Overview of this book

Node.js is a modern development stack focused on providing an easy way to build scalable network software. Backed by a growing number of large companies and a rapidly increasing developer base, Node is revolutionizing the way that software is being built today. Powered by Google's V8 engine and built out of C++ modules, this is a JavaScript environment for the enterprise.Mastering Node.js will take the reader deep into this exciting development environment. Beginning with a comprehensive breakdown of its innovative non-blocking evented design, Node's structure is explained in detail, laying out how its blazingly fast I/O performance simplifies the creation of fast servers, scalable architectures, and responsive web applications.Mastering Node.js takes you through a concise yet thorough tour of Node's innovative evented non-blocking design, showing you how to build professional applications with the help of detailed examples.Learn how to integrate your applications with Facebook and Twitter, Amazon and Google, creating social apps and programs reaching thousands of collaborators on the cloud. See how the Express and Path frameworks make the creation of professional web applications painless. Set up one, two, or an entire server cluster with just a few lines of code, ready to scale as soon as you're ready to launch. Move data seamlessly between databases and file systems, between clients, and across network protocols, using a beautifully designed, consistent, and predictable set of tools.Mastering Node.js contains all of the examples and explanations you'll need to build applications in a short amount of time and at a low cost, running on a scale and speed that would have been nearly impossible just a few years ago.

Headless website testing with ZombieJS and Mocha


Even though we are working on the server with Node, there is no doubt that much of what we are programming will affect those connecting to our services via a browser. As it is expected that we will be using Node to test our server-side code, why not integrate browser-side testing as well?

We'll dig deeper into how to unify the entire make/build/test/deploy chain in the next section. For now, let's look into the easy to use Mocha testing framework and how some simple browser testing can be done right from the server.

Note

The libraries we will use in this section and the next are available through the following sources:

PhantomJS: http://www.phantomjs.org/

Mocha

Mocha expects a directory containing testable units to contain a /test directory, within which exist various spec, or test specification and files, making up the suite of tests that...
