JavaScript Unit Testing - The Practical Guide (Udemy.com)

Max explains things very clearly and very concisely, its easy to follow and easy to digest the material in a granular way, which helps a lot when theres not a lot of spare time to learn new things. PS: I got 4 or 5 of his courses already. (would love a Python course from him by the way)

It's a practical course that touches the very foundations of unit testing, with concise explanations and exercises. It also touches mocking and spying and how to do them using Vitest. Now I feel less confused about the two. Overall this course is quite well-organized and friendly to testing newbies with actionable demos.

This is my second course by Maximilian Schwarzmüller, and once again, it’s excellent! The explanations are clear and well-structured, with a great balance between emphasizing the important concepts and skipping over the less relevant details. Max’s clear English and perfect intonation make learning much easier and more enjoyable. I’ll definitely come back for more of his courses!

Es un buen curso si no sabes ni siquiera que son las pruebas unitarias. Lo que no me gustó es que va muy rapido, eso no es problema en la mayoria de las secciones pero particularmente en la seccion 7 y 8 que en mi opinion son las más complejas, deberia bajar la velocidad y profundizar más en la explicación ya que es muy facil perderse y en mi opinion hizo falta mayor detalle en la explicación de estas 2 secciones.

This course has been very helpful to me. When I saw a test code with Jest for the first time in a React course, it seemed very bewildering to me, but this course opened my mind to the amazing world of code testing. Thanks to the course's content and the instructor's didactic, I could understood how a testing flux works and how to write one. It will help me a lot in my career.

Good course to cover the basics. Hammers home the "need to practice" mantra. I think an awesome addition would be a further section where a non-trivial application was taken and the entire testing process was added, perhaps one of the apps from another academind course that goes beyone the basics, although this would add some hours to the course it would set it apart and above other jest/vitest offerings.

This was an excellent introduction to testing. I highly recommend it. Max is an excellent teacher and in this course he really focus on making sure you understand what testing is but, most importantly IMHO, what mocks are and how to create and use them. To me this was always a pain, I couldn't figure out how to use them effectively and how they really helped you get rid of side effects. Thanks to this and the further study I am doing on stubs, fakes, etc, I am getting the hang of it! Great course!

Já fiz vários cursos do Max e é sempre uma experiência boa porque ele tem uma ótima didática e as aulas são interessantes. Até pessoas com dificuldade com atenção conseguem ver as aulas até o final e compreender tudo. Mas atenção: o curso é todo em inglês. As legendas (também em inglês) e a boa pronúncia do Max ajudam, mas é preciso saber inglês.

Great course indeed ! Max starts from the very basics of JavaScript testing and covers everything from the setup to the philosophy of testing. Explanations are also very clear and concise and it's overall a very good course to get introduced to unit and integration testing in JavaScript.

Well-structured course with improved presentation style & slideshow. Hopefully, such improvement can be implemented in subsequent new/rework courses. Max did mention some extra points to avoid students' confusion, which happens a lot in the old course. Great improvement & keep it up!
