End to end testing is a very common testing methodology where the objective is to test how an application works by checking the flow from start to end. Not only the application flow under dev environment is tested, but the tester also has to check how it behaves once integrated with the external interface.

HtmlUnit is a "GUI-Less browser for Java programs". It models HTML documents and provides an API that allows you to invoke pages, fill out forms, click links, etc... just like you do in your "normal" browser. It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use. It is typically used for testing purposes or to retrieve information from web sites. HtmlUnit is not a generic unit testing framework. It is specifically a way to simulate a browser for testing purposes and is intended to be used within another testing framework such as JUnit or TestNG. Refer to the document "Getting Started with HtmlUnit" for an introduction. HtmlUnit is used as the underlying "browser" by different Open Source tools like Canoo WebTest, JWebUnit, WebDriver, JSFUnit, Celerity, ... HtmlUnit was originally written by Mike Bowler of Gargoyle Software and is released under the Apache 2 license. Since then, it has received many contributions from other developers, and would not be where it is today without their assistance.

$.extend({ myFunc : function(someArg, callbackFnk){ // do something here var data = 'test'; // now call a callback function if(typeof callbackFnk == 'function'){ callbackFnk.call(this, data); } } }); $.myFunc(someArg, function(arg){ // now my function is not hardcoded // in the plugin itself // and arg = 'test' });

Javascript Unit testing frameworks list with it's features and which one you should use.

specifically designed to help JavaScript and CSS folk test snippets of code, within some context, and debug the code collaboratively. JS Bin allows you to edit and test JavaScript and HTML (reloading the URL also maintains the state of your code - new tabs doesn't). Once you're happy you can save, and send the URL to a peer for review or help. They can then make further changes saving anew if required.

MooShell is a shell editor where you can write your JavaScript, HTML and CSS code and run it. It might prove to be useful in various cases where you need to test your code without reloading your browser.

How to use JQuery (or other libraries) in a bookmarklet! With an example of making textarea's resizeable. Chris Adams provides a template for creating your own bookmarklet and explains some of the reasons you might want to use this technique for development and testing. He also points out some gotcha's to be careful of.

SlimerJS is useful to do functional tests, page automation, network monitoring, screen capture, etc. SlimerJS is similar to PhantomJs, except that it runs on top of Gecko, the browser engine of Mozilla Firefox (specifically, version 31), instead of Webkit, and is not yet truly headless.

This OpenSocial application provides the ability to write and save JavaScript code samples to execute against OpenSocial containers. This helps rapidly test sample OpenSocial code. Code samples can be saved and loaded. You can give other developers links to code samples for instructional or debugging purposes.

This has been tested with Firefox 3.5.5, IE 8 (8.0.6001.18702), Google Chrome 3.0.195.33, and Safari (Win) 4.0.4 (531.21.10). For web spiders, no content is hidden from them so it matters not whether they support Flash or JavaScript.

Now Anyone can test your Javascript code by online Free Javascript Editor Tool. Javatpoint added a new feature in his javascript tutorial for beginners.

PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

Features: You can enter statements and expressions at the same prompt. The result of each non-void statement or expression is shown. User-defined variables. b = document.body User-defined functions. function f() { return 5; } JavaScript error messages are shown in red. Previous statements and expressions are available through Up and Down arrow keys. Tab completion. Multiline input (Shift+Enter to insert a line break). If the shell is opened using a bookmarklet, JavaScript typed into the shell runs in the context of the original window. Works well in Firefox, mostly works in Opera 8 and in IE 6 for Windows. Suggested uses: Test short bits of JavaScript, bookmarklets, or user scripts. (For longer bits of JavaScript, try the JavaScript development enviornment too.) Explore DOM objects such as document.body using props (Alt+P) to figure out what is possible. Explore the DOM of a specific page using the bookmarklet version of the shell. Modify the DOM of a specific page using the bookmarklet version of the shell. Use the shell like you would use the home screen of a calculator such as a TI-83. Alt+M gives you easy access to math functions such as sin and pow.

Minimal: original algorithm but keep linefeeds if single - Conservative: original algorithm - Agressive: remove more linefeed than the original algorithm but can be regressive
