A great course, probably the best testing course I've ever taken.
After watching other courses on the same topic, this is the first one that I'm actually excited to dig into.
This course exceeded all my expectations. It has the right amount between practice and theory. The teacher is amazing and thoughtful and she answers the students.
I have taken several courses on Udemy, and this is the best one where the teacher doesnt just lecture, but actually structures the class so that I learn the material.
Who this course is for
Next . js developers who want to learn how to test all aspects of their app
