)

This is the perfect tutorial. Now I feel comfortable about test driven development. Can you point me. @Chyld, can you point me to a great resource for learning the advance stuffs when it comes to test driven development with pytest?

Corey Hermanson on May 18, 2019

Thank you Chyld! This was a fantastic bite-sized intro to TDD. Excited to implement.

Great tutorials. It gives you the big picture of the unit testing concept by pytest in a short time. These tutorials will be the good choice if you don’t have enough time to study the pytest framework because it drives you to the important concepts that you need to start testing your code.

Thank you.

This was useful and perhaps this could be my first step into test driven development.
