Gatling and a HTML5 app running against SAP

Gatling (Open-Source)

I have been given the great task of trying generate a Gatling script against a HTML5 app that queries SAP.
Using Gatling recorder I have achieved the following script:

`

My question is would gatling work with this technology? a HTML5 app using ajax-calls? Looking at the script it seams like this should work and replaying it does not gives me any errors.
Just to generate load, maybe this would work? Or do I need to use a tool that actually uses the entire DOM to test HTML5.
BTW: The HTML5 app runs through Soti Mobicontrol.

Cheers

Hi,

You can’t perform a load test on a javascript application with Gatling. You can however reproduce it’s ajax calls and do a load test on it’s backend, which is what your script is doing and what you recorded.

If this was your intention, sure, it will work!

Cheers,
Guillaume.

Ok, thanx Guillaume!
I want to crate traffic on the backend (using the frontend)
Just a control question:

given a part of my script:

`
.post(uri1 +
"/neptune/native/neptune_ajax?ajax_id=GET_CARTS_TOTAL&ajax_applid=UI5_RETAIL_CREATE_PO&field_id=00309&ajax_value=undefined")

`

This http-post will actually create load by executing some ajax-call that will hit the backend, which is my intention.
