Practical Testing: Practical Testing Guide

Hello, instructor! I am a new backend developer in my 4th month. I listened to it because I had to use RestDocs at work. As a result, I felt the need for testing, and I was able to learn how to write test code. However, the part that I am most satisfied with is that you taught me how to use it in the field. Of course, I was also very grateful that you answered my questions accordingly. I was especially grateful that you taught me how to distinguish DB endpoints through @Transactional(readOnly = true), and how to distinguish RequestDto and ResponseDto between Service and Controller, and in response to my question, you explained that the performance of the application is more important than the readability of the code, and that there are parts where the readability of the code decreases, so I refactored my actual code! Oh, and I'm using it well because you also told me about guava. ㅎㅎ I really came to learn RestDocs, but it was a lecture where I gained a lot more as a bonus. Thank you so much for the lecture again. In addition, I think it would be good if you could share your field experience, and make a project lecture for the field. Many of Inflearn's lectures are focused on students or job seekers, and of course, there would be more demand for those parts, but I don't think there are any project-based lectures that really target the field and have high-density concerns. If there were an advanced lecture that goes beyond simple learning, and if the instructor filmed it, it would be really, really great. This is my personal wish, so thank you for reading^^ Even if it's not a project lecture, I will definitely take the instructor's other lectures. I personally think that developers are people who constantly think, and in that respect, I felt that the instructor's thoughts were in line with mine (as an answer to my question), and it was an honor. When I start writing test code again in earnest I will review the lecture and ask questions again. Thank you.

Hello, I am a developer with 6 years of experience. I only know the general idea of test code and actually haven't used it much in practice. My conclusion is that there are many experienced developers who can't write test code elegantly. In fact, I thought it was "annoying" before watching this lecture. I am one of those developers. However, I changed my mind after watching this lecture. I am a senior developer and a developer who was afraid of test code, so I learned a lot from this opportunity. In addition, JPA is taught in a way that is close to practice, and if you don't have the basics, you may wonder "Why?", but this is exactly the lecture I wanted. Thank you.

First of all, I would like to thank you. During the 12 hours of lectures, I was able to have a productive time thinking about the intention and purpose of writing tests. In addition, I was able to get a grasp on the vague concepts of tests, and I was able to be motivated to develop an uncompromising development spirit. In the future, I will not rest on my laurels, but will apply the test code knowledge I have learned here and there, and grow into a developer who can write tests regardless of the tools!

I have been writing tests without any knowledge until now.. This lecture helped me build the basics to create more robust code. I recommend this lecture.

This lecture really scratched my itch when it came to testing. I was studying alone and had no place to get feedback on test codes, so I was looking through several project repos from IT clubs or educational programs and thinking about how to write test codes. This lecture really helped me. Now that I know the direction and method to some extent, I just need to learn it myself and make it my own. Thank you for the great lecture. I could feel that you put a lot of effort into preparing the lectures. Thank you.

There aren't many unit test lectures related to Spring. Through this lecture, you can learn how to test each layer. Also, you can clearly solve your concerns with the instructor's good Q&A. Thank you for the great lecture.

I needed to study for the test, so I was struggling by looking up books and references on my own, but thanks to you, I was able to study really well. I'm really grateful. I'll study hard~!!

This is truly a lecture with so much to learn. You can learn a lot, from the importance of test code to how to write test code well, and much more. I was able to clearly understand and move past the parts that books or other lectures tend to quickly skip over because they're not the main content. And I was so grateful for the instructor's effort to share even one more piece of knowledge throughout the lecture, aside from the main topic of testing. (ex. CQRS concepts, ...) The lecture quality is excellent, and even though it's been quite some time since the lecture was released, the Q&A seems to be handled well. I hope more lectures of good quality will be released in the future!
