Since GSoC is over now, I integrated the “Automated webapp tests for MyFaces core and extensions”-project done by Cosmin Martinconi into the MyFaces codebase.
This test framework uses Arquillian to automatically configure and start a container (e.g. Tomcat or Jetty), to deploy the test cases on it and to execute them and run assertions using HtmlUnit and a JSF-PhaseListener. Currently this already works, however with a very limited set of features (and stability). You can check out a working example at https://svn.apache.org/repos/asf/myfaces/gsoc/webapptest/examples/simple
The project currently lives in the gsoc folder at https://svn.apache.org/repos/asf/myfaces/gsoc/webapptest and has its own component in the MyFaces test issue tracker (“webapptest“). In addition Cosmin created a wiki page showing the current state of the project (see http://wiki.apache.org/myfaces/AutomatedWebappTest_Status).
The MyFaces community already showed great interest on this project and I think we will be able to do a first alpha release of it in the near future. Afterwards MyFaces Webapptest will be used on MyFaces core and its subprojects to provide a fast and easy way of doing integration testing within a JUnit test case.
