LoadRunner - New VuGen

VuGen is based is an open source IDE called SharpDevelop (similar to Visual Studio .NET).
The SharpDevelop IDE will be the basis for several of HP’s software testing products, including QuickTest Pro, Service Test, and Service Virtualization Designer.
Being an IDE for .NET languages meant that HP had to do a lot of work to make it support C, and to integrate the existing recording and script generation functionality. Some old user interface components from VuGen like the Parameter and Runtime Settings windows have been re-used, but the majority of the user interface has been refreshed. It should be noted that the scripts that are created with VuGen 11.50 are still much the same as those created with VuGen 11.00. The scripts still have the same files and directory structure, and they are still run by the mmdrv.exe interpreter. It is just the development environment that has changed.
Some things that you will notice:
New user interface. SharpDevelop has given HP a lot of nice functionality here like dockable windows, code completion, etc.
New program icons, new syntax highlighting colours
Tree View has been removed, replaced with Step Navigator
A debugger for C has been added, which should give better visibility of the code than just the parameter values and log messages that were visible at runtime previously

Enhancements to Web vusers

  • Better support for Ajax polling types, including Poll, Long Poll and Push
  • Improved correlation studio, which will no longer require you to replay before finding correlations.
  • A Data Format Extension (DFE) has been added for Google Web Toolkit (GWT). This makes the serialized RPC data easier to read and correlate.
  • VuGen has been further improved and enhanced to provide a more reliable, flexible and customizable user experience.
  • Enhancements include:
  • Snapshots – A new compare snapshot feature that enables you to split the snapshot pane and view and compare the record snapshot with the replay snapshot.
  • An improved Summary Report – That now includes detailed information from all iterations.
  • Design Studio – Improved correlation functionality including:
  • A discard to correlation feature that enables you to delete the selected dynamic values from the correlation grid when a dynamic value has a status of new.
  • Design Studio supports correlation for the RTMP/T protocol.
  • Conditional Breakpoints – Enhanced conditional breakpoints functionality.
  • Thumbnail Explorer and Thumbnails – The new Thumbnail and Thumbnail Explorer features enable you to follow the recorded business process in a visual manner. The Thumbnail Explorer feature enables you to navigate to a location in the editor based on a visual representation of a step. You can also navigate in the Editor and view the corresponding visual content of the step in the Thumbnail Explorer.


  • There is now a TruClient for Internet Explorer, so it will now be possible to use TruClient on IE-only web applications. Note that this still just includes HTML + JavaScript websites; it does not mean that this vuser type suddenly supports ActiveX objects (or Flash, or Java Applets, etc.).
  • TruClient IE is less mature than TruClient Firefox, it is approximately feature-equalvalent to the version of TruClient that shipped with LoadRunner 11.02 (Feature Pack 2).
  • TruClient IE was developed as an add-in for IE 9, so will not work on earlier versions of IE. This version of IE was the first version to expose enough of the DOM to be usable by a TruClient-style vuser. Note that your web application must support IE9 in “standard mode”.
  • Some features have also been added to TruClient Firefox. These include:
  • The ability to specify think time
  • The ability to set HTTP headers
  • URL filters
  • Event handlers, which can automatically handle intermittent pop-up windows, etc.
  • Web page breakdown graphs have been added to TruClient (visible in LoadRunner Analysis). Previously they were only available for standard web vusers.

Ajax TruClient

  • Ajax TruClient has been significantly enhanced as follows:
  • Ajax TruClient for IE Client – The Ajax TruClient for IE now supports a wealth of new features in-line with the support previously provided for the Ajax TruClient for FF client. For example, function libraries and event handlers.
  • Ajax TruClient now has an improved and more user friendly user interface.
  • Additional JavaScript APIs have been provided.
  • TruClient Engine – The engine has enhanced performance, and improved heuristics have been implemented.
  • A new replace with parameter feature has been added.
  • Ajax TruClient documentation is now more intuitive and feature specific.

