This is a quick incomplete set of instructions. More details to follow when Arnaud gets a chance 
Here is a quick tutorial to run those tests :
- Download canoo webtest from : http://webtest.canoo.com/
- Install Canoo in : C:/Program Files/Canoo/ (otherwise you will have to update properties\local.properties)
- CAS demo .war file should be deployed and available on https://localhost:8443/cas/
- the proxyCallBackTest application should be deployed twice (with different instances) on https://localhost/proxyCallBackTest1/ and https://localhost/proxyCallBackTest2/ (otherwise update properties\canoo.properties
Now launch build.xml file with the target all. Tests should pass
