steps for recording the selenium events on jmeter proxy

Question

I am presently working on a project for which selenium scripts are prepared and i want my jmeter proxy should record the steps executed by selenium browser. I tried running selenium and jmeter proxy server on same port but while doing that proxy server of jmeter refuse to start on same port. I read somewhere that this is possible but i am not getting the steps needs to follow.

You should do the same what you will do for simple test recording through Jmeter proxy:

1. setup Jmeter HTTP Proxy Server;
2. start configured Jmeter Proxy;
3. configure and enable proxy settings in your test browser (used by selenium) to use Jmeter Proxy.

Then run your selenium tests as usual, via configured test browser - HTTP Proxy Server will record execution.

To exclude all the steps performed in the "selenium-server" window try to add the following to 'URL Patterns to Exclude' in HTTP Proxy Server settings:

^/selenium-server/.*

Useful point here is to separate recorded execution into different Thread Groups - e.g. separate Thread Group in Jmeter for each recorded selenium testcase.

Step-by-step guideline you may found here.

To tell the truth such the "re-recording" may appear not very useful and effective: JMeter is not a browser, and does not interpret the JavaScript in downloaded pages.
As per Jmeter wiki:

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.

So if you need Jmeter possibilities to implement load/performance-testing based on existent Selenium functional scripts better for you then use run Selenium scripts from Jmeter.
