Jest: Simple JavaScript Unit Testing

Jest is a JavaScript unit testing built under the Jasmine test framework. It is a tool that automatically finds tests to execute in your repo and mocks dependencies for you when running your tests. It also allows you to test asynchronous code synchronously, run your tests with a fake DOM implementation (via jsdom) so that your tests can run on the command line and run tests in parallel processes so that they finish sooner. It was created by Facebook.
