To run Gengar you need:

Java     -> https://java.com/en/download/
Selenium -> http://www.seleniumhq.org/download/

With Selenium installed, make it run with:

java -jar selenium-server-standalone-2.45.0.jar

If running headless, you'll need Xvnc or Xbnc. If using Xvnc, you should run:

export DISPLAY=:$(id -u)
nohup Xvnc -ac -SecurityTypes None $DISPLAY & > /dev/null

And then run your tests with:

node runner.js

tests/viewName/
	-> viewName.view.js
	-> componentName.component.js

images/
	-> viewName.stateName.[base/diff/current].png
	-> componentName.stateName.[base/diff/current].png
	-> componentName.stateName.diff

new Gengar('viewName', (g, state) -> {
	state('stateName', () -> {
		// Actions
	});
});

*State will automatically take a screenshot of the whole page if not specified.

###Todo:

* [ ] Write some nice documentation.
* [ ] Improve this readme
* [ ] Allow for different language "interfaces" (Ruby, Go, Python, whatever)

###Done: * [x] Add image diffing with ImageMagick * [x] Add a web interface/viewer to see and manage differences * [x] Make everything installable through npm or some other package manager
