About the Course

Testing React Apps with React Testing Library is your complete guide to mastering testing for React applications. In this course, you’ll learn how to write maintainable, reliable tests that ensure your apps work as expected in the real world. We’ll cover the fundamentals of testing with React Testing Library and dive into advanced techniques to make your testing more efficient and effective.

You’ll explore how to mock API responses using Mock Service Worker (MSW), simulate user events in a test environment, and implement testing for complex scenarios like authentication, state management, and routing. We’ll also focus on refactoring techniques that improve the readability and maintainability of your code. With real-world examples and exercises, this course will give you the confidence to test React apps like a pro. Plus, you’ll learn how to maintain code quality using ESLint and prevent common issues before they become problems.

                Prerequisites

                To fully benefit from this course, a solid foundation in React is essential. You should be well-versed in all the core concepts, including components, hooks, state management, routing, and more. Additionally, a basic understanding of unit testing plain JavaScript code (without UI frameworks) using tools like Jest or Vitest is necessary.

                Here are the courses we recommend if you need to strengthen the fundamentals.

                I started learning programming w/ Mosh 4 years ago with his C# & .NET courses. Thanks to those I landed my first job. Then, I continued to learn from his materials and made the jump from Jr. to Ssr. and then to Sr. Software Engineer (my salary went 10x from my first job). Now, 4 years later I continue to learn with his excellent courses.

                Mosh doesn't fail to leave out important details. You can tell that Mosh has put a lot of thought into creating these courses. His professional and personal experience drives these courses to be thoughtful and outstanding.

                The best courses I’ve participated so far. Mosh has a unique teaching ability. His lectures are fun and engaging. The visuals are great. Relatively dificult concepts are explained with simple words. Whenever any one asks for a programming course I recommend Mosh Hamedani, and only him. Other courses I’ve had were at best mediocre.

                I love how every part of the course is broken down very well that even beginners can understand it and not feel overwhelmed, confused or carried away. Also how the lessons/course is in sections, one can go back to a particular section for review if need be especially when working on the exercises.

                I found this course to be complete and very clear and easy to follow. Mosh is very good at explaining, it feels like a friend talking to you very naturally, and the course is very entertaining. And it comes at an amazing value! I definitely recommend it!

                This is my second course from Mosh and it is great as well, The way he explains little details (how and why's) is very helpful and builds a solid base of understanding the code. Great instructor!
