Anyone know some good tutorials for Jest?

I’m looking to learn Jest to write tests for a design system I am building for work.

I am responsible for building the components (button, alert, etc.), but also need to include Jest tests (they were as vague as that).

I have zero experience with test-driven development, and the Jest documentation is very complicated and technical.

The tests would need to be for UI components, so do I learn unit or snapshot testing?

Everywhere I look, it’s written as you should already know what to look for. But I’m in the case of “I don’t know what I don’t know”, so I don’t even know what to look for.

I feel very lost. Any direction would be very much appreciated :)
