How to replace a Managed Bean on-fly?

[yegor256]

This is what I'm trying to do:

public void testAuthenticatesUser() throws Exception {
  JSFSession jsfSession = new JSFSession("/");
  JSFClientSession client = jsfSession.getJSFClientSession();
  JSFServerSession server = jsfSession.getJSFServerSession();
  server.getFacesContext()
    .getExternalContext()
    .getApplicationMap()
    .put("authenticator", new MockedAuthenticator());
  String url = WebConversationFactory.getWARURL() + "/auth?login=test&pwd=3737";
  WebClient web = jsfSession.getWebClient();
  web.getPage(url);
}

The idea is replace "authenticator" application-scoped managed bean with a mocked object. This object won't do real-life requests to LDAP, but will just return "true". The problem is that the example above doesn't work. Am I doing it right?

I think this is the wrong approach.  I doubt that you will ever get it to work that way even though if you could it might be a little cleaner than what I'm about to suggest.

Instead,  add a ServletContextListener to your test WAR.  The SCL would set up your mock authenticator.  If you are using a Servlet 3.0 contianer then you could put this in its own jar and declare it with a web-fragment.xml.  That would be a pretty clean way of doing it.  You just include that jar when you are testing.

Hm.. I have an impression that JSFUnit is going to let me control my context entirely, including getting and setting managed beans (and their properties). Isn't it true? If I have to deal directly with Servlets why would I need JSFUnit on top of HttpUnit than?

Are you sure that I can't do what I'm trying to do with JSFUnit only?

I thought of another way.  Use an InitialRequestStrategy.  From an InitialRequestStrategy, the only server-side artifact you can get to is the HttpSession.  You can get that via WebConversationFactory.getSessionFromThreadLocal().  From there you can call HttpSession.getServletContext().setAttribute() to insert your Mock.

Make sure you do this within the InitialRequestStrategy.  You want this to happen before the call to new JSFSession().

Stan, many thanks. Now it works perfectly: http://trac.fazend.com/rempl/browser/rempl/trunk/rempl/rempl-oss/src/test/java/com/rempl/oss/helpers/HomeXhtmlTest.java?rev=604&marks=36-59
