Been using Jest testing for web applications for almost 6 months and one thing that i´ve noticed on the web was the lack of a well structured tutorial about software testing and more specifically Jest Testing. So thank you Dave for the amazing content. Looking forward for a further chapters of this educational content.
Wow, I can't express how excited I am to see you've started a testing tutorial series! 🙌 I've been looking forward to learning more about testing for quite a while, and your videos are just what I needed.
Hello my friend, I don't do testing very often due to very strict deadlines, but it's always good to do so, 8:30 since we're passing an empty string to the join method no commas will be created, on the other hand, passing nothing(undefined) will add commas, Thanks Dave!
After a one year programming break, I really needed this playlist. I already knew all of them, but this was the best refresher I needed. Clean, short and very easy to understand. Please keep up the good work and continue making youtube videos!!!
Thank you so much. I have no words to appreciate the way you teach. word.toLowerCase().split('').reverse().join('') won't include the commas. So we won't need the replaceAll part. I know you know this, but you just came up with a quick solution. Mentioned it for the viewers.
I've a request sir please teach us how to test the api via jest I did the testing via jest for my express api but still have some confusion in stubs and mocks especially how we can test the api in the mvc structure like where our controller is interacting with services huge request
I just started testing for an e-commerce web app created with next js and typescript i had hard time configuring jest and typescript for unit and component testing but setup cypress pretty easily i hope this video help me understand jest and testing better thank you Dave for great content
Oh thank you for this series. I can't wait for you to get to the advanced testing such as making network requests, redux , axios interceptors and others.....I'm watching every testing video you are making....
Awesome intro to unit testing with jest. We use jest extensively at my job. This is a great way to get back to basics, understand how jest integrates with npm, and how to use it to write better code!
I am sure you get a million requests for topics, but could you please do a data structures and algos course? Basic linked lists, trees and graphs, big O, recursion etc. Your explanations are so in depth and helpful. I would love to see a dsa playlist at some point. Forgive me if you have this and I just have not found it yet.
Seriously, Dave! Thank you so much for doing this! Your channel as really helped me grow and progress within my journey! I've been trying to find some content creator that would create content solely for JEST! Thank you so much!
Thanks Dave, you've really helped on my Javascript journey i do really appreciate... I wish you could talk about getting a job, cause i feel I've been writing codes for myself, but all same thanks alot
I am so happy that you started doing the test series!! Could I request a content about call by reference vs call by value vs call by sharing? It's quite confusing since it works differently in other languages.
Thanks a lot for starting this series ❤, I can't thank you enough for this series as there almost no good tutorials around testing for web devs, I don't know much about testing yet, but it would be helpful if you could also teach e2e testing, basically enough about testing that is expected from a web developer.
Hello Dave, thank you for providing such amazing content. I have recently begun learning how to write tests for web applications and have started using Vitest as my testing framework. Do you think this is a good choice for testing?
Thanks, awesome tutorial! To me one of the issues ist the frontend, responsiveness and such things. That cannot be done with jest, right? Selenium or others?
You're welcome! Yes, you're looking at the UI there. Possible automation but devs also use tools like Browserstack to visually look at different devices, too.
Hey @Dave, Could you please create one Next.Js 13 Project using material UI on server side including the state management(redux for example) in Next app ?
I don't understand how testing libraries work behind the scenes so am like...... What's the point? How about just auto generating all possible inputs and supply to a function and watch the output/returned value? This jest testing appears to run a test using just one value so I don't see the point. But before I blab plenty of nonsense, let me research more about it. Thanks though!
Thanks for the tutorial. Why is this so slow though? It seems every new test adds about a second despite functions being super simple. In a large codebase this would be a nightmare. I don't really have experience testing JS but with Python (pytest) this would take milliseconds.
I can't focus on programming becouse i think only about money and how powerful it will make me! How to forget about a lot of money and start focusing on work?

