I highly recommend this as an introductory course on testing! It's structured as a story that starts with why testing is necessary and demonstrates it through examples, making it easy to understand.

It was so much fun. I think we'll need a bit more team discussion before applying test code directly to the service project, so I'm planning to quickly add it to the design system repository first. Thank you for the interesting lecture~!

As you mentioned, it seems like my perspective on designing components is broadening.

It's so fun!

I understand it well.

This is a good course to grasp TDD. It's great to understand unit and integration tests, and also learn how to write them in actual code. The best part was the teaching: "Avoid testing detailed implementations; validate interfaces." I believe this content is somewhat akin to "code that is easy to modify."

The dependency versions of the provided materials are all at a deprecated level. When using the materials with outdated versions provided, convenience functions are difficult to use. Even if fixed, when using vitest in other projects, the vitest version must be changed every time the project is modified. It feels more like reading text with features written down rather than explanations. The time spent understanding by looking at official documentation or understanding by looking at the original module's core-level comments was overwhelmingly longer than the time spent understanding by watching the lecture, which raises questions about why one should watch the lecture. However, the advantage is that it does provide direction. If the majority of Inflearn lectures are like this, I think it's a problem with Inflearn as a whole.

This is a good lecture on testing.

Thank you for explaining about testing so calmly. It would be nice to have Vue.js use cases, but I think I can infer it and do it. 😊😊

Thank you for the good lecture!
