Python Tutorial: Unit Testing Your Code with the unittest Module

In this Python Programming Tutorial, we will be learning how to unit-test our code using the unittest module. Unit testing will allow you to be more comfortable with refactoring and knowing whether or not your updates broke any of your existing code. Unit testing is a must on any large projects and is used by all major companies. Not only that, but it will greatly improve your personal code as well. Let's get started.

[@hubertcombomarketing2693]

You're great Corey. With use of simple code editor You can explain complicated things. No greenscreen, no slides, just calm and pure explanations. English is a foreign language to me, but Your videos are so understandable, that this is not a problem. Once again thank You very much.

It was a really very good moment when I found this channel. Such good, clear and no-nonsense explanations.

[@elliria_home]

This is just plain glorious. If there's such a thing as falling in love with code, this has got to be it. I enjoyed every moment of it. You're amazing, Corey, and you did a wonderful job of very clearly explaining all of it. From where I sit, you created a masterpiece of art. It's simply amazing. Test-driven development, here I come.

[@BarbaraVreede]

I love the flow in your lectures; you usually respond exactly to the questions that pop up in my head. For instance: the print statements here were so very useful, this is exactly what I would do in trying to understand this on my own machine. You are an absolute life saver, Corey, thank you so much.

This is the most in depth unit testing tutorial I have seen. Very informative!

[@JayR98]

Those 40 min were absolutely worth it and cleared up the concept of unit tests, especially the last part about mocking was exactly what I needed!. Now I will be able to write some of the first-ever tests for my project, thanks a lot @Corey Schafer

Amazing Videos! They are so easy to follow and well thought out. I have had a few instances where the library versions you are using have changed and your explanation of what is going on has allowed me to work through the new syntax in the updated libraries. This one is helping me so much at work at the moment.

I made my first python project without implementing a test. Judging from my experience it was really rough, It took me a lot of late night sleep just to see if a feature works the way I intended. Now I am learning testing and trying to apply it in my current project. I hope I had learn testing earlier, before proceeding to create my project. The video uses unit test, while mine was pytest, but hoping the concepts I learn here is same to be applied in pytest. Appreciate videos like these are created for free to everyone.

Hey, thanks i am making an interpreter with Python and i wanted to write some tests for it. I was unaware of how to properly do python tests since i have never done them before, so watching this video cleared up a lot of doubts.

[@garybloomlaw]

Fantastic videos. I would add that the test cases can be spread across multiple classes. This allows you to group tests together so that you can make good use of setUp() and setUpClass(). For example, if you have multiple tests that require a database, you could group all those tests into a single class and have the setUpClass() method prepare the db. Tests that don't involve the db would go into other test classes. The larger the overall project, the more test classes you are likely to have.

[@gouthamanush]

I am looking at all of your videos and as your videos are old, I thought lot of comments must be old. But to my surprise I see lot of latest comments which indicate lot of people still following these videos. Cheers to you bro.! I am experienced in Python and really these are the most simple and clear videos I have ever seen.! Your examples are mostly real time scenarios and they are very simple so that everyone can understand. Keep up the good work..!

Hi Corey, yet again another excellent tutorial. With this invaluable lesson, I can finally de-clutter my scripts/classes from all those messy checking print statements all over the place. Also thoroughly enjoying the oop tuts for python. Classes and objects are finally making sense thanks to that series. Just one tiny observation, the 'else' in the monthly_schedule method is unnecessary (although, I imagine this may look clearer to many, even to myself), though it still works like this. Many thanks for all this work and commitment.

Nice now i have a guy I can check out if I am so unfamiliar with a topic that i don't really understand pythons documentation. Piece of advice to everybody: Don't ever thing videos like this are more then a brief introduction into a topic. They are crazy helpful but all they really do is give you a less frustrating way to grasp the basics without being very annoyed by pythons very own documentation. And for gods sake start using the python help function :D
