Hi everybody!

I'm trying to test my Apache MINA filter with JUnit and EasyMock. Can
you help me?
XMLMappingFilter() should convert XML String to Object.

I defined instance of tested class and 3 mocks:

    @Before
    public void setUp() throws Exception {
        instance = new XMLMappingFilter();

        nextFilterMock = createMock(NextFilter.class);
        sessionMock = createMock(IoSession.class);
        messageMock = createMock(String.class);
        instance.messageReceived(nextFilterMock, sessionMock,
messageMock);

    }

and try to test:

    @Test
    public void testMessageReceived() throws Exception {
        System.out.println("messageReceived");
        //2. record mock
        messageMock.toString();
        expectLastCall().andReturn("<message username=\"user@domain.com
\"><body>Wiadomo=C5=9B=C4=87!</body></message>");
        expect(sessionMock).
        //3. replay mocks
        replay(nextFilterMock);
        replay(sessionMock);
        replay(messageMock);
        //4.tes
        instance.messageReceived(nextFilterMock, sessionMock,
messageMock);
        //.....
    }
instance.messageReceived() should call
nextFilterMock.messageReceived() with changed new parameters.
My question is: How to check with what parameters this method is
called?
In other words: How to verify, did strings are correctly converting to
objects?
