Thanks for the tip Greg. I quickly went through the debugger based on
the example here:
http://depressedprogrammer.wordpress.com/2007/06/18/unit-testing-struts-2-actions-spring-junit/
and I learned two things.
1. execute() does call getSettings(). All that CRUD nonsense was me
not being sure it was actually calling the method I wanted because it
threw an exception upon execution.
2. It looks like adding the following to the createAction(..) method
fixed my first problem. I had an interceptor putting a variable on the
session, but no session was set, triggering a NullPointerException.
proxy.getInvocation().getInvocationContext().setSession(new HashMap());
Now I'm just running into a problem where the
TilesAccess.getContainer(servletContext) is returning a null. This is
in the org.apache.struts2.views.tiles.TilesResult class.
public void doExecute(String location, ActionInvocation invocation)
throws Exception {
setLocation(location);
ServletContext servletContext =
ServletActionContext.getServletContext();
TilesContainer container = TilesAccess.getContainer(servletContext);
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
// fails because the container is null
container.render(location, request, response);
}
I will post my final results when I get that part figured out. If
someone can offer a tip, I'd appreciate it. I'm learning as I go here.

You can take a look at this:

I've used it to unit test actions all the way through interceptors,
validation, actions, and results including freemarker result types.

I had tried using proxy.execute(), which will use Struts. Maybe that's
where I'm a bit lost. I don't implement execute() because of my CRUD
approach.
Can someone point me to some appropriate struts 2 junit tests so I can
figure this out?
