chai: A JavaScript repository from zzen

Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.

For more information view the documentation.

Installation

Chai is available for both node.js and the browser using any test framework you like.

Node.js

Package is available through npm:

npm install chai

Recommend adding it to package.json devDependancies.

Browser

Include the chai browser build in your testing suite.

<script src="chai.js" type="text/javascript"></script>

Currently supports all modern browsers: IE 9+, Chrome 7+, FireFox 4+, Safari 5+. Want to know if your browser is compatible? Run the online test suite.

Plugins

The Chai community is growing! Plugins allow developers to expand Chai's available assertions. Here is what the community has come up with so far:

chai-spies is a basic spy implementation for chai. It's also a good resource for building chai plugins that work in both node.js and the browser.
chai-jquery by @jfirebaugh provides deep jQuery integration with chai's should and expect.
jack by @vesln is a mock/stub library that can be used as a stand-alone or with chai.
sinon-chai by @domenic extends chai with assertions for the Sinon.js mocking framework.
chai-as-promised by @domenic extends chai with assertions about promises.
