Testing Listeners

What is the recommended way to test Listeners with Cactus.  I have a
StartupListener ...

public class StartupListener implements ServletContextListener

... That talks to a database and reads a number of properties files -
and stuffs objects into the servlet context.  I basically just need to
verify that the variables get set correctly.

Thanks,

Matt

I've never used ServletContextListener but I've had a quick look and it
looks easy to unit test. Let's take an example:

public class MyListener implements ServletContextListener
{
    public void contextDestroyed(ServletContextEvent sce)
    {
      [...]
    }
    public void contextInitialized(ServletContextEvent sce)
    {
      [...]
    }
}

Here's the test:

public class MyListenerTest extends ServletTestCase
{
    public void testXXX()
    {
        // setup
        ServletContextEvent sce = 
            new ServletContextEvent(config.getServletContext());
        MyListener listener = new MyListener();
        
        // test
        listener.contextInitialized(sce);

        // asserts
   }
}

Now, what I don't know is whether you need the ServletContext in a given
state or not?

Is that the kind of test you want?
