##Add-ons

Assertion Libraries

• should.js - BDD style shown throughout these docs
• chai - expect(), assert() and should style assertions
• expect.js - expect() style assertions
• expectations - Jasmine-style expect()
• unit.js - simple, fluent assertions
• unexpected - extensible BDD assertion toolkit
• inspect.js - modern BDD style assertion library

Mocks, Stubs, & Spies

• sinon.js - Test spies, stubs and mocks for JavaScript.
• simple-mock - Super simple mocks, stubs, and spies with 1-step sandbox restore.
• nock - HTTP mocking and expectations library.

Plugins

• mocha-plugin-co - plugin to enable generators support for (using co)

Interfaces & Reporters

• mocha-suit - OOP like mocha wrapper
• mocha-clean - Cleaner stack traces
• mocha-matrix - concise matrix reporter for the browser
• mocha-cakes - BDD acceptance tests, Cucumber Given/When/Then stories add-on for Mocha.
• mocha.parallel - Run async mocha specs in parallel.
• lcov-reporter -- lcov reporter
• text-cov -- Text summary in console of code coverage
• JSCovReporter In browser Javascript coverage reporter using CoverJS instrumented code.
• qunit-mocha-ui - A Mocha interface that more closely replicates the QUnit API, including QUnit's assertions.
• mocha-qunit-ui - Mocha interface that is API-compatible with QUnit
• mocha-ui-tsexports - Mocha interface that enables tests written using TypeScript classes
• xunit-file - A Mocha reporter similar to xunit, but writes to a file (excludes all console.log output that breaks the xml).
• WebConsole-reporter - A Mocha reporter that displays reports in browser console. Works faster than html reporter and provides clickable stack traces.
• mocha-slow-reporter - Outputs a profile-like tree of the tests/hooks to help you fix test-suite slowness.
• mocha-unfunk-reporter - An alternate to the default Spec-style reporter for improved usability and added compatibility features for use in various low-tech scenarios. Does not use console cursor tricks or positional ANSI codes.
• mocha-fivemat-reporter - Reporter format inspired by fivemat. Better signal vs noise ratio for larger test suites.
• mocha-teamcity-reporter - Teamcity reporter for Mocha.
• loca - Reporter in your browser's console.
• mocha-retry - Allows you to retry a test if it fails using the bdd ui. Useful on unstable tests, like those that drive a browser.
• child-reporter - Reporter, that create a child process with stdout to console. Useful for testing modules that redirect stdout to /dev/null or logs
• report-viewer - Cli for piping a unit test result directly into your browser. Combines the debug level of the console with the pretty output of a browser ui.
• mocha-typescript - TypeScript OOP, decorators based, mocha test interface.
• mochawesome - Produces a gorgeous standalone HTML/CSS report.
