Re: Cross browser performance test with Load Runner

[James Pulley]

This is a functional test not a performance one.  You need to have a better understanding of the OSI model and how loadrunner virtual users map over the top three layers.   In short, I you had classroom instruction you should seek your money back

Web/http virtual users by default do not run a browser.  They simply reproduce the requests through the bottom of the session layer which would have come from a real browser.   The only time a server cares is when you have conditional page generation based upon browser type, the announcement string in the run time settings.    Other than that the server really couldn't care less about the browser so long as the security handshake is ok, standards compliant requests are generated for the browser to process and the client can process standard formatted responses.  

If you are forced down this path then you have several items coming into play 

• people who don't understand your tools, processes, procedures, etc.. are direction what and how you do your testing.  This is an absolute anti pattern for failure

• you will be moving virtual users to GUI, Citrix or RDP models.   You Willie the triple your time needs for development and debugging plus your infrastructure costs for load generation will likely increase by several orders of magnitude and complexity

Hello,

There is a requirement that Customer wants to do Cross browser performance test with Load Runner.

Can you please let me know how feasible is doing Cross browser with LR?

What are the different browsers does LR support for scripting and execution? Does LR support different browsers like Chrome, Safari for these activities?

I know in Runtime settings there is option to change the browser. But I think it only changes the browser type information to the server or will it actually simulate different browser?

If anyone of you have faced the similar situation please get me some lead on this.

Thanks in Advance

Regards,

Sharath
