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");
}
};
}

}

Hi

I think maybe you need to use the mockito mocked instance here instead
of creating a new instance yourself

context.bind("messageInformationService", new
MessageInformationServiceImpl());

Hi Damien,

I don't know exactly about Mockito's Spy capabilities, but perhaps you'd try it with the annotation @RunWith(MockitoJUnitRunner.class) at your class.

Claus: I removed that lines, cause you are right, there is no need to
create bean that will be mocked
Christian: I added it, and still the same issue..

Hi Damien,

Yeah if you use that @Spy annotation then you may need some kind of
mockitio runner to kick-in and initialize that field based on that
@Spy annotation.
Then you may look at not extending CamelTestSupport and use those
jrunit runner annotaitons and whatelse you need to set on top of the
class.

Try to find som mockit @Spy examples with junit and then go from
there. Or find another way to do the @Spy stuff with maybe the mockit
java api to set it up yourself.
