React Testing Library and Jest: The Complete Guide (Udemy.com)

Muy buen curso, en mi caso tengo un nivel intermedio de ingles y pude entenderlo perfectamente, las explicaciones son pausadas, el curso tiene buena calidad y buen audio, bastantes ejercicios y explicaciones tanto en codigo como con diapositivas, si tenes 0 conocimiento es perfecto :)

The course is relatively short and can be completed in about 2.5 hours. However, I felt the content drifted away from the core topic of testing at times. In my opinion, Sections 2 and 9 are the only truly valuable parts. The 'rtl-book' section was quite distracting and didn’t hold my interest, making it difficult to stay engaged.

Each and every explanation is in very much detail and explained in very good way. The course is very good in understanding the rtl library and the flow how to exactly test. Thanks for this course

It was quite informative precisely and helpful, I was taking it during this holiday 2025 so there are no response to my question when I encountered problems but overall its a good course to start learning testing.

It was excellent. The way the teacher explained the hole course was very simple, easy to understand. I recommend this course. But I was hoping to learn more about mocks, how to mock classes, dependency functions, how to mock global states, how to deal with jest.mock and jest.spyOn and stuff like that.

This course is fantastic to get grips react testing. It is a beginner level course so the instructor really takes it slow (which is why for me it was a bit inconvenient since I am taking it as a refresher). I did like the debugger section at the end (albeit he skimmed really fast on the script to run without explaining what the options of the command are).

Right off the bat, I would like to say that I already had several years of experience with jest. I took this course, mainly to fill the gaps that I am missing. I am really pleased with this course, it helped me on my thought process.

I could not always follow, but replayed the parts, especially at the end, over and over again, until I saw what you did there. Nice job, your teaching style really connects with my learning style, because you repeat important stuff over and over again, which I very much liked and hopefully never forget ;)

This course is so short that I thought it’s gonna be simple. It turns out not to be the case. The lecturer starts off with the basics and carry on with increasingly high level techniques (e.g. techniques I don’t expect me to pick up or invent myself) of testing. The last few sections are arguably the most “eye-opening” ones, just like what the lecturer himself said. Definitely worth every single bit of your time here.

5 stars for the explanation, and 5 stars for the detailed debugging strategies and thought processes. Most courses say, here is the code, here is the piece of code for it, but Stephen really digs into the core. What I wanted to see: It would have been great if there was few sections regarding useMemo, useContext, useReducer , react hook forms etc, purely because there are mostly used in all projects. But efforts need to be appreciated! The course was worth for me
