Get a concise introduction to Jasmine, the popular behavior-driven testing framework for javascript. This practical guide shows you how to write unit tests with Jasmine that automatically check for bugs in your application. If you have javascript experience—with knowledge of some advanced features—you’ll learn how to write specifications for individual components, and then use those specs to test the code you write. Throughout the book, author Evan Hahn focuses primarily on methods for testing browser-based javascript applications, but you’ll also discover how to use Jasmine with CoffeeScript, Node.js, Ruby on Rails, and Ruby without Rails. You won’t find a more in-depth source for Jasmine anywhere.
