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


$ npm install -g mocha
$ mkdir test
$ $EDITOR test/test.js # or open with your favorite editor


var assert = require
describe)


$ mocha
1 test complete



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