React Testing Tutorial with React Testing Library and Jest

[@corinapelichowski2950]

Right, it’s hard to find relevant KZbin tutorials because everything in the tech world is changing so fast and things get old too quickly. HOWEVER! This is the best React Testing tutorial I have come across so far. It’s relevant, to the point, and super easy to follow along. I highly recommend going to the git repo, downloading it, deleting the test file, and follow along. That way you can learn how to test without getting overwhelmed with learning the components too. 10/10

The testing library gets updated/refreshed so frequently, your video was the most relevant and straightforward. Thanks so much!

[@exequiel_hyan]

For those having issues with Axios in jest, put this in your package.json user the 'scripts' object: "test": "react-scripts test --transformIgnorePatterns \"node_modules/(?!axios)/\"", It worked for me, hope it works for you too.

[@wmv1990]

Excellent tutorial, love it, thanks Lama Dev. For anyone struggling with JEST intelli-sense not coming up in Visual Studio code.(automatic methods and variables suggestions popping up) Just add a file named ' jsconfig.json ' at root level i.e in your top project folder and paste below code in that file. { "typeAcquisition": { "include": [ "jest" ] } } Probably restart VS code to be sure it got embedded.

[@berkinakkaya981]

You made the whole process look extremely simple. Great tutorial, thanks!

[@Corntrop]

Tdd was always weird to me but after this tutorial it makes sense. Thank you so much.

[@ozzyfromspace]

Okay, while I'm riding the high of confidence you gave me about TDD, lemme start working on a react project with this approach :) . Thanks, Lama Dev!!

[@mD-mp8bb]

Entrance Song👍👍 I knew Jest and react testing library but I watched the course again.

[@luffymonkey6967]

Yes!!! Exactly the kind of video i was looking for and from an amazing channel that I like. Just started watching recently and your video tutorials are really good!

[@eprisrichardson678]

You always explain things in a way that even a kid could understand. This was very helpful. I'm using Mock Service Worker as recommended in the Testing Library docs, so I guess my mock API will be setup differently. I just have to figure that out. Thanks for the tutorial!!!

[@som_girl6702]

You’re a great teacher. Few minutes into your video, I understood testing without prior knowledge of JS testing

[@SimPwear84]

Wow!! This is world class content 👑. Looking forward to more testing tutorials. Integrated testing 🔥 Redux 🔥 Node backend 🔥 But it is just a wish 😭😭😭

[@dansalomon7112]

Awesome tutorial !👑

[@haciendadad]

GREAT Video!! Man, I HATE unit testing!!! Now I joined a new team and they assigned me to get the teams unit test coverage to be at least 85%. All our code is in React, so I am hoping that I can use this test library because it looks a lot more fun than the regular jest. And that Wallaby VS Code extension is awesome! I might even do some unit testing on the weekends? uh, maybe once or twice only. :-) Definitely subscribed and liked!! I really like everything about his testing style. Good pace, great examples! I hate super simple examples. And the length isn't too long, well done sir! #HatTip!

[@fichamann1527]

[@Leonavancini]

This help me a lot to understand how its works , its a very good tutorial and simple. All testing cases need to be very methodical right? This take me a lot of time to made it, now I understand why some companies don't have tested applications, BTW I don't know if I'm right but it's necessary to make a test to check if error message will visible in error case right? I wanna try to make it that test.
