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.
i agree, most of the youtuber prefers to keep their videos short on small topics, but he keeps his videos long and explains in better way... that is why I prefer him over any other coders or youtubers.
in my country, there's an old saying for people with good explanations, "they give you the soup straight to your mouth with a spoon.". This is what are you actually doing I mean a very simplified explanation that even a naive would understand. Thanks for the effort and time you put in those tutorials, I wouldn't have got any of this without them.
Corey, I took 3 C/C++ classes at UCSD Extension a few years ago and recieved 3 A's from 2 of the toughest professors at the University. I've watched a dozen of your Python videos and you are even better at teaching programming.
am 17 and i think if somehow i manged to make a good career in this field, its all goes upto u sir.... and i wnna say that , cuz ain't able to give u any fund but i always watch the ad till the end..even if its 2 min long.. GOD BLESS U SIR !!!!!!
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.
Bro, thank you so much. I am a python beginner and these tests were just giving me headaches. After watching this? I am not so uneducated anymore. Thank you and keep up the good work.
What kind of losers would dislike this video? Corey you are a time saver. Thanks for sharing with us the fruit of your hard work. You are one of the reasons why I am able to crack interviews and also deliver quality code at my work. Thank you once again.
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..!
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
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.
I have already watched many videos on the internet and going through various online courses (paid ones too), and I must say this channel has the best Python videos, from beginner to advanced topics. Thank you very much!
Once I read if I can explain things in a very simple way, it means I am the master of it. Totally true. I hope not to forget to donate when I get a job.
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.
I'm a data scientist, but some of my software engineer colleagues have encouraged me to check out testing. Thanks for the video, you've broken it down in a way that's both enjoyable and easy to follow!
THank you @Corey.. I was struggeling to understand the very basics.. It really helped me to get on my new work.. Thanks a lot for making the community a better place!!!
Thanks you so much. I'm from Taiwan and still new to programming but learned a lot from you. If one day I could be as good as you, I also want to share all my skills and knowledge to other people as you did. Hope we all can make the world a bit warmer and nicer :)
Finally found my way into my first job in software and your videos have been recommended and instrumental in pulling back so many curtains. Thank you for the clear and informative videos, you're crushing it.
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.
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
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.
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.
Really great video! I have been using unit test a little, but introducing mocking and proper use of teardowns and class methods really gave me a whole new perspective. Really informative stuff.
I gotta say that you just got a new fan, follower! man, I just love your videos and your approach! amazing! thank you so much for such incredible content!
Coming from embedded development this was a new way of testing for me. Normally we would just run stuff on our test rigs but our code base per product wasn't as massive as what I am working on now (cars). Thanks for explaining it so well.
Thank you so much. This is such a brilliant tutorial. As a beginner to programming struggling to understand what tests are and why they even matter, your video really helped me get more than just a conceptual understanding. Really appreciate you taking the time for such a detailed video.
"You don't have to be an expert at tests." True. I find that the most valuable test is the first one, because it gets the ball rolling and lets you have some idea that automated builds are running, not just "compi9ling."
I think this is the first time I managed to get through a 30 min+ programming tech tutorial without having to take a break. You've just earned yourself a new subscriber. ;) Any tutorials on Selenium?
Awesome content. All of it, but I have really enjoyed in particular your bs4, json, and regex videos. Really looking forward to any Selenium or phantomJS content that may come in the future.
6 years in, and this vid is still at its best. Thank you Corey. You're awesome
The best place to learn python! videos like these add value to internet :-)
Hey I have a doubt why do we use method why not directly use assertEqual in the class without creating a method and using self
The best place to *start* learning python. Go read the docs now!
Indeed

Thanks Corey. One of the best explanations of mocking with unittest I have found :)
This is a great tutorial for unit tests. Mock objects starts at 30:43
I came back an used this link to find about mocks, Thank you past me!
Very helpful video, big thank you. I wasn't able to figure it out from documentation alone.
Really glad to have come accross this tutorial, subscribed!
Best video that I've ever seen about unittest
Did you just explain dunder in one sentence? I love you.
Short intro and straight to the thing. Well prepared, simple yet clear demonstrative examples. Great video, thx man!
This is one of the clearest presentation of Python (and pytest) I've every scene. Truly demystified a lot of it.
