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. Get an overview of both test-driven and behavior-driven development Write useful specs by determining what you need to test—and what you don’t Test the behavior of new and existing code against the specs you create Apply Jasmine matchers and discover how to build your own Organize code suites into groups and subgroups as your code becomes more complex Use a Jasmine spy in place of a function or an object—and learn why it’s valuable

What You Will Learn Basic TDD fundamentals, life cycle, and benefits Become acquainted with the concepts and elements of unit testing and writing basic unit tests for JavaScript Understand the way JsUnit, Qunit, Karma and DalekJs work Use the Jasmine framework Interpret feature detection and devise tests specific to cross-browser compatibility Integrate jsTestDriver with Eclipse and run tests with jsTestDriver Explore re-factoring, adding and notifying observers Understand test-driven development in case of server-side JS In Detail Initially, all processing used to happen on the server-side and simple output was the response to web browsers. Nowadays, there are so many JavaScript frameworks and libraries created that help readers to create charts, animations, simulations, and so on. By the time a project finishes or reaches a stable state, so much JavaScript code has already been written that changing and maintaining it further is tedious. Here comes the importance of automated testing and more specifically, developing all that code in a test-driven environment. Test-driven development is a methodology that makes testing the central part of the design process – before writing code developers decide upon the conditions that code must meet to pass a test. The end goal is to help the readers understand the importance and process of using TDD as a part of development. This book starts with the details about test-driven development, its importance, need, and benefits. Later the book introduces popular tools and frameworks like YUI, Karma, QUnit, DalekJS, JsUnit and goes on to utilize Jasmine, Mocha, Karma for advanced concepts like feature detection, server-side testing, and patterns. We are going to understand, write, and run tests, and further debug our programs. The book concludes with best practices in JavaScript testing. By the end of the book, the readers will know why they should test, how to do it most efficiently, and will have a number of versatile tests (and methods for devising new tests) to get to work immediately. Style and approach Easy-to-follow guide with suitable examples for developing JavaScript code in the test-Driven environment, with popular tools and frameworks. User experience and statements are also included to help readers make a better choice of tool for real-world projects.
