This was by far the best video I've seen on pytest and mock. Thank you! Just implemented a ton of these in my tests which cut the code by like 75% and allowed me to do a complete end-to-end test of the platform vs just a few of the functions.

BEST BEST BEST EXPLANATION. Finally I understood UT's thank you !!!

This is the best learning video on pytests and mock in the history of python content out there, I am very lucky to have discovered this gem. Please make more such videos, also on AI with Python.

So far I found this tutorial series useful. Instead of magical things, I am learning logical things.

[SravanKumarduggirala]

Perfectly covered all the topics brother....

[PrantikPanja]

Thanks Man ! This is the best explanation of Mock I have found so far. You have reduced my stress a lot.

[iwswordpress]

Excellent explanation! One of the best if not the best I have come across. Thanks :)

[propadovicnenad]

This is an excellent and to the point explanation. Thanks a lot!

Thanks, But the title said pytest, I thought you are going to mock calls with pytest. But this tutorial is using the unit tests to mock, that is not the expectation from the title.

Cant thank you enough for this exceptional video. You covered so many scenarios. I was also working on a complex test where I needed to mock some objects which had other functions associated with it that I needed to mock. Using all the learning from your video and after watching is 2 3 times I was able to do that difficult task. I am new to testing too. Great man.

This is video is super helpful! After a lot of exploration about mock and patch, I came across this video and make the job easy for a data science person who is new to unittest! :) :) Thanks a lot!!

Hi Nikhil,
This playlist is really good, could you please extend this playlist and include how configuring and use tox for automation in testing. Just wanna know if there is any unit testing framework design specific to a machine learning.

[TJKhara]

Excellent video. You are a talented teacher. I am glad I found your video. Many thanks for taking the time to create these.

[simplyviki]

Thanks, I need to create pytest for a python program where I am connecting to postgres db and running select query. How to mock a db connection and how to mock other things like query or tables etc. I am confused about the approach to take to test

[kunallohar]

What you did at @13.38 to load the code of mock.py

[kdecibel]

But you are using the unittest library not fully pytest

[totiqauan]

Can't we mock the return_value from get_ip() directly instead of mocking things within the function? For example if I just use the output of get_ip() elsewhere. Is there a difference between the two approaches?

[shubhisrivastava]

Great playlist, is there a way to unit test nested functions using pytest?

[TheSandyfamily]

Can you upload video on how we can mock functions called outside a method.. in lambda
