About this product

One skill that’s essential for any professional JavaScript developer is the ability to write testable code. This book shows you what writing and maintaining testable JavaScript for the client- or server-side actually entails, whether you’re creating a new application or rewriting legacy code. From methods to reduce code complexity to unit testing, code coverage, debugging, and automation, you’ll learn a holistic approach for writing JavaScript code that you and your colleagues can easily fix and maintain going forward. Testing JavaScript code is complicated. This book helps you simply the process considerably. Get an overview of Agile, test-driven development, and behavior-driven development Use patterns from static languages and standards-based JavaScript to reduce code complexity Learn the advantages of event-based architectures, including modularity, loose coupling, and reusability Explore tools for writing and running unit tests at the functional and application level Generate code coverage to measure the scope and effectiveness of your tests Conduct integration, performance, and load testing, using Selenium or CasperJS Use tools for in-browser, Node.js, mobile, and production debugging Understand what, when, and how to automate your development processes That’s right: JavaScript code is testable, despite the lack of unit test standards for this language. With this book, you’ll discover how to devise excellent tests and real-world testing plans for your existing JavaScript code. Developers starting out on a new project will greatly benefit from these guidelines. Testing a language that runs within many different implementations and environments is inherently difficult-and since most JavaScript environments are UI-based, automated testing becomes even more difficult. This guide shows developers and their managers how to overcome these problems to test JavaScript code efficiently. Topics include: Which types of Javascript testing are most effective When and why should you run tests on Javascript code Code patterns and anti-patterns that promote and inhibit Javascript testing Integrating unit tests with your development and build environments (automated test running and reporting) Code coverage: how to get it, interpret it, and automatically generate it
