Mocha (JavaScript framework)

Mocha is a JavaScript test framework for Node.js programs, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library.

Assertion libraries
Mocha can be used with most JavaScript assertion libraries, including:


 * should.js
 * express.js
 * chai
 * better-assert
 * unexpected

Usage and examples
For asynchronous testing, invoke the callback, and Mocha will wait for completion.
