如何使用Mockito测试SOAP消息？

Question

我是Mockito的新手,我想我会尝试用它来测试一个SOAP Handler.然而,事实证明这比我预期/期望的要痛苦得多.

我希望验证我的处理程序能够在SOAPMessage的标头中提取messageID.但是,从处理程序,到达标题的唯一方法是通过context/message/part/envelope/header.使用Mockito我的解决方案是模拟我的SOAPMessage,意味着创建每个单独的对象,并对方法进行存根.

我只能想象有一种更容易/更清洁的方法来完成这个:

@RunWith(MockitoJUnitRunner.class)
public class UUIDHandlerTest {

    @Mock private SOAPMessage message;
    @Mock private SOAPEnvelope envelope;
    @Mock private SOAPHeader header;
    @Mock private SOAPPart part;

    @Mock
    private SOAPMessageContext context;

    @Before
    public void setup() throws SOAPException{
        when( context.getMessage()).thenReturn(message);
        when( message.getSOAPPart()).thenReturn(part);
        when( part.getEnvelope()).thenReturn(envelope);
        when( envelope.getHeader()).thenReturn(header);
    }


    @Test
    public void testHandleInboundMessage() {
        when( context.get(SOAPMessageContext.MESSAGE_OUTBOUND_PROPERTY)).thenReturn(false);

        when(header.getElementsByTagName(anyString())).thenAnswer(new Answer<NodeList>() {
            /* (non-Javadoc)
             * @see org.mockito.stubbing.Answer#answer(org.mockito.invocation.InvocationOnMock)
             */
            @Override
            public NodeList answer(InvocationOnMock invocation) throws Throwable {
                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                DocumentBuilder db = dbf.newDocumentBuilder();
                Document doc = db.parse(new ByteArrayInputStream(new String("<wsa:MessageID>messageId</wsa:MessageID>").getBytes()));

                // TODO Auto-generated method stub
                return doc.getElementsByTagName("wsa:MessageID");
            }

        });


        // call the test class
        new UUIDHandler().handleMessage(context);

        // check the MDC value
        assertEquals("messageId", MDC.get(LoggerConstants.DC_PROPERTY_MESSAGE_ID));
    }
}

就像我说的,它有效,但它看起来像一个非常丑陋/重量级的解决方案.

反正这样做更容易/更干净吗？

谢谢!

Answer 1

    SOAPMessageContext context = 
            mock(SOAPMessageContext.class, RETURNS_DEEP_STUBS);
    when(context.getMessage().getSOAPPart().getEnvelope().
            getHeader().getElementsByTagName(anyString())).
            then(...);

另请注意mockito文档中有关使用深度存根的注释。 http://docs.mockito.googlecode.com/hg/org/mockito/Mockito.html#RETURNS_DEEP_STUBS

注释风格：

    @Mock(answer = Answers.RETURNS_DEEP_STUBS) SOAPMessageContext context;
