By now, everyone knows about Test-Driven Development and unit testing. But are you using the testing frameworks to their fullest? In this tutorial, I’ll introduce you to some of the more advanced techniques available to you. As this tutorial will cover some advanced topics, I assume you’ve already created unit tests before and are familiar with the basics and its terminology. If not, here’s an excellent article to you get started: TDD Terminology Simplified. We’ll be using SinonJS. This is a standalone framework which provides an API for mocks, stubs, spies and more. You can use it with any testing framework of your choosing, but for this tutorial, we’ll be using BusterJS, as it ships with SinonJS built-in.

When we talk about a JavaScript engine what we’re usually referring to is the compiler; a program that takes human-readable source code (in our case JavaScript) and from it generates machine-readable instructions for your computer. If you haven’t considered what happens to your code when it runs this can all sound rather magical and clever but it’s essentially a translation exercise. Making that code run fast is what’s clever.

The following content comes from the second module of my Pluralsight course entitled: Front-End First: Testing and Prototyping JavaScript Apps. The rest of the course covers an introduction to Unit Testing,Mocha (a JavaScript test runner), Grunt (a JavaScript task runner),Sinon.js (a mocking and spying library), Mockjax (a way to mock Ajax requests), mockJSON (a way to generate semi-random complex objects for prototyping), and more.

There are a lot of programming languages, but there is only one that runs in your web browser, and that’s Javascript. Ruby, Java, C#, Python, PHP and dozens more are used to write software for the web but in the end they all produce HTML and Javascript, and HTML is not a programming language. That means that there’s only one programming language for the web, and that’s Javascript. If you’re writing software for the web, you’re programming in Javascript, it’s just a matter of how many layers of “comfort zone” there is between you and your application.

Venus.js in an open source software testing tool developed by LinkedIn that allows you to organize and run your entire JS testing system with a single tool using Node.js. Venus eliminates repetitive tasks and friction points and lets you focus on writing tests instead of running them.

It’s a myth that if you use a client side MVC framework that your application’s content cannot be indexed by search engines. Search engine visibility does, however, require a little more work to implement. This is a real trade off you’ll have to consider before you decide to go with an MVC framework instead of an application that does its rendering on the server side. Before you get scared off: I’d like to point out that our search engine code was done by Sam Saffron in a day! This extra work might take you less time than you thought.

JavaScript evolves at a really fast pace. With such a big wave of fresh JavaScript technology splashing the web everyday it's a daunting task to keep up to date with all of it.
Jan Hesse's insight:
JavaScript evolves at a really fast pace. With such a big wave of fresh JavaScript technology splashing the web everyday it's a daunting task to keep up to date with all of it. jQuery is the preferred library due to its undeniable popularity, although some scripts are written in pure JavaScript. In this article we are going to cover 10 useful scripts that will save you some time when solving common problems. Most of these snippets are good to copy & paste but feel free to analyze, strip, mix, share, or adapt them to your own workflow.

Cargo-cult programming is what a programmer does when he or she doesn't know a particular language or paradigm well enough, and so ends up writing redundant and possibly harmful code. It rears its head quite often in the land of JavaScript. In this article, I explore the concept of cargo-cult programming and places to watch out for it in JavaScript. Cargo-culting is sometimes defined as "the extreme adherence to the form instead of content." The form, in programming, being the syntax, paradigms, styles and patterns that we employ. The content being the abstract thing that you are seeking to represent through your code — the very substance of your program.

The main principle with Object Oriented Programming (OOP) is the use of Classes (Functions in JavaScript) to create objects, and that objects are implemented in a manner that allows them to adopt Inheritance, Polymorphism, and Encapsulation. We are only concerned with Inheritance and Encapsulation, since only these are applicable for OOP in JavaScript. Essentially, objects can encapsulate functionalities and inherit methods and properties. The rest of this article will focus on using objects in JavaScript in an object oriented manner—with inheritance and encapsulation—to easily reuse code in our applications and abstract functionalities away into specialized objects. We will focusonly on the best two techniques [1] for implementing OOP in JavaScript.

Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style. “Style” covers a lot of ground, from “use camelCase for variable names” to “never use global variables” to “never use exceptions.” This project holds the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project. Click here to edit the title
