Just did a random search and came across this video. Very good, Sam!Keep up the good work!

[@ovienaduken7296]

this is a very straight forward way to explain testing with supertest. Thanks

[@JJP-lb3ek]

Exactly what i needed in my life right now. Thanks!

[@jesuscama5354]

Thanks for keeping it simple and clean. 🚀

[@wralith]

It was just what I was looking for. Thank you very much for the clear explanation.

[@shahilhussain6466]

That was very quick and simple explanation and use case of Jest and SuperTest, thanks man!.

[@suhasvenkatesh7895]

Awesome, simple to understand. Simplicity in explanation. Thanks

[@BlackDragon-rj4sc]

I just started to create my first nodejs boilerplate with jest test and this video was very helpful to setup things

[@utsavojha2953]

Great video, great explanation !! Thanks 🤩

[@djvanschaik]

If you get a request not defined error, make sure to try: `const request = require('supertest')` instead of `const supertest = require('supertest')`. Other than that this is great!

[@sheheerali7059]

i should have looked at this comment earlier😅

[@nested9301]

"type":"module"

[@user-rq6ti7cy2q]

after done this I get ReferenceError: require is not defined ca you help me with this?

[@Shailendrakumar-ge5cf]

Thank you so much for the text version ♥

Thanks, bro. It helped me. Keep up the good work.

[@babykosh5415]

Great content mate! I'm on my first month as a backend dev with Node/Express and I'm looking forward to getting to know testing tools. Thanks for your explanation!

[@kostiantynkarzhanov9216]

Very good tutorial! Thank you! 💛

[@giachan4528]

I like these testing tutorials with examples. Thanks

[@SamMeechWard]

You are welcome 🤗

[@karinaillesova5706]

Hi, this was great video to watch while creating my first tests for my API endpoints. It does however make changes to my actual database. Would you make a video on mongodb-memory-server please?

[@debashisroyroy652]

helpFull .. Thank You. Expecting more nice things from you.

[@scrice9081]

thanks man this is awesome!!!

[@alex-dk2rj]

Glad you enjoyed it!

[@guillaume5623]

Great content, thank you

[@he01682936]

Nice video, thanks :)

[@ayushpratap4726]

waiting for the next part ! Try using Nest.JS with JEST Supertest.

[@tech3425]

Thanks a lot for this! Would appreciate it if you could make a video regarding setup for this kind of test suite with Typescript-Express

[@brentryczak]

Instant like after that first tip about the ports. That was my issue

[@ngneerin]

Have been trying to fix supertest with async app. Got fixed after watching this video

[@jbkwon]

You are so awesome!

[@attilaszombathelyi3]

great job

[@tom_c]

Sam, great video! Thank you for contributing to the community... I am having a problem trying to reproduce the core of what you explained. For some reason the test fails saying that the request received a 404 but it should be a 403 (returned correctly testing it via postman). I think it has something to do with the routes and passing the app object to the request function of supertest... Any comments would be appreciated. Thank you in advance!

[@nwigweuzochukwu6089]

In a user registration flow that involves sending verification emails, i'm getting this type of error: thrown: "Exceeded timeout of 5000 ms for a test. I guess it's because of the email sender request and response but how do i fix this?

[@antimaaaato]

Nice video!
Could you tell me your Node.js and jest, supertest versions?

[@danielsouza1824]

Thank you very much, the NODE_OPTIONS=--experimental-vm-modules npx jest solved my problem 😓

[@harmanmax]

Thanks mate , in windows i am using cross-env package and in package.json "test": "cross-env NODE_OPTIONS=--experimental-vm-modules jest --watchAll"

[@zainhaider1633]

hey great video but i wan to know how not to affect you actual DB during test?

[@sammygopeh7578]

Lord! I cannot say thank you and enough

[@SamMeechWard]

consider becoming a channel member ;)

[@MattBodman]

Love the vids! What's the music in this one?

[@danielsouza1824]

How to overcome "Jest did not exit one second after the test run has completed."? Now I'm facing this problem. Did you solve that?

[@Mercio2]

thanks

[@TheSerikzhan]

nice

[@saulramirez727]

Supervideo of superset

[@Codethier]

i owe you a beer mate

[@12kenbutsuri]

Thank you for the tutorial. I'm a bit confused with one thing though, when was supertest ever used? wasn't everything here contained in jest?

[@krsnyder128]

At 4:36 he mentions that the request function comes from supertest!

[@12kenbutsuri]

@@krsnyder128 thank you! I missed that part.

[@trant4]

@@krsnyder128 Does not work for me, request is underfined

[@RajendraPrasadyk]

Can we get video on with middleware supertest

[@daniel.w8112]

where do we use jest here ?

[@FredWang]

To use `import express from 'express'`, are you using the latest node version or by importing ESM ?

[@user-lb8to5yr6r]

He wrote "type": "module" at the package.json file. It tells node.js to use ECMAScript modules instead of a default CommonJS

[@cannabisanomaly]

Anyone been able to figure out how to use EJS syntax for importing/exporting on the backend instead of CJS? I still haven't been able to figure out how to configure that 😅

[@22SPORTSLIVE_10]

Can someone help with some unit test plz

[@eddyeffy]

Something is wrong with your dependecies

[@TenthFir]

Why do you guys add music to a course video... I am here to learn. And even the music volume is more than your speech

[@SamMeechWard]

No guys, just me. I like the music 🤗

[@arcan762]

bruh turn the music down it is so annoying the way it jumps all over the place

[@ms.Mysh1]

I can’t concentrate because of your beautiful face 😅

[@sohrabradmehrgaming1556]

You should become a teacher or something

[@SamMeechWard]

I don't think i'd be able to put up with the students

[@matthewbeardsley7004]

Having this as my script saved me hours!! Thanks!!
"test": "NODE_OPTIONS=--experimental-vm-modules jest"

[@alidemircix]

Why does not work only writing npm test for this. I spent about 2 hours to solve this problem but I don't know why do we use "test": "NODE_OPTIONS=--experimental-vm-modules jest" code

[@djaos-8326]

thanks

[@SamMeechWard]

You're welcome!
