    React Testing: Setting up dependencies

    To write tests for our React code, we need to first install some libraries for running tests and writing assertions. In this lesson we walk through setting up Mocha as our test runner and expect as our assertion library. We will also set up some React and JSX specific test tools (React Test Utils) to make writing our tests easier.

    NOTE: There are many alternatives to Mocha, expect, and the other test tools we use in this course. Although we use these specific tools and libraries, the testing principles apply to all other tools.
