React Testing Mastery: From Basics to Advanced Techniques is your comprehensive guide to mastering automated testing in React. This course is packed with coding techniques I’ve learned over 20 years as a software engineer, along with numerous real-world exercises to help you become proficient at testing React apps.
Automated testing is essential for building reliable, maintainable applications that consistently deliver value. You’ll learn how to write robust, maintainable tests with React Testing Library and simulate user events in a test environment. We’ll also dive into advanced techniques like mocking API responses with Mock Service Worker (MSW), working with @mswjs/data and @faker-js, and handling authentication, state management, and routing in tests.
You’ll master refactoring techniques to make your tests and code more readable and maintainable, and we’ll cover tools like ESLint to catch code quality issues early. By the end of the course, you’ll have the confidence to test your React applications like a pro and ensure they run smoothly in production.
This course is clear, concise, comprehensive, well-organized, and practical—everything you need to become a React testing expert.

Success Stories
Don’t just take my word for it—hear from students who have transformed their skills and careers with this course.
Been recommending Mosh for years... probably a decade by now. I've lost count of how many developers and business people I have shared one of his videos with. Not much to say other than he's one of the best instructors out there. Great personality for teaching and a solid mastery of the subject matter. He's always going to be my first stop for learning something new.
Mosh helped me land a job as as a Mobile software engineer
I'm a self taught software engineer. During this period of study I completed many courses, trying to emulate a computer science education. Mosh's courses helped me all the way and the ones I continue coming back to and referencing as a professional software engineer.
I already held a degree and didn't want to incure the cost of going to college again. I'm also pretty motivated, so Mosh's structured courses worked well for me.
May courses will teach you a framework or technology, but these are highly perishable skills. Mosh will teach you to think like a software engineer and load you with the correct fundamentals that will give you confidence when you get in the workplace.
Thanks for everything Mosh!
The best investment I have ever made
Mosh is an outstanding teacher. His lessons are easy to learn and can be followed at your own pace, making them incredibly convenient. I've been learning from him for over four years, and the growth in my professional career has been remarkable. It's totally worth it. I am incredibly thankful to have found him.
Mosh comes up with the best, well-structured and informative courses as always. I have seen most of his YouTube videos in his channel and he is the main reason I fell in love with programming. Mosh not only teaches you the concepts, but also points out what it takes to be a professional developer that makes one stand out. I highly recommend his courses to all.
Thank you so much, Mosh
Mosh never ceases to amaze me. His courses are always top-notch. Mosh manages to teach complex things easily. Thanks to his React course, I became a programmer and got my first job. If you want to learn from the best, you should choose Mosh as your mentor.
