I was completely lost when it came to test code, but this course explains everything step by step in a way that's so easy to understand! I've been seeing test code quite often in job requirements and preferred qualifications. By watching the lectures and practicing along, you'll get comfortable with it, and once you actually use it in real projects, it'll boost your job competitiveness too.

It was great that it was easy to understand. It was helpful that you covered React Query and custom hooks together in the lecture examples, and I think I can apply them directly to actual projects. Overall, the explanations were easy to follow, so I was able to keep up until the end. Thank you for the great lecture!

I didn't realize the importance of test code. After experiencing it in actual work, there are more human errors than I thought... I also missed a lot of things... So I desperately felt the importance of test code, and this lecture was a great help as it allowed me to try it out easily and comfortably. It was so good that you got straight to the point and taught only the core essentials without beating around the bush!

I couldn't write a single line of test code before, but now I've gotten to work with MSW and even Playwright. Instead of just explaining theory, showing it with practical examples makes it so much easier to understand. I highly recommend this to junior developers like me!!
