Introduction To Testing In JavaScript With Jest

[@drchrisntsako1339]

I'm someone who don't comment on videos but whenever I search for a video and see yours, I always choose you. you are the best man

[@jbruell94]

1000% agree.

[@deansprivatearchive]

This is a developer that truly knows what he's talking about, nonstop, in facts, and fast - short and simple, bite-sized tips to all development. Master branch, honestly.

Nope, he's a normal dev just like us. He just has the power of editing. He got a video on that.

[@deansprivatearchive]

​@ I know, that's not what I'm saying - No matter how much debugging he cuts out, the coding and aesthetics themselves are made by a developer that truly knows what he's talking about.

[@juanbomfim22]

@@deansprivatearchive I agree. And what reinforces it is his incredible diction

[@gainz6180]

@whats the name/link of that video?

[@hetroxity]

Kyle bro .. i love how you talk smoothly and going step by step without hurry..

[@tracynnnn]

Notes - test script: "jest --coverage" will detail what's being tested and what's not - Unit tests test the smallest part of your code - toBe() vs toEqual()

[@chickenchoclates1971]

i love you mate...

[@brunoichbinfdp]

thanlks a million times

[@mauricioviera6]

Thanks. I'm going through a job interview and they asked me to run unit tests, so this is really helpful as a start. Really appreciate it

[@aurumstinger4479]

Did everything go well??

[@JamesQQuick]

Using this as a first intro to jest for me. Thanks Kyle!!

[@ANDREPEIXOTO1]

Me too. Thanks, Kyle! I'll have a technical interview covering jest and this video was helpful. Now I'm going to dive deeper into it.

[@JohnMitchellCalif]

I'm a testing expert, and I congratulate you. Your explanation is very clear and understandable! Subscribed.

[@ВладимирНетот]

so why the expert like you is watching tutorial for beginners?

[@fragileglass9622]

That's awesome. I was just searching on Udemy for a Jest testing course when this popped up. Weird. I'd would really like to see more testing or production deployment ready based courses. Best practices for making app's well tested and properly staged for active use and deploy. It's a topic that is missed very often.

[@WebDevSimplified]

I agree. I want to try to cover more testing related information on this channel since I find it quite enjoyable.

[@nerdiloo9863]

AI : You're welcome. Human.

[@BjornBrasse]

Please add more video's on testing. Perhaps a course specifically on this subject. I'm sure many people are interested!!

[@Misfittykitty]

@@BjornBrasse I agree--I would 100% sign up for a full course on this by Kyle. I loved his React course, and recommend it!

[@highestaccomplisher]

OMG. I am a Manual Testing upping my technical skills to become an Automated Tester and it is the first video I see (after months of seriously researching a lower than beginner level tutorial) that really help me write my first Javascript testing script in 5min. Thank you so much.

[@calebsirma3867]

Never found a guy so smooth in explanation in 14 minutes.

[@bama2619]

The video was in the search and I chose your video. I see your 4 years old video and think that you were tired at that time. In latest videos you are more energetic.). Great videos, Kyle. Thank you.

[@michaelhuskey2608]

Definitely would be interested in more testing videos. A topic I only really became aware of when I started looking at job postings and my home made projects started getting more complex. Appreciate what you do!

[@AnishSana]

This was such a clear and concise explanation; thank you!

[@utkarshsingh.12]

Within 14 minutes, this guy made you learn testing even if you know nothing about it. Thanks!!!

[@tech3425]

It would be nice to have a Jest course for typescript and Express/React. Really helps us understand how to setup testing for our project

[@DRocksRecords]

Dude! Test seemed like a mile away before I watch this... I get just enough of it to start trying on my own very nice... thanks

[@FirstLast-gk6lg]

Came here for a refresher, last time i wrote tests was in school and i really enjoyed them then so excited to refresh my knowledge

[@PGBlanks]

I was broken after they introduced this to me at bootcamp, but you helped explain it very clearly! Thank you.

[@aktp4796]

At least they introduced it to you.. I’m a recent bootcamp grad currently job searching and getting back to these necessary fundamentals after realizing how ill prepared I am.

[@daurham]

Bro SAME

[@daurham]

Looking at the mess and I’m thinking “sooo theyre functions..? But how.. & wtf is toBe” 😂

[@joshr.2600]

I've watched plural sight for 1 hour. And YOU have explained this 10x better in 13 mins. U have my like n sub. If u have a paid channel. I'm ready

[@jthomasaurus]

I am very interested in more testing videos. This was a great intro for me, and I’m at that point in my self-teaching to start getting into testing my code! Look forward to more.

