test unit a processor with an embedded autowired bean

[Damien Nicolas]

 Hello,

I would like to unit test a processor containing a service as an autowired
bean (*messageInformationService*). I would like to mock this bean to make
it return the data I want, but when I do that with Mockito, my service is
null.
*Here is my test class:*

public class GenerateCertificateTest extends CamelTestSupport {

    @Spy
    private MessageInformationService messageInformationService;

    @Before
    public void setUp() throws Exception {
        super.setUp();

        messageInformationService =
Mockito.mock(MessageInformationServiceImpl.class);
        Mockito.doReturn(new
MessageInformation()).when(messageInformationService).getMessageInformation("1",
"2");
    }

    @Test
    public void test1() throws Exception {
        ObjectMapper mapper = new ObjectMapper();
        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

        Chip chipIn = new Chip();
        Header header = new Header();
        header.setId("1234567890");
        chipIn.setHeader(header);
        Card card = new Card();
        card.setNumber1("1");
        card.setNNumber2("2");
        chipIn.setCard(card);
        Map<String, Object> headers = new HashMap<>();
        headers.put("workflow", "test1#test2");

        template.sendBodyAndHeaders("direct:start",
mapper.writeValueAsString(chipIn), headers);

        MockEndpoint mock = getMockEndpoint("mock:result");
        mock.expectedMessageCount(1);
        mock.message(0).body().isInstanceOf(chipIn.getClass());

        Message m = mock.getExchanges().get(0).getIn();

        Chip chipResult = mapper.readValue(m.getBody(String.class),
Chip.class);
        chipResult.setProductionStep(ProductionStep.GENERATE_CERTIFICATE);

        Assert.assertEquals("test2", m.getHeader("workflow"));
        Assert.assertEquals(chipResult.getProductionStep(),
ProductionStep.GENERATE_CERTIFICATE);
    }

    @Override
    protected JndiContext createJndiContext() throws Exception {
        JndiContext context = new JndiContext();
        context.bind("messageInformationService", new
MessageInformationServiceImpl());
        return context;
    }


    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {
        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:start").process(new
GenerateCertificate()).to("mock:result");
            }
        };
    }

}
