It's a masterpiece! This was the first time I've experienced a course where the message of every single lecture was so neatly organized that I could learn without any roadblocks. In the beginning, it seemed to be heading towards writing readable code. However, as I progressed, it became increasingly clear that readable code is more about maintainability than just legibility. I've had many concerns in my professional work about how to create better designs and write better code, and I feel like this course really helped me find the right direction! In particular, I loved the part about resolving polymorphism issues using overrides within enums during work.

I always intended to use TDD for my projects, but I often ended up skipping it because I was pressed for time. This course was very helpful as it taught me the right mindset for testing and how to write better test code. Thank you!

I think I've gotten a general feel for testing.

I chose this course because I had no knowledge about testing. Not only can you learn about testing, but you can also gain practical tips for each layer, and it's especially great that you can learn about Spring Rest Docs. But why is this course so fun..? lol As I moved through each chapter, I found myself wondering what innovative thing would come next, and it was so much fun watching and practicing on my own. Thank you for providing such a great course.
