POP-UP Recording Limitation in Jmeter

There are generally three kinds of popup-1. Alert box 2. Confirm 3. Prompt. These are Client side scripts/programs generated in the webpage. Since Jmeter is build to load test Servers it can’t record these popups generated during recording a site with Jmeter.

The limitation has also been cited in http://jakarta.apache.org/jmeter/

These are the supported reasons for this:

1. JMeter is not a browser: JMeter is not a browser. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it’s possible to view the response as HTML etc, but the timings are not included in any samples, and only one sample in one thread is ever viewed at a time).

2. The Proxy Server can only record HTTP traffic (any requests to server)

3. Does JMeter process dynamic pages (e.g. Javascript and applets)

JMeter does not process Javascript or applets embedded in HTML pages. JMeter can download the relevant resources (some embedded resources are downloaded automatically if the correct options are set), but it does not process the HTML and execute any Javascript functions.

If the page uses Javascript to build up a URL or submit a form, you can use the Proxy Recording facility to create the necessary sampler. If this is not possible, then manual inspection of the code may be needed to determine what the Javascript is doing.

I have tried verifying this with two methods. In first method I recorded the pop-ups in BADBOY tool and tried to export it to Jmeter. Secondly tried it with Jmeter itself.

Method1: (Exporting from BADBOY)

We record the Alert box and prompt from the below link: http://alokranjan.freehostia.com/pop/popup.htmlpop1

Now we save the script. And when we try to export it the following error comes.

pop2

It says items like Messagebox and alert box are not supported in Jmeter.

pop3

Method2. (Recording in Jmeter)

Site: http://alokranjan.freehostia.com/pop/popup.html

pop4

When we click on the write sth alert box it writes a line (this is a sample line) on the web page.

When we record the site only the page gets recorded and .The alert box and text output doesn’t get recorded.

pop5

This confirms that Jmeter can’t handle popups or client side scripts.
