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.
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.
Right, it’s hard to find relevant TH-cam 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
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!!!
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!
Thank you very much. I would also like to see a video on testing sign-in with Google and using some kind of authentication. I also want to see more videos on React or Next.js projects with MySQL
Who polices the police? Who tests the tests? If you know what to expect, why not certify components, something does not sit well with me about testing? Maybe because I don't fully understand it.
good job man, more testing video with this library is appreciated! :) Can you do also a video with react and cypress? you suggest this library for testing?
i don't understand every you just said. I don't even know where to start learning the fundamentals. INTERNET HAS SO MANY SOURCES but I'm overwhelm where should i choose.
really helped me out with this one thanks...btw, do you do any BDD by any chance...something with Cucumberjs and gherkin would really be much appreciated...thanks for all your vids
hi, i got error like could not find react-redux context value; please ensure the component is wrapped in a but i also wrapped by provider within store and i change old to latest version please gave me a any solution
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.
Thanks for the good content, I have a question about using Jest on Nodejs app, after a long search I found that I have to use babel as a compiler (babel-jest) to be able to work with ES6 syntax. are there a way to deal with it the same way you did here for react app? Thanks a lot 🙌
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!
hey, i have a very often crucial question. i have to test a component which gets a setState function as a prop, how can i mock this setState function while testing the component?
a really great tutorial, thank you so much! I was able to follow and understand up to 36th minute. Why do we create a __mocks__ directory and an axios.js file in it and not use them?
Extraordinary video, all the content is very useful because you explain in a perfect way all the concepts of testing. It would be great to see other videos on this important topic. Immensely grateful.
Wow!! This is world class content 👑. Looking forward to more testing tutorials. Integrated testing 🔥 Redux 🔥 Node backend 🔥 But it is just a wish 😭😭😭
The testing library gets updated/refreshed so frequently, your video was the most relevant and straightforward. Thanks so much!

You made the whole process look extremely simple. Great tutorial, thanks!
Tdd was always weird to me but after this tutorial it makes sense. Thank you so much.
