Testing is complicated. I’ve certainly never been good at it. For the longest time, I’ve only been focused on basic function input-output unit tests. Why? Because they were easy — you didn’t need to render HTML, you didn’t need to query DOM elements, you didn’t need to interact with said DOM elements. But of course, React component testing is a necessity for any mature codebase. And it finally came time for me to sit down and figure it out.

That’s when I discovered React Testing Library. And suddenly, everything seemingly became much simpler. All the complexities that I’ve encountered, but not understood, that made me put off React component testing disappeared. Hopefully, the same will happen for you.
