While studying Spring and looking at the codes on how to write tests, I noticed that there were many meaningless, repetitive tests. So I wondered why they were writing such repetitive tests. Then, I happened to see a new lecture on Infraon titled Why Spring Test Developers Fail to Write Tests. I thought it was just for me! So I boldly paid for it. After completing the course, I think I made a choice I don't regret. I paused the lecture for 10 minutes and thought carefully about what the instructor was talking about. So, although the lecture was 6 hours long, I felt that it had the quality of 60 hours. I am grateful to the instructor for broadening my perspective on software engineering.
