Testing a servlet's init method

[Matt Raible]

I am trying to use Cactus to verify that a servlet's init-params from
web.xml has been loaded correctly.  I have setUp and my testInit
seemingly coded correctly.  When this servlet loads at the start of the
application, the parameters load fine (they're printed out by log4j),
however, when it's called from the test case, all values are null, and
test fails, since my servlet checks for null.

    protected void setUp() throws Exception {
        // JUnitDoclet begin method testcase.setUp
        super.setUp();
        servlet = new LoginServlet();
        servlet.init(config);
        // JUnitDoclet end method testcase.setUp
    }

    public void testInit() throws Exception {

        // Call method to test
        servlet.init();

        // check all parameters from web.xml
        String authURL = config.getInitParameter("authURL");
        assertTrue(authURL != null &&
authURL.equals("j_security_check"));
        assertEquals((String) servlet.getServletContext()
                .getAttribute(Constants.HTTP_PORT), "8080");
        assertEquals((String) servlet.getServletContext()
                .getAttribute(Constants.HTTPS_PORT), "8443");
        assertEquals((Boolean) servlet.getServletContext()
                .getAttribute("secureLogin"), Boolean.FALSE);
        assertEquals((String) servlet.getServletContext()
                .getAttribute(Constants.ENC_ALGORITHM), "SHA");
    }


When tomcat starts:      

     [java] DEBUG [main] [org.apache.webapp.actions.LoginServlet]
LoginServlet.init(129) | authURL: j_security_check
     [java] DEBUG [main] [org.apache.webapp.actions.LoginServlet]
LoginServlet.init(130) | Use SSL for login? false
     [java] DEBUG [main] [org.apache.webapp.actions.LoginServlet]

ssword? false
     [java] DEBUG [main] [org.apache.webapp.actions.LoginServlet]

LoginServlet.init(147) | HTTP Port: 8080
     [java] DEBUG [main] [org.apache.webapp.actions.LoginServlet]
LoginServlet.init(148) | HTTPS Port: 8443

When called by junit task in ant:

     [java] DEBUG [HttpProcessor[8080][0]]
[org.apache.webapp.actions.LoginServlet] LoginServlet.init(129) |
authURL: null
     [java] DEBUG [HttpProcessor[8080][0]]
[org.apache.webapp.actions.LoginServlet] LoginServlet.init(130) | Use
SSL for login? false
     [java] DEBUG [HttpProcessor[8080][0]]
[org.apache.webapp.actions.LoginServlet] LoginServlet.init(131) |
Programmatic encryption of password? False

.

    [junit] INFO [main] [httpclient.wire] Log4JCategoryLog.info(88) | <<
"<webresult><exception classname="javax.servlet
.ServletException"><message><![CDATA[No 'authURL' Context Parameter
supplied in web.xml]]></message><stacktrace><![CDATA
[javax.servlet.ServletException: No 'authURL' Context Parameter supplied
in web.xml

Any ideas are appreciated.  It's late and hopefully I'm just overlooking
something.

Thanks,

Matt
