It’s wrong to assume that VuGen scripts are always written in C. Some virtual user types are only available in other languages, and some give you an option of generating a recorded script in a variety of languages. At current count, LoadRunner supports 8 languages (or 6, if you consider VBA, VBScript and VB to be the same language).

This post shows the list of languages available for LoadRunner/VuGen 9.10, and which vuser types they are available for.

To generate your script in a different language (if available), change the “scripting language” setting under Recording Options.

COM/DCOM Recording Settings - Scripting Language

It should be noted that not all vuser types allow you to generate code from a recording of your application. Template scripts require you to hand-code API calls in your script. This is not recommended unless the interaction between the client and the server is very simple – good examples would be performance testing of DNS or MAPI.

1 The Web (HTTP/HTML), SAP – Web, and Siebel – Web virtual user types can all be converted to a Java-based script. However, this requires that you are also licensed for the Java vuser type or the Java Record Replay vuser type. The Click and Script and Web Services vuser types cannot be converted to Java.

Note that the VB vuser type (which is a template virtual user that does not support Record/Replay) has some web functions available to it, such as web.url() and web.submit_data().

  1. Hi. In our company, we have two applications one is developed in Dot Net & MSSQL (DB) and another one is on JAVA & DB2 (DB).
    Both are webbased applications.

    1. What kind of protocols I have to select in HP Load Runner. Just Web(HTTP/HTML) ??
    2. What language I have to use. Just C language or can I use VB Scripting.
    3. How can I identify what kind of protocols need to be selected before recording a script in HP Load Runner.

    Thanks in advance for all your valuable time.

  2. Hi,

    On what basis do we select the Scripting language, is it Application dependent?

    Also I see the above comparison, which says we cannot Record/Replay when applications are based on EJB/CVuser etc are used.
    a) What does it mean?
    b) As per my understanding Load Runner is used to Record/Replay with little manual interference for instances like Correlation/Parameterization. Could please help me to understand the usage of Load Runner better? Do we manually write scripts as per the above scenario?

    Thanks.

    Regards,
    Sonia

  3. I am trying to suppress a call to a url which is making my script fail. There should be a function which suppresses the call to a URL that I can put in the script but I cannot find it. I know I can comment out the url if I record the script in the URL mode but I can’t use that mode for all my scripts. In Silk Performer there is a way to suppress the call to a url, is there same in LR? Also tell me how can i start new post.
