I have been using Selenium/Webdriver for functional testing in a grid setup. We are in the process of transitioning to a Solr based search service. I already have Solrmeter for load testing the Search engine core, load UI for load testing the Rest-ful service. We also would like to load test the entire end to end service chain, i.e
User interface -> Restful service -> Solr core.
My boss wants me to use Selenium/WebDriver for this end to end load testing so that it becomes integrated with our core testing framework.
I am skeptical about it because WebDriver does not have supporting tools for load testing. The easiest way I can think of doing it in Selenium/WebDriver is to code timestamps in my scripts at the time when the query is sent and when the results are displayed on the webpage. Then write some reporting mechanism to gather and display reports. Also I imagine selenium would be slower.
On the other hand members from the stackoverflow community have suggested using JMeter for the same which I assume is less of an hassle. Can somebody give me pros/cons of Selenium/WebDriver Vs JMeter for load testing in this scenario?
