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!
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.
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?
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.
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!
Naija to the world 🎉🎉
great! how about more in-depth and with React?
Nice tutorial, but I wish there could have used a more complex example other than that sum function. Still a good video!
Thank you LeBron James
What theme does he use?
Woww!!! This is exactly what I wanted

what dark theme is this?
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?
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
First' view on this course ❤❤
Land
Does anyone know why intellisense does not work?
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.
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 ?
Use named import
Beautiful 😊
Is this applicable to typescript?
Pls is it?
tf i was about to search jest and this video pops up loool
What the theme is used in your VSCode?
Wow Nigeria to the World
2:22 could have just ran "code ." from the terminal to open up VsCode :D
JIT video
Not much help because instructor himself is not confident could have been better specially the async part.
❤❤❤
🙏🙂👍
Can we move away from JS already? It’s getting toxic these days.
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.
