  • 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.
