I'm five minutes in and I can already tell your videos are a freaking god-send. Plus your accent makes listening and comprehending as easy as it should be in your native tongue...even for this American ;)

Thank you so much, this tutorial was amazing. Every single concept broken down into small bite size parts to make it really easy to understand. Keep it up please!

Hey Ryan, I'm from Brazil, this course is amazing. Step by step everything explained and instructive, congratulations bro! Please keep creating content like this.

This is the best selenium tutorial on youtube! 👏👏👏 I hope it hits the number of views and likes it truly deserves.

Hello Ryan, this is a great tutorial on testing in the Mocha framework. Thank you so much for your hard work 🙏💗 I've been learning JavaScript for just a few months and this tutorial is VERY clear and understandable to follow. Great job 👍

Loved this tutorial, everything is well explained and you helped me understand some concepts and the reason behaind them. Keep bringing this kind of content!

Very helpful, professional and understandable video tutorial. I learned a lot in less than 3 hours and definitely I highly recommend.

this tutorial is astounding in my opinion, thanks for this marvelous course I was needing for some projects I need to automatize

i have read the comments and i am going to start watching right from today

Best tutorial i've ever seen on Selenium. Thank you so much! I only wish i could like this video second time!

Not only I can learn how to write tests, but also how to solve errors like ReferenceError: describe is not defined, No test files found: "test" or [ERR_REQUIRE_ESM], by using stackoverflow. Yes, I'm aware that these problems are not caused by You, it's just a part of experience. 10/10, it's the best tutorial on the YT Edit: And now I see that I just needed to watch another 10 minutes to find a solutions to my other problems, 11/10 tbh.

A good tutorial to get me going in the right direction. I had to add "await driver.manage().setTimeouts({implicit: 3000});" after the url call as it was too quick and not finding the elements

What a fantastic job, mate. Here from Brazil and that´s the best tutorial, just love

Thanks to Lambda Test for all this content, and thank you, Ryan, for share this with us.

Congratulations from Spain. A great tutorial, direct and easy. Thank you for this kind of videos for sharing your knowledge. You have a new subscriber!

Thanks a lot man for the tutorial, really, you make this so simple to understand that is easy to use directly into the code .

I learned a whole lot. I like how you teach (step by step), very clear. Keep publishing great classes. Thank you!

This is very helpful for beginners like me. As a token of appreciation, I didn't skip the ads :) Thank you very much Sir Ryan Howard and the team!

Hi Ryan ! This a very helpful Tutorial , appreciate your great job . Thank you so much for your hard work.👍

these videos were really useful, thanks a lot.

Helped me get started. Thanks a bunch!

Thank you! Big help!

For recent video viewer (up to 2024) change the require to import to avoid issues

You helped me a lot. Thank you,

Great video learnt a ton from it!!! You have an editing error right at the hour mark where you didn't cut out the failed takes. Again, loved the vid.

Thanks bro, This tutorial help me very much!

amazing work, very clear and instructive👏🏻 highly recomended 🙌🏻

Cheers mate, that helped a lot

Thank you so much for your invaluable tutorial! With your guidance, I've successfully developed real-world benchmarking for both WebAssembly (Wasm) and JavaScript (JS). Now, I'm eager to automate these benchmarks to facilitate comparisons between the two technologies. I'm particularly interested in leveraging the Lambda Test report for printing all the benchmark reports. Could you please advise if it's feasible to integrate and display all the reports in the Lambda Test report? like to print the performance and memory taken by both technologies.

Great contest. One interesting observation, how come sequential tests execution (19 sec) is taking lesser time than parallel tests execution (23 sec) using Mocha? Skip the video till 1:21:03 and see for yourself which is a bit confusing!

After running the parallel command "npm test" where test="mocha --no-timeouts -parallel" it only runs 1 js test successfully and the second test window remains open and does not navigate to the todo website. Any ideas what could be issue ?

Hello Ryan, I really liked your tutorials, These lessons helped me a lot to understand and adopt the new platform, however, if you could create another updated version of these tutorials for Windows OS, it would be lot helpful. Thank you

Coul I install npm webdriver-manager instead donwload the web drivers? its the same, isn't? Thanks

great video.. do you have tutorial for js implementation of cdp or bidi? network intercept or other examples would been great

Subscrited! Great tutorial, it's perfect!

Cool video!

Awesome tutorial. how can i make the test close the browser when gets a error? in my test it continues open.