How do I use jest with my crud methods?
Basically I want to test my crud methods

Much needed video , please cover unit testing , integration testing, End to end testing , React test library , Cypress
Didn't see that comming.
Excited for this series
pls, continue this. thank you again, Dave.

i hope this video help me understand jest and testing better
thank you Dave for great content
Cannot wait to see the content about cypress vs jest, and when we need to use them. Lovely.
Thanks Dave💯 Pure Gold!
Sir please make a video on how to test the react component which includes redux, custom hooks with mock api...I mean to test complex react components
Oh thank you for this series. I can't wait for you to get to the advanced testing such as making network requests, redux , axios interceptors and others.....I'm watching every testing video you are making....

Great video, I like how you use non trival examples and work in clean code principles.
Real nice! Thanks. I will add the tests when the strings are null or undefined.
Seriously, Dave! Thank you so much for doing this! Your channel as really helped me grow and progress within my journey! I've been trying to find some content creator that would create content solely for JEST! Thank you so much!
I have just finished a 3 hours long Cypress tutorial with E2E and Component testing. Let's see what Jest brings us =)) Thank you Dave!
nice intro to jest thank you, excited to integrate this into my Next.js app
Thanks Dave, you've really helped on my Javascript journey i do really appreciate... I wish you could talk about getting a job, cause i feel I've been writing codes for myself, but all same thanks alot
So excited! Thank you sir! Will definitely be sharing on my LinkedIn once done with mine!
Great topic 🎉
Thanks Dave
Amazing, I need to wrote whole bunch of test in work. Really appreciate your work
That was a good simple intro. Thank you.

Fantastic tutorial! Thank you so much! 💛
Thanks for this great lesson hope we see react and typeScript tests soon
Thank you for the amazing content Dave. The timing is perfect.
Hello Dave, thank you for providing such amazing content. I have recently begun learning how to write tests for web applications and have started using Vitest as my testing framework. Do you think this is a good choice for testing?
Nice thumbnail 😂
Really waiting for the videos
thank you, simple and to the point :)
Thanks Dave. Do you plan to do any DevOps videos for aws in future?
I'm definitely interested in doing that. I haven't had many requests for it, but it might still be good.
Really appreciate your work 🙌
Excellent video, thank you very much!!!
Nice explanation, thank you 😁
Thanks Dave, very clear explanation, I hope you'll continue this theme and also cover RTL.
Thanks, will do!
This was amazing, thank you so much!
thanks dave :) You're great! Will u continue this series. And will it come with nextjs or react. It would be perfect.
was really hoping this would be with nodes new internal testing library since it's gonna be available out of experimental with node 20
looking forward the next, please update Dave, please!
please please please, we need a full course
Is this a new playlist? Will you create more about it?
To avoid wrong autocompletion, you can press the escape key and continue typing
Thanks - yeah, I kept forgetting it was going to autocomplete what I didn't want. I don't always look while I'm typing lol.
you don't need replaceAll(',','') already join with empty string will concat all string with an empty string
thanks , now i am pro unit tester😂😂
Thanks, awesome tutorial! To me one of the issues ist the frontend, responsiveness and such things. That cannot be done with jest, right? Selenium or others?
You're welcome! Yes, you're looking at the UI there. Possible automation but devs also use tools like Browserstack to visually look at different devices, too.
But is possibile to show the output on the browser? Like Jasmine?
Hey @Dave,
Could you please create one Next.Js 13 Project using material UI on server side including the state management(redux for example) in Next app ?
Sir I have learned HTML ,CSS and Java Script please suggest me what I will have to read to become frontend developer.
Link to my web dev roadmap in the description 😀
for coverage, even if I dont write a test for reverseString, it still shows a 100% coverage
I mean, i just want to test my crud methods and i can't find how to do that
in react? cypress, react-testing-library???

Welcome - several reasons for the first run slowness here: www.google.com/search?q=why+is+jest+slow
Perfect thumbnail 🤣
thanks

thx
boss!
You would better not have names collisions (like sum is both function and file name) in toutorial purposes - it will mix up newbies

Please vitest
only girlymen write tests to check their code
'Hellert ,
Im here revising the video before beginning the testing with typescript video
