So helpful thank you. I hope there's a frontend testing tutorial too. I'll be doing that next if there is! Also reading the book 'Unit Testing: Principles, Practices, and Patterns'.
Everything is clear,so well done, but for my taste way to easy and basic, could have gone much more in-depth for most devs. Including class mocking, actual mocking use cases, snapshots, setup /teardown, scoping, coverage, many more things I would like to see, but maybe in Part 2!
Great video and lecture. I have been able to link my replit account with my github but I have been unable to link or upload the files of my repositories from replit to github. It's only showing my repositories on github but it's empty. How do I upload the files?
At 7:28. Line 7, dont we need to replace ( "echo \"Error: no test specified\" && exit 1") with ( "jest" ). Instead of "test" with "jest"?? Can someone please clarify. Thanks
Jump to 13:36. He clarifies here. I think he put this part in here to show that you have to update the value, or the right-hand side of the key: value pair.
The callback function is a placeholder for any function that will be passed as an argument when calling fetchData. This pattern is common in asynchronous programming, where you provide a function to be executed once an asynchronous operation (in this case, the timeout) is complete.
Definitely one of the best tutorials I've seen, very appropriate speed for beginners! Thanks
This is a great simple tutorial on jest. Very much enjoyed it and ready to do Jest tests and TDD.

much needed one. please add other testing libraries as well especially ones for react

Wow day ago thought it was years ago. Perfect timing for me I guess
so simple tutorial about jest . please release more parts about this topic
46:20
function fetchPromise(isComplete) {
return new Promise((resolve, reject) => {
if (isComplete) {
setTimeout(() => resolve('Hi'), 1000)
}
else {
setTimeout(() => reject(new Error('error')), 1000)
}
})
}
test("fetchPromise is 'Hi'", () => {
return expect(fetchPromise(true)).resolves.toBe("Hi")
})
test("fetchPromise throws", () => {
return expect(fetchPromise(false)).rejects.toThrow("error")
})
This man offer very good explanation. Good job!
Nice tutorial, but I wish there could have used a more complex example other than that sum function. Still a good video!
Great and amazing tutorial. Thank you
Naija to the world 🎉🎉
great! how about more in-depth and with React?
Woww!!! This is exactly what I wanted

I was actually looking for testing react applications... I think the last video you guys uploaded was about a year ago... would like a new updated one

Thank you LeBron James
What theme does he use?
Got lost around 39:00, why there's a "callback" function inside fetchData? Why the test calls a function (fetchData) of a function (callback)?
The callback function is a placeholder for any function that will be passed as an argument when calling fetchData. This pattern is common in asynchronous programming, where you provide a function to be executed once an asynchronous operation (in this case, the timeout) is complete.
tf i was about to search jest and this video pops up loool
Does anyone know why intellisense does not work?
Can we not add two import in same file say i want to import sum and myFunction both, on executing this i am getting an error saying module not found ?
what dark theme is this?
Beautiful 😊
What the theme is used in your VSCode?
Ya found the answer, mate?
@@_tot_ no
ayu theme
Is this applicable to typescript?
Pls is it?

I like how online courses are starting to cover indian guys giving the lecture by presenting the white guy first
He does not look nor sound Indian.

Can we move away from JS already? It’s getting toxic these days.
Not much help because instructor himself is not confident could have been better specially the async part.
And how did you come to that conclusion 🤷♂️🤷♂️🤷♂️
ferst
thank you
