JavaScript Testing - Mocking Async Code

Testing async JavaScript code or testing JS dependencies in general can be difficult. But "mocking" is a technique that can easily be implemented with Jest to make JavaScript testing a breeze again.

Testing is something you don't quite often find in most tutorials. Thanks for tackling this all important topic.

As always, you're the best tutor! Note: Max, when I open the link to the github to clone the code I got the previous video's code and not the one you teach here about mock. Not sure if it's only for me but please take a look so it will help others to easily code along.
Again, thanks a lot as usual for your wonderful tutorial.

Honestly the best explanation I could find on mocking. Thank you :)

I would really love a full course on testing with jest, enzyme and react testing library

Hey Max, you should add Unit Test into your Udemy Angular 2+ Courses to make it even more great. Love your works btw.

Hi, Max
Thank you for this video.
This is the best explanation of moking with jest, that I found!
I was not familiar with using moke functions, before watching this video, but now I can use this great thing for testing methods in my project)

Excellent video.
I've been using mocha/chia/nyc for years.
I think i'll try jest.

Max, the starting code you linked in the description is actually the code from the PREVIOUS video. I cannot seem to find anywhere the starting code for this video. Can you please include it? Thanks for another great tutorial!

[khalidelgazzar]

Great video, though Concepts are more advanced than the previous video

[twinstars]

A very nice tutorial on javascript testing. Thank you.

[ivanaleksandrov]

Max, you nailed the technical stuff, how about a video or even better a series on being a freelance developer?

[dariogabalec]

best explanation about Mocking on the internet, thanks! 😀

[driden]

Hahaha, Max always pops up when searching for something I need <3

[dmitrik]

Is this possible to do in angular with is configured to use jest? Is it possible to override a function manually like in the video?

thank you for the tutorial. Please make more videos in testing.
