I would like to headless "render" a webpage in different versions of browser. Lets say I want to render a page in IE 6,7,8,9,10 and then get the image of it.
I was playing around with selenium but if I understand corectly I have to install all the versions of IE and then driver just runs this browsers and report the result.
Are there any headless browser that support different versions of a web browser (render engine) ?
You can do it with Selenium Grid. You must prepare few systems with all IE wersion (or other browsers), connect them to grid, and run test for all browsers. If you have strong machine, you can use VirtualMachines for that, otherwise you must set few real machines.
