Visual/CSS regression testing

The sub module drulenium_visual_regression helps in Automating Visual/CSS regression testing.
Concept:

• The system takes Image screenshots of web pages, before you make changes like site upgrades to your site.
• The system takes another set of Image screenshots of web pages, after you make changes
• The system calculates the difference of image pixels that changed and generates an animated GIF to look at

Sample GIF:

How drulenium_hosting_client submodule works without installing selenium locally?

• The Configuration (like site domain & pages to test, user name, password & email...) are sent to Remote Drulenium server through XML-RPC
• Remote server uses the Configuration to process the request, takes snapshots and generates Comparison reports which are fetched by local Drulenium module
