I am getting this error when I import the expect function from chai and run it "Error [ERR_REQUIRE_ESM]: require() of ES Module /home/dan/Documents/mocha/node_modules/chai/chai.js from /home/dan/Documents/mocha/test/indexTest.js not supported. Instead change the require of chai.js in /home/dan/Documents/mocha/test/indexTest.js to a dynamic import() which is available in all CommonJS modules. at Object. (/home/dan/Documents/mocha/test/indexTest.js:2:18)". How can I fix it? Thank you
In order to fix this, you've got to do two things. Firstly, replace the lines const assert = require('assert'); and const { expect } = require('chai'); with just one which is import { assert, expect } from 'chai'; Next open up your package.json file and pop the following line just above your "scripts" property: "type": "module"
I think 'New York City' is much cooler 😀Sinon is for stubbing which we go through in this video (th-cam.com/video/gD4Sg3OuMiA/w-d-xo.html) Enzyme is for React projects.
Whenever I am trying to run my test using npm run test, it is giving me ES module scope error. I am stuck with it since yesterday but still can't find solution. I have tried everything : from including type: module in package. Json to naming files with .mjs extension and what not. Please tell what should I do to run my test without any module error
How can you have the terminal lines: "at Context..." "at process.." in light grey font color? They show in aggressive red on my default VScode window and it is so much worse. Thank you very much!
I have a question. When we use chai, do people usually do [ expect().to.be() ] instead of [ assert.equal(,) ] ?? I just want to know which is the more common style. Thanks, I’m really grateful for a great tutorial for javascript testing.
how can we write test cases for function that does not return any thing? I mean in this video you have used add and sub, so they return either a+b or a-b. What if i dont return a+b and rather store it in a variable. How do you prepare test for that?
Depends on what the function does - is it calling other functions (you can check that they get called by spying / stubbing them) or does it create a side-effect elsewhere (you can check that the update has gone through).
Make sure you got Node installed. then run "npm init -y". Then you can run "npm install --save-dev mocha". Then create a folder in the root of your project (same level as package.json) called "test." Then go into package.json and change the value of the "test" property to "mocha test". Then run "npm run test" into your command line. You should see a failing test. Then just follow the video from there.

Awesome you did my day! Your video helped me with "function is not a function" error. Thank you very much!
This is insanely clear and concise. You make life easy!
Cheers! Hope you found it useful!
Awesome ! Thank you. This video and the next one are exactly what I was looking for
Great! Hopefully you'll be up and running with unit testing now!
Thank you! I`ve been soo lost with other exponaitions,but yours is top!
Thank you very much!
Awesome tutorials man, subscribed! Keep up the great work.
Thanks very much Thomas! Hope you found it useful.
a tip: you can watch movies at flixzone. Been using it for watching all kinds of movies recently.
@Trace Tate yea, I have been using Flixzone for since december myself :)
Great video. I was exactly looking for this
Great! Hope you found it useful?
Amazing tutorial!
Thanks very much!!
Thank you so much! You explained it like a pro!
Legend!
Thanks very much!

very good video
Thanks for your support!
Nice intro! And SMH, I've been calling 'nyc' (nice) as 'New York City').
Where do enzyme and sinon come into play?
I think 'New York City' is much cooler 😀Sinon is for stubbing which we go through in this video (th-cam.com/video/gD4Sg3OuMiA/w-d-xo.html) Enzyme is for React projects.
Would've been nice if the video wasn't only on 360p! hehe

I have a question. When we use chai, do people
usually do [ expect().to.be() ]
instead of [ assert.equal(,) ] ??
I just want to know which is the more common style.
Thanks,
I’m really grateful for a great tutorial for javascript testing.
that's the basic case, i suppose expect has more methods to compare than assert.
how can we write test cases for function that does not return any thing? I mean in this video you have used add and sub, so they return either a+b or a-b. What if i dont return a+b and rather store it in a variable. How do you prepare test for that?

谢谢分享.thanks.
You're welcome 😀
Is the stripe tutorial not ready yet ?
It's on my todo list, been busy at work recently so apologies about the delay😢
@@codewithbubb I have completed that leave it now
how can we type-check the code?
When I write npm run test it gives an error saying mocha is not defined as internal or external command.HElp??
