Delightful JavaScript Testing


Some features of this testing framework are:
 * Easy Setup: Jest is a complete and easy to set up JavaScript testing
 solution. In fact, Jest works out of the box for any React project.
 * Instant Feedback: Failed tests run first. Fast interactive mode can switch
 between running all tests or only test files related to changed files.
 * Snapshot Testing: Jest can capture snapshots of React trees or other
 serializable values to simplify UI testing.

Node.js is an event-based server-side JavaScript engine.
