"PhantomJS is a headless WebKit with JavaScript API. CasperJS is a navigation scripting & testing utility that runs on top/alongside of PhantomJS.

If you’re thinking “headless WebKit??!!?”, then it might be easier for you picture PhantomJS as a web inspector console that can be injected into any web page that you want, then accessed and used.

CasperJS makes it alot easier for you to navigate around a web page testing as you go. To be fair, my explanations don’t do these two tools enough justice. Please visit http://phantomjs.org/ and http://casperjs.org/ for a better explanation and more advanced features that aren’t covered here.

"I got fed up with QUnit which I was using to test the client side of one of my projects. It proved to be very unreliable when it came to async handling. I looked around for alternatives and to my surprise, I couldn't find anything more satisfying than what I was already using. Then came the idea: What if I'd write my own Unit Testing framework for JavaScript?"

"So how does a TDD test differ from a unit test? Unlike a unit test, a TDD test is used to drive the design of an application. A TDD test is used to express what application code should do before the application code is actually written."

"a JavaTM load testing framework that makes it easy to run a distributed test using many load injector machines. It is freely available under a BSD-style open-source license.

The latest news, downloads, and mailing list archives can be found on SourceForge.net.

Key features
Generic Approach Load test anything that has a Java API. This includes common cases such as HTTP web servers, SOAP and REST web services, and application servers (CORBA, RMI, JMS, EJBs), as well as custom protocols.
Flexible Scripting Tests are written in the powerful Jython scripting language.
Distributed Framework A graphical console allows multiple load injectors to be monitored and controlled, and provides centralised script editing and distribution.
Mature HTTP Support Automatic management of client connections and cookies. SSL. Proxy aware. Connection throttling. Sophisticated record and replay of the interaction between a browser and a web site."

JSDev is a simple JavaScript preprocessor. It implements a basic macro
language that is written in the form of comments. These comments are
normally ignored, and will be removed by JSMin. But JSDev will activate
these comments, replacing them with executable forms that can be used to do
debugging, testing, logging, or tracing. JSDev scans a source looking for
and replacing patterns. A pattern is a slashstar comment containing a
command and some stuff, and optionally a condition wrapped in parens.
There must be no space between the slashstar and the <cmd>.

"Recently I decided to start doing JavaScript code katas. I've been using JavaScript for around ten years, but there there are still a lot of aspects I don't know well or that I could use more practice in. Case in point, I had never used a unit testing framework with javascript. Having never unit tested JavaScript before, I used a scientific tool to carefully select from amongst the numerous unit testing packages available."

"A simplified explanation of the problem is that we violated the Single Responsibility Principle. So, we're going to use standard object oriented techniques to separate the concerns of our model logic.<br />
<br />
Let's look at the first example I mentioned: logging the creation of a user. <br />
<br />
To decouple the logging from the creation of the database record, we're going to use something called a service object. A service object is typically used to coordinate two or more objects; usually, the service object doesn't have any logic of its own (simplified definition). We're also going to use Dependency Injection so that we can mock everything out and make our tests awesomely fast (seconds not minutes). "

" A JavaScript shell allows you to quickly test snippets of JavaScript code without having to reload a web page. They are extremely useful for developing and debugging code."

"Real-time: Developers can observe DOM modifications as they happen inside the browser without the need to step through JavaScript code with a debugger or pause the execution of their application.Easy to use: With built-in security heuristics and nested views, both advanced and less experienced developers and testers can quickly spot areas of the application being tested that need more attention.Easier collaboration: Enables developers to easily export and share captured DOM modifications while troubleshooting an issue with their peers."

"Watir, pronounced water, is an open-source (BSD) family of Ruby libraries for automating web browsers. It allows you to write tests that are easy to read and maintain. It is simple and flexible. Watir drives browsers the same way people do. It clicks links, fills in forms, presses buttons. Watir also checks results, such as whether expected text appears on the page. Watir is a family of Ruby libraries but it supports your app no matter what technology it is developed in. They support Internet Explorer on Windows, Firefox and Chrome on Windows, Mac and Linux and Safari on Mac."

"Testing code that talks to the Twitter Streaming API is hard. The are 8 documented failure HTTP response codes, random disconnections, and second-to-second rate changes. And, since this is Twitter we’re talking about, basically anything can happen at any time – including complete downtime. So, let me introduce you to mockingbird. Mockingbird is a simple streaming HTTP server written in Ruby that you can use in place of the server at stream.twitter.com when you’re testing your Streaming API code. With mockingbird, all it takes is a few lines of code and you can simulate all the issues I described above and more."

"Are you developing jQuery hotness so fast that the slow-poke server team can't supply you AJAX services fast enough?  If so, you might be interested in the JavaScriptMVC-extracted jQuery.Fixture plugin.  Fixtures simulate AJAX responses so you can keep developing JavaScript functionality even if the server's services aren't working.  The fixture plugin is easy to setup and remove once the services are online."

REST Describe & Compile is an editor and a compiler for (REST) Web Services that are described in Sun engineer Marc Hadley's Web Application Description Language, or short WADL. In order to use REST Describe & Compile you do not necessarily need to understand what WADL is, it is a good idea to have heard at least of the basics though. In consequence, in the following let me explain the absolute minimum of what I consider good to know.

"XSS scanner tool that’s written in Javascript called XSS Rays for Microsoft. They have given me permission to release the tool as open source which is awesome because it can be used for other open source applications. I recommend you use it as part of the web development process to make sure you’ve filtered XSS correctly on your application. It works as a bookmarklet and scans any links, paths or forms on the target scanning page (even cross domain). You can add vectors to it quite easily and it includes some of the most common injections I’ve found on sites over the years. I’ve tested it on IE7/IE8 and Firefox but it could work in other browsers."

"These bookmarklets let you see how a web page is coded without digging through the source, debug problems in web pages quickly, and experiment with CSS or JS without editing the actual page."

"a free set of web tools to help anyone determine if their net connection is blocking or throttling BitTorrent or otherwise limits their bandwidth. The Glasnost tool determines how your ISP is handling BitTorrent traffic and gives a readout on whether it's being denied, throttled, or otherwise impaired. Network Diagnostic Tool covers other problems that might affect your upload or download speeds. And the Network Path and Application Diagnosis tries to reveal the routing, network tools, and other "last mile" issues that affect net performance. The tests are fairly simple, and each seems to require a working Java plugin to run. The Glasnost test, for instance, creates a fake BitTorrent stream between your connection point and the test's servers, then monitors what happens to the packets.

"provides developers with a JavaScript library for doing any number of A/B tests on a site (tweaking CSS, JavaScript, or HTML elements) all trained over time using a Genetic algorithm backend. This means that no matter how many different A/B tests you have on a page the genetic algorithm will adapt to the input (users visiting the page and hopefully achieving some pre-defined goal) and slowly show a more-optimal page layout to the user."
