Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. Chai has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel. Plugins extend Chai's assertions to new contexts such as vendor integration & object construction. Developers can build their own plugins to share with community or use the plugin pattern to DRY up existing tests. You can also use it within the browser; install via npm and use the chai.js file found within the download. Browse our growing directory of custom plugins & vendor integrations to find the best tool for your needs. Chai has an extensive utility belt for plugin developers. Learn how to build your plugins & share.