Improved Correlations

  • Correlation capabilities have been improved with the following:
  • An argument has been added to the web_reg_save_param_xpath API that instructs the query to return the entire content of the selected node, and not just its value.
  • The web_reg_save_param_regexp API now allows you to enter multiple capture groups in the regular expression and specify which capture group to save.You can also now save the entire matched expression.
  • New out-of-box correlation rules for ASP.NET.
  • You can now change the boundaries/regular expression/Xpath before correlating.
  • Correlation studio can now also correlate the RequestUrl argument


Other Enhancements

  • Better support for Adobe Flex
  • A new “RTMP” protocol has been added. Real Time Messaging Protocol (RTMP) is a protocol developed by Macromedia for streaming audio, video and data over the Internet, between a Flash player and a server.
  • LoadRunner now integrates with Service Virtualization, but I haven’t seen this in action yet.
  • The .NET Record-Replay vuser type now supports .NET 4.
  • LoadRunner can now generate load using IPv6. This includes IP Spoofing.
  • VuGen can now record 64-bit applications
  • Administrator Right Restrictions - Virtual User Generator (VuGen) and Analysis can now be run without Administrator privileges.
  • Expanded Data Format Extension Enhancements (DFE) Support
    • DFE support for the following has been added:
    • Binary XML DFE that transforms Microsoft WCF binary XML into XML format.
    • Remedy DFE that transforms Remedy request data into XML format
    • XSS DFE that enables you to test sites that use Cross Site Scripting (XSS) defense code.
  • Enhanced Web HTTP/HTML Protocol Support
    • Web HTTP/HTML protocol has been enhanced as follows:
    • A new web_set_pac API that enables you to change the PAC setting from within the script.
    • The web_set_user API has been enhanced. Now if an empty string (“”) is passed for host:port, the username and password in the current web_set_user call are applied to all domains unless a different user and password has been set for the domain with another web_set_user call.
    • The maximum number of concurrent connections to the server is automatically configured based on the User-Agent string.
    • JavaScript Engine – New functionality has been added that enables you to run JavaScript code in Web HTTP/HTML scripts.
  • Flex Enhancements
    • New support for AMF polling and long polling. This allows the recognizing and replaying of Polling and Long Polling in flex_amf_call steps in Flex Vuser scripts. (This is a correction to the corresponding line in the core documentation What’s New).
    • RTMP/T now supports automatic correlations (Studio, rules, Response based correlations).
    • The flex_rtmp_receive_stream and flex_rtmp_tunneled_send APIs now allow you to specify a time after which a script will continue to the next step.
  • Enriched Citrix Support
    • Citrix support has been expanded as follows:
    • XenApp enhancements:
    • The following APIs have been added – Ctrx_Logoff: Closes the current Citrix session, and Ctrx_Get_Server_Name: Returns the Citrix server name.
    • Support for XenApp 6.5 has been added.
    • ICA file adjustment – Enables support engineers to tweak the ICA files received during Citrix ICA + NFuse recording/replay without having to make changes on the Citrix Server Web Interface level.
    • Support for Citrix XenDesktop has been added.
    • Citrix Access Gateway support: LoadRunner supports CAG for Citrix Client version 10.200 (or less) and Citrix Client version 13.x.
  • IPv6 Support
    • The following IPv6 support has been added to the currently supported monitors and utilities:
    • NDM (Network Delay Monitor)
    • Webtrace
  • Java over HTTP (JOH) enhancement - Asymmetric java objects traffic support has been added.
  • Oracle NCA - Support for Oracle forms 11 has been added


  • Analysis has been enhanced as follows:
  • SQLite – New support for SQLite embedded database has been added. SQLite supports a load results database of up to 32 TB.
  • Color Palette – A new color palette feature has been added, enabling you to specify up to 100 colors, and to select colors that are associated with graph entities.
  • Analysis Graphs – You can now add graph notes to rich reports.
