Do you write automated JavaScript tests?

over 7 years ago from , Developer

I write a lot of Ruby and tests are a part of the process. This is not so while writing JavaScript. I've always found this odd since JavaScript is usually user facing - you would think it would be rigorously tested!

Realising this, I finally learned how to start testing JS within React.

What are your thoughts on testing JavaScript? Is it important? How do you write tests? What's your tooling look like?
