Unable to execute any StrutsTestCase using Struts2-Junit-Plugin, action method is null

Question

First of all sorry if I don't explain it clearly enough, I will try to do my best. Recently I switched from C/C# to Java, and I'm a bit overwhelmed.

I'm working on a project that is using Struts2+Hibernate (I'm not using Spring); the idea was to use the struts2-JUnit-plugin to test the actions.

I followed the strut2-junit-plugin tutorial without success and after a lot of research and trying all the possible solutions posted everywhere I couldn't find the good one.

The "issues" (because I'm not really sure whether this is an issue or not...) I have is that when I try to run a StrutsTestCase, during the setUp:

super.setUp();
initServletMockObjects();
setupBeforeInitDispatcher();
dispatcher = initDispatcher(dispatcherInitParams);
setupAfterInitDispatcher(dispatcher);

When calling dispatcher = initDispatcher(dispatcherInitParams), dispatcherInitParams is null and it throws the following stack trace:

After this, even that I got the error, I can continue testing, for instance, the following test:

@Test
public void testGetActionProxy() throws Exception {

    //set parameters before calling getActionProxy
    PasswordUpdate pu = new PasswordUpdate();
    pu.setCurrentPassword("current");
    pu.setNewPassword("new");
    pu.setNewPasswordConfirm("new");
    request.setParameter("passwordUpdate.currentPassword", pu.getCurrentPassword());
    request.setParameter("passwordUpdate.newPassword", pu.getNewPassword());
    request.setParameter("passwordUpdate.newPasswordConfirm", pu.getNewPasswordConfirm());

    ActionProxy proxy = getActionProxy("/UpdatePassword.action");
    assertNotNull(proxy);

    PasswordAction action = (PasswordAction) proxy.getAction();
    assertNotNull(action);

    String result = proxy.execute();
    assertEquals(Action.SUCCESS, result);
    assertNotNull(action.getPasswordUpdate());
    assertEquals("current", action.getPasswordUpdate().getCurrentPassword());
    assertEquals("new", action.getPasswordUpdate().getNewPassword());
    assertEquals("new", action.getPasswordUpdate().getNewPasswordConfirm());

}

The second issue is that it doesn't seem to find the action when calling:

ActionProxy proxy = getActionProxy("/UpdatePassword.action");

It's throwing an exception inside getActionProxy:

protected ActionProxy getActionProxy(String uri) {
        request.setRequestURI(uri);
        ActionMapping mapping = getActionMapping(request);
        String namespace = mapping.getNamespace();
        String name = mapping.getName();
        String method = mapping.getMethod();

        Configuration config = configurationManager.getConfiguration();
        ActionProxy proxy = config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy(
                namespace, name, method, new HashMap<String, Object>(), true, false);

        initActionContext(proxy.getInvocation().getInvocationContext());

        // this is normally done in onSetUp(), but we are using Struts internal
        // objects (proxy and action invocation)
        // so we have to hack around so it works
        ServletActionContext.setServletContext(servletContext);
        ServletActionContext.setRequest(request);
        ServletActionContext.setResponse(response);

        return proxy;
    }

At this point String method is null and the following call is throwing an exception:

ActionProxy proxy = config.getContainer().getInstance(ActionProxyFactory.class).createActionProxy( namespace, name, method, new HashMap(), true, false);

Any idea before I give up?

Thank you!

In case someone else ends up in this post with the same issue

You can fix this by excluding from your configuration struts2-cdi-plugin
