Learn JavaScript test-driven development using popular frameworks
and tools About This Book * Learn the life cycle of TDD and its
importance in real-world application * Gain knowledge about popular
tools and analyze features, syntax, and how they help in JavaScript
testing * Implement test-driven programming exercises using the
practical code examples Who This Book Is For If you have an
intermediate knowledge of HTML, CSS, and JavaScript and want to
learn how and why the test-driven development approach is better
for your assignments, then this book is for you. 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.
