Good introduction to React Testing Library. Very clearly explained. I do have a few remarks though: 1. It wouldn't hurt to explain that we are using Jest as our testing environment and that the functions "test" and "expect" for example are Jest functions. 2. It is recommended to call queries like getBy... etc., on the screen method imported from the testing library rather than on the return value of render. This is recommended by the official docs. 3. It is recommended to use userEvent rather than fireEvent to trigger, well, user events. 4. It would help to explain the "Arrange" - "Act" - "Assert" testing methodology. 5. Regarding getByTestId - As already mentioned in another comment, it is recommended in the official docs to only use it if there is no other way, and there usually are alternatives.

Please keep posting more testing-related content. This is incredible and there isn't much testing-related videos out there!

Commeting so the algo helps this guy to get more viewers he deserves it.

Dude this is an awesome video! I've been trying to wrap my head around this all day and your video was the best introduction I found :)

Hello, this video deserves much more attention guys!

Your video deserves a lot more views! Damn, never been this hooked (no pun intended) on a long programming video.

I have seen your GraphQL course, React with Typescript course, Docker Course and now this!!! Can't thank you enough for such informative videos man!

You're so good! I've been hunting for a teacher who doesn't just 'do the code' but explains the why. 10/10 Keep it up

Best tutorial ive seen so far on tdd. Thank you for explaining everything

This is the best React test crash course on KZfaq. Keep up the good job.

Thanks for the effort you've put in. Hope this video gets the attention it deserves :)

Best hour and a half of my life! This video deserves so much more attention.

Great explanation Laith. I know everyone has their own way of doing things, but you really explained the concepts well

Bravo. I have seen a lot of your tutorials and they are compact and well explained. Thank you so much

Great tutorial. Especially for someone starting out with the React ecosystem. Can you make a video using React Typescript with context API, HOC and testing? Think that will tick a lot of viewers' boxes. That will basically be the full package. The way you describe everything is very clear and straight forward. Keep up the great work!!!

Yes, great stuff!! Impressed with your simple and lucid examples.

thank you for explaining RTL in such a simple way, really appreciate you efforts.

This is by far the best video on TDD. Great job!

Hey bro, awesome video! Very interesting and quickly to understand. Hope you make more videos about testing. Thanksss

I have many paid course that teach Unit Test on React. But this is by far the best tutorial that I have ever watched.

The is some very high quality crash course. Thank you very much for sharing knowledge with the community!

this is really good. finished in one sit and learnt a lot. thank you

Awesome video, so useful! thank you so much for this content. 10/10 explanation

Thank you for the wonderful crash course. Subscribed :)

very nice, man! I struggled a bit with this lib until I realized it's logic is something like cascading css lol. helped a lot! thanks

thanks, you put a lot of effort here, totally useful for me, great work!

The best React Testing crash course :) Keep it up!

Very good and engaging course! Keep up the good work @Laith Harb!

This is pure gold. Thanks for this..

Thanks alot. This is wonderfully explained! 👍🏻

Thank you very much for the tutorial, easy to follow and engaging. The only comment I have is that I got a few eslint warnings, I did manage to fix them all after I finish the video but it did confused me a bit, so explaining that possible scenario could happen at the beginning would be great

Every single time I need to know something, Laith Harb has an amazing and recent crash course covering exactly what I'm trying to learn.

thank you for the video! by far the best RTL tutorial imo. Can you also make a video showing testing with async actions?

This was an amazing, highly efficient crash course. Thank you so much!

Thank you for this video. It is very informative. It really help me to understand the concepts.

Fantastic video, thanks a lot!

Excellent video, thank you!

The first time I tried to understand TDD my brain cried, now things are clearer. try to make more videos on the subject, KZfaq content is lacking about unit tests in web components. this video helped me a lot, thanks.

Thanks for this video! It helped me a lot

Thanks. Been looking for a good TDD crash course in React for some time now

Thank you so much ❤️

Best react-testing tutorial. Would appreciate tutorial on testing async functions in react...

Hi, thanks for this video, so much value in here! I would like to ask how can I test a component that receives props/is connected, I just keep in getting that the app should be wrapped in a provider which it already is, so I don't know how to simulate that behavior. Thanks in advance.

Thank you so much

Awesome!

Very correct and verbouse guide. This is exactly what i have looked for. A great thanks! You are master of explanation! Like, subscribe, arigato.

best video around

you made my day bruh.

Hi, really helpful. What font are you using in the terminal and VScode?

thank you. In some cases we need state and props to be here in our tests. for that cases which way should we supposed to pass?

thanks for sharing your knowledge. 1:09:40 can be written in a simpler form : className={ counterValue >= 100 ? 'green' : counterValue

This was a great video! Very informative and well explained. I learned quite a bit outside of just the react testing library, by virtue of how you coded the counter. I'll be sure to check out your other react videos after this.

It's really helpful. You earned a sub from me.

tks bro!

Hi, I'm kina new to the TDD and i m trying to follow along. Not a blocking problem but i was wondering if there was an addon or something is missing in my configuration because when i geto to (26:60) component.G intellisense doesnt recognize all the available query. thanks in advance for you re time
