Test-Driven JavaScript Development

"An essential reference for the social web, present and future a must-have for making your website known on the social graph.

For JavaScript developers working on increasingly large and complex projects, effective automated testing is crucial to success. Test-Driven JavaScript Development isa complete, best-practice guide to agile JavaScript testing and quality assurance with the Test-Driven Development (TDD) methodology. Leading agile JavaScript developer Christian Johansen covers all aspects of applying state-of-the-art automated testing in JavaScript environments, walking readers through the entire development lifecycle, from project launch to application deployment, and beyond.

 

Using real-life examples driven by unit tests, Johansen shows how to use test-driven development (TDD) principles to gain greater confidence in your code base, so you can fearlessly refactor and build more robust, maintainable, and reliable JavaScript code at lower cost. Throughout, he addresses crucial issues ranging from code design to performance optimization, offering realistic solutions for developers, QA specialists, testers, and other software professionals.

 

Coverage includes

• Understanding the concepts of automated tests, TDD, and unit testing
• Building effective automated testing workflows
• Choosing the right unit testing framework for your needs
• Writing more modular and testable code
• Testing code for both browsers and servers (using Node.js)
• Using TDD to build cleaner APIs, better modularized code, and more robust software
• Using test stubs and mocks to test units in isolation
• Continuously improving code through refactoring
• Walking through the construction and automated testing of fully functional software
• Writing superior unit tests
