Spring integrationflow test

Question

I am trying to test

 @Bean
public IntegrationFlow integrationFlow(JobLaunchingGateway jobLaunchingGateway) {
    return IntegrationFlows.from(inventoryImportInboundChannelAdapter,
            p -> p.poller(Pollers.fixedRate(inventoryImportJobProperties.getPollingFrequency()))).
            handle(fileMessageToPath()).
            handle(fileMessageToJobRequest()).
            handle(jobLaunchingGateway).
            log(LoggingHandler.Level.INFO, "headers.id + ': ' + payload").
            get();
}

Inventory import channel adapter is s3 adapter, i dont want to connect to S3 for component test. I tried using MockIntegrationContext and it did not work . Please advise

@RunWith(SpringRunner.class)
   @SpringBootTest(classes = {ImportInventoryJobIntegrationFlow.class})
   @SpringIntegrationTest
   public class ImportInventoryJobIntegrationFlowTest {

    @MockBean
    private MessageSource<?> inventoryImportInboundChannelAdapter;
    @MockBean
    private Job inventoryImportJob;
    @MockBean
    private JobRepository jobrepository;
    @MockBean
    private InventoryImportJobProperties inventoryImportJobProperties;


    @Autowired
    private MockIntegrationContext mockIntegrationContext;


    @Test
    public void testChannelAdapter(){
        File importFile = Mockito.mock(File.class);
        BDDMockito.given(importFile.getParent()).willReturn("test.import");
        System.out.println(mockIntegrationContext);
        this.mockIntegrationContext.substituteMessageSourceFor("inventoryImportInboundChannelAdapter",
                MockIntegration.mockMessageSource(importFile));

    }
}

Error getting is: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'inventoryImportInboundChannelAdapter' available

Please, refer to the mockIntegrationContext.substituteMessageSourceFor() JavaDocs:

/**
 * Replace the real {@link MessageSource} in the {@link SourcePollingChannelAdapter} bean
 * with provided {@link MessageSource} instance.
 * Can be a mock object.
 * @param pollingAdapterId the endpoint bean name
 * @param mockMessageSource the {@link MessageSource} to replace in the endpoint bean
 * @see org.springframework.integration.test.mock.MockIntegration#mockMessageSource
 */
public void substituteMessageSourceFor(String pollingAdapterId, MessageSource<?> mockMessageSource) {

The key word there is SourcePollingChannelAdapter. This bean is a result of your

IntegrationFlows.from(inventoryImportInboundChannelAdapter,
        p -> p.poller(Pollers.fixedRate(inventoryImportJobProperties.getPollingFrequency())))

Unfortunately you don't specify here that inventoryImportInboundChannelAdapter, so its target name is generated.

Consider to add .id("inventoryImportInboundChannelAdapter") before or after poller() definition for that endpoint.

UPDATE

We have a test configuration like this:

    @Bean
    public IntegrationFlow myFlow() {
        return IntegrationFlows
                .from(() -> new GenericMessage<>("myData"),
                        e -> e.id("mySourceEndpoint"))
                .<String, String>transform(String::toUpperCase)
                .channel(results())
                .get();
    }

Pay attention to the e.id("mySourceEndpoint") . And then in the test we do like this:

this.mockIntegrationContext.substituteMessageSourceFor("mySourceEndpoint",
            MockIntegration.mockMessageSource("foo", "bar", "baz"));
