Selenium HQ Review

I can easily integrate with TestNG and Maven. Also I am able to set servers and hubs to execute my test case against

I can run a set of regression test cases with every release to QA.

I would like to be able to capture HTML header information but I have not been able to do that yet

I've used it for three years.

There were no issues during deployment.

Currently WebDriver is having issues running against the latest of Firefox.

There have been no issues scaling it out.

There is none yet there is a lot sites where questions can answered.

I used Capybara. I am more familiar with Java

It was pretty straightforward. It needs some degree of programming knowledge.

We did it in-house.

It's free.

Go for it. This is one of the best open source solutions I know of.
