It is a great thing that the instructor takes time to answer the questions. Also, the course covers pretty much what I expect about this topic

Muy bien abarcados los temas principales y lleva bien la teoría con la practica.
By Yuliana Murillo Hurtado on 3/26/2023
Basic, short but good. It would have been better to go deeper into e2e and TDD testing.
By Fml on 2/28/2023
Not bad, pretty much good for beginners as it work through step-by-step guides.
By Daniel Sandoval on 2/20/2023
This is exactly what I was looking for. I just need to apply the code with Sinonjs but the course worked for me. A very complete and understandable course.
By Madhu N on 2/14/2023
Nice course to learn automation testing, explanation is good
By Daniel R on 1/16/2023
i didnt get that part with all the mocks in unit testing. would have wished for more detailed explanation.
By Davor Jovanovic on 12/30/2022
Overall, the course is good and gives a good overview of unit testing in NodeJS Express applications. I rate this course 4 stars because testing with Jest and TypeScript is not covered. I personally consider it lazy not to do it in TypeScript, because any scalable app will utilize TS, it is too easy to do it in plain JS compared to TS. On the other hand, the instructor is really devoted to help students and to reach out to anyone who has any issue regarding course, therefore, he gets 5 stars from me.
