While taking the class, I organized the content on the blog. (I didn't write all the content though....) It was a little difficult to follow along because I was using IntelliJ, but on the other hand, I also wanted to use IntelliJ someday. (I'm currently practicing with the community version.) If TDD is test-driven development, I think this class is TDC. Test-driven classㅎㅎ Because it taught me how to use tests. Before taking the class, I hesitated because of the price, but after taking the class, it was a class that made me realize that the price was low. Anyway, thank you for the great class. I will write a review for other classes as well.ㅎㅎ