[@WebDevSimplified]

Thank you! I would definitely recommend getting stated practicing testing since I found it was a skill that took a ton of practice for me to get good at.

[@hugoperez1318]

This was very well explained and demonstrated, great job Kyle! I think a lot of us would like at least another video going deeper into testing, explaining better practices, and whatnot. Great video, though.

[@cengiz-ilhan]

he is teaching everything simple. AWESOME

[@avidadedanton]

Thanks! really nice video! *adds Test Driven Development to resume*

[@martinag6607]

Thanks man!! Super easier to have the --coverage, super helpfull, and well explained!! Much appreciated!

[@marsdwarf]

Fantastic tutorial, I love that it's short. Thanks!

Amazing tutorial! I was afraid of start studying this topic because it seemed so hard. Now, this video gives me a more clear idea. Thanks!

[@daviddada7771]

You're really simplifying web development Thanks so much for this video

[@DavidLeDuc1]

This is a really great intro to testing using Jest. It would good to see more testing videos, possibly ones that cover plain vanilla (no framework) javascript and testing functions that manipulate DOM.

[@RogerThat902]

Yes, would like more testing-related videos. That was great. I think my biggest issue is knowing what exactly to prioritize when testing because as you said, you can test almost everything, even though you probably never will.

[@WebDevSimplified]

I would say you should prioritize the core business logic of your code. Essentially whatever code is the most essential to your project should be tested first.

[@nagasaran3856]

Good clarity is maintained throughout the video

[@Jonathan_Henderson]

Great content as always Kyle!

[@NiceChange]

i know this was posted a while ago.. but wow. creating test made so easy..Huge thanks!!!!

[@masihkarimi5952]

Wow, that was amazing, I've got the complete concept of how the test case should look and work, Thanks for the great content Man !!

[@AlexGrigoreDEV]

Very helpful, even though there's a lot more to know about JEST, it's a well rounded primer. Thank you!

[@deepumon.d3148]

Bro Thanks for this amazing video. Actually, I have to write JEST code in our organization. Your video helps me a lot. Please do more videos about JEST.

[@kakitayuri]

Really really good stuff dude! Coming from nearly a decade of professional Android development, moving to web work, I was hoping to find a succinct explanation about quick setup and coverage. Definitely a thumbs up and a sub from me. I know you're focusing on newer devs a lot, but even at the senior level needing a quick intro, very helpful stuff!

[@vibonacci]

I'd definitely would like a video that writes a full test suite on a small but real-life project that shows how to write proper unit tests beyond the common a + b examples.

[@WebDevSimplified]

I really want to do this, but I need to find the right project first. Most of my KZbin videos are not large enough to make a full video out of testing them.

[@vibonacci]

@@WebDevSimplified Ok. But maybe just a project where you test some very common use cases like logging in / auth, CRUD operations on a 'User' or 'Company'. Simple stuff that is very often done.

[@aimablebancunguye9617]

Wow! you are super great, i was struggling searching for jest course. thank you for your video.

[@nataliadziedzic9278]

Thanks for this video. If you are thinking about continuing this series then I think tutorial on testing in React would be a great help for newbies ;)

[@AlexTechie]

Great video! I've known about testing for a while, but I (personally) can't think of a place I'd use it. I know that's a me-issue; not knocking testing. Hopefully, in your next video on testing, you do can walk us through some real world use cases. Keep up the good work! 👍

[@WebDevSimplified]

Testing us useful anywhere you have logic in your code. Literally anything in your code can be tested and you should definitley test the critical parts of your code

Hey Kyle! I know it's a bit late to post a question/comment for this video(considering the date of publish for the video) nevertheless, I have been watching your tuts and coding videos and I genuinely enjoy watching your videos and learn a ton of new things and concepts. I particularly love the specific topics like regex, testing, solid principles etc that you cover, which frankly I didn't came across on most other coding pros' channels. I love these indepth programming topics by the way and hence, it automatically draws me to your channel every now and then. Main question I had was, "what could be the main difference between a normal software(app) testing and the full on Pentesting?".. Generally, I am aware of the definitions and the underlying principles but, I am quite assured that, your answer would defnitely shed some more light on the topics and help me go further in these topics. Thanks for everything, and love you!
