This repertory is a collection of simple demos of Jest for my blog post jest-tutorial.

First, clone the repo.

$ git clone https://github.com/hezhii/jest-demos.git

Then, install the dependencies.

$ cd jest-demos
$ npm i

Run all the tests.

$ npm test

You can also run a single test by npm test path/name.test.js. For example:

$ npm test async/fetch.test.js
