LoadRunner Testing Ajax

What is AJAX ?

Ajax, shorthand for asynchronous JavaScript and XML, was a web development technique for creating Interac tive Web applications. The intent is to make Web pages feel more responsive by exchanging small amounts of data with the server behind the scenes , so and the entire Web page does not has the to is reloaded each time the user requests a change. This was meant to increase the Web page's interactivity, speed, and usability.

The Ajax technique uses a combination of:

• XHTML (or HTML) and CSS, for marking up and styling information.
• The DOM accessed with a Client-side scripting language, especially ECMAScript implementations such as JavaScript and JSCRI PT, to dynamically display and interact with the information presented.
• The XMLHttpRequest object is used to exchange data asynchronously with the Web server. In some Ajax frameworks and in certain situations, an IFrame object are used instead of the XMLHttpRequest object to Exchan GE data with the Web server, and in other implementations, dynamically added <script> tags could be used.
• XML is sometimes used as the format for transferring data between the server and client, although any format would work, in cluding preformatted HTML, plain text, JSON and even ebml. These files may is created dynamically by some form of server-side scripting.

Like DHTML, LAMP and SPA, Ajax isn't a technology in itself, but a term that refers to the use of a group of technologies .

Json

JavaScript Object Notation (JSON) is a lightweight format for representing

Objects and their state. Major technology providers, such as Yahoo WS

and Microsoft ASP. Chosen JSON for client-server data exchange

As an alternative to XML, because it can is parsed more easily than XML.

For example, JSON objects can is de-serialized by simply passing them to the JavaScript evalfunction.

LoadRunner supported by AJAX Frame

LoadRunner supports less AJAX frameworks, and the following is excerpted from http://www.wilsonmar.com/ajax_rec.htm:

HP has stated this they support these frameworks for AJAX functions:

• • Atlas 1.0.10920.0/asp.net AJAX (All controls) (developed using Visual Studio 2005). LoadRunner 9.10 supported the Atlas 2.0 version in Visual Studio 2005.
    • This is one generation behind the ASP. 3.5 AJAX AjaxControlToolkit shown on the their sample website. However, I had been able to use LoadRunner 9.51 to work with many MS AJAX 3.5 controls Even though some controls is not Being created during recording.
  • Scriptaculous 1.8-autocomplete, Reorder List, and Slider

HP advertises that Vugen supports these frameworks at the "engine level", implying that Vugen would create Web Click and Sc Ript LoadRunner functions, but not LoadRunner ' s AJAX specific functions:

• • Prototype 1.6
  • Google Web Toolkit (GWT) 1.4

I ' ve heard that additional licensing was needed for LoadRunner to support the Infragistics Library. What's the HP product code for this, if it exists???

The supported frameworks for AJAX functions is:

? Atlas 1.0.10920.0/asp.net Ajax-all Controls

LoadRunner Test AJAX Examples of

Take ASP. NET AJAX online samples as an example:

Http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Slider/Slider.aspx

Test the Slider,loadrunner to record the script and call the Ajax_slider function to handle the behavior of the slider control:

Web_browser ("Slider.aspx",

DESCRIPTION,

ACTION,

"Navigate=http://www.asp.net/ajax/ajaxcontroltoolkit/samples/slider/slider.aspx",

last);

Ajax_slider ("Slider",

DESCRIPTION,

"Framework=atlas",

"Id=ctl00_samplecontent_slider1",

ACTION,

"Useraction=setvalue",

"Value=100",

last);

Execution JavaScript the method

Using the Web_browser function, you can execute JavaScript statements by assigning values to the Evaljavascript property, such as accessing the DOM, and using the Evaljavascriptresultparam property to save the results of the statement execution to parameters:

Web_browser ("Keyid_get",

ACTION,

"Evaljavascript=document.getelementbyid (/" ctl00_samplecontent_slider1_boundcontrol/"). InnerText;",

"Evaljavascriptresultparam=strvalue",

last);

Lr_output_message (Lr_eval_string ("{strvalue}"));
