Chai

Chai is a basic assertion library for JavaScript, a simple tool for supporting basic BDD and TDD development principles in your every day coding.

BDD stands for "Behavior Driven Development" and TDD for "Test Driven Development".

Chai is framework agnostic and can be paired with any other JavaScript testing framework, even working with Rails applications.

Since code testing is not the easiest task in Web development, Chai comes with lots of documentation to get developers started, along with its own programmatic API, and plugin repository for extending default functionality.