Amazing ! But I guess quality of videos could be enhanced as it deals with coding and people have to seeeeeee.

isn't Mocha like something different from Selenium? Why aren't you using grids

Why use Javascript for Test Automation over Java? I think Java is more commonly used and more autocomplete e.g. you had to write require code selenium-webdriver. But in a IDE like Eclipse can autocomplete the require library lines

Awesome tutorial, have silly question: according to 42m, why I don't see anything I output in my terminal? Test execute but don't have any status anywhere

hello, thx for the tutorial, but I have an issu with firefox. When I type "node tests/firstTest.js" in the terminal, firefox only open for 1sec, I can't see what's going on, no error message, just the search bar being red (? I don't know why). I'm on Windows, and I have no error in the VS terminal either, just the indication of my driver and browser Path. I really don't know what to do...

@ryantestsstuff hi! I am stuck on the first part and not sure why When I add the tests and the first test file and run the code after writing the first assertion i got an error Applicable driver not found; attempting to install with Selenium Manager (Beta).... I followed all instructions but could have missed something. Also when I added Mocha, and removed the 'tests/*js' from npx mocha --no-timeouts 'tests/*js' command, it didnt find the test file! why? when i add the follwoing command it works npx mocha --no-timeouts 'tests/*js' .

great video, has anyone ever told you that you look like Tobey Macguire?

Hello Ryan, really it is good tutorial but i faced problem when i called node test/firstTest.js nothing happened please help me urgently i need to do that task

Hi igot error like this succses fully add on todo list: WebDriverError: Unauthorized, either Username or AccessKey is invalid.

Hello. I'm stuck at the beginning, when I first try to launch firefox using the command 'node tests/firstTest.js' nothing happens when I send it. I have already downloaded the browser and also put the gecko path as an environment variable =/

Hey Ryan, I installed Chai and when I run the test I get the following error. I did everything according to your example: Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/.../firstTest.js not supported. Instead change the require of chai.js in /Users/.../firstTest.js to a dynamic import() which is available in all CommonJS modules. at Object. (/Users/.../firstTest.js:3:14) { code: 'ERR_REQUIRE_ESM' } Node.js v20.10.0

It is always hard for me to set up mocha configuration on javascript it always gives me errors like that. Error: No test files found: "test", ReferenceError: describe is not defined. I searched it on StackOverflow but it does not make sense.

Greetings, my browser Chrome, closes a few seconds after executing the function example.

Mochawesome folder is not generated when using --parallel flag. Anything changed there ? It works when i remove the --parallel flag

This course was an eye-opening, since I've done automation in Cypress only, and once I saw how you included Mocha and Chai assertions it basically looks the same to me...So can you explain to me if there's difference in the code writing, between those two automation tools, meaning Cypress and Selenium?

Hi i have problem with running an example from your tutorian on lambda test cloud. Locally it was working fine. But after modufication of script from chapter 7 (adding cloud Lambda test) I receive an error after npm test in terminal "" 1 passing (6s) 1 failing 1) Uncaught error outside test suite: Uncaught ReferenceError: capabilities is not defined" Any idea whot might be wrong?

Good content.

Hello sir, how can I scroll up and down. Because some web page don't load all results, they load dynamically when you scroll down. So how can I able to scroll up and down. Please help

Thank you so much for the tutorial! it is great so far but for some reason the new browser window is not opening up for me. Can anyone help me get unstuck please.

At 8:16 you said that we needed to update the path. I use windows and I went to the Environment Variables, but I am not sure what to look for exactly in there. Can you please help me figure that part out. Because when I tried doing the first test example in my VSCode, it says, "code: 'MODULE NOT FOUND',"

Is there anyone have the same my error when do chai assertion like this: "[ERR_REQUIRE_ESM]" , I need some help, please ! :)

How to run the selenium code in the html page with the invoke of a button. You told to run from the terminal. It is fine. Please tell me how to run it from the html page with the click of a button.

Is this posted somewhere else in better quality? 720p is terrible.

Your font size too small

very nice tutorial, but my ears are done, sometimes the sound is so loud I had to take my headphones down, sometimes I cant hear a thing

Great tutorial, but the voice is a little bit bad.

Nice tutorial. But your identation style confuses beginners.

I don't understand what was the need to keep the drum music in the background, its so annoying.

not helpful for windows at all.

My name is Ryan, I'm a robot.

Hi Ryan. Thank you for such insightful Tutorial. Can you please help me here?

hello thank you for your very good toturial. 😍 in section 6 your path for customizeDir is under the camera layer and not defined.🥲
