How can I use jest on React using npm?

Question

My application is made using create react app and npm. In the jest's official documentation, https://jestjs.io/docs/tutorial-react , they only have information about testing CRA apps using yarn. Does this mean we cannot use jest to test our React app using npm?

Answer 1

You can use jest with CRA, in fact it's already built-in to CRA.

Try run npm test
