@DataJpaTest does not work with wicket-spring-boot-starter

[ursjoss]

Hi Marc

I am experimenting with the new test features of spring-boot-1.4 in a JPA project. If I extend my application class from either WicketBootStandardWebApplication or WicketBootSecuredWebApplication, a working JPA integration test using the @DataJpaTest fails with the following exception:

[...]Error creating bean with name 'demoApplication': Unsatisfied dependency expressed through field 'generalSettingsProperties': No qualifying bean of type [com.giffing.wicket.spring.boot.starter.configuration.extensions.core.settings.general.GeneralSettingsProperties] found for dependency[...]

Note that the test is supposed to test the JPA layer in isolation, trying not to load regular @Components or anything from the Web layer into the application context.

I have created a relatively minimal example to illustrate the case: Example project on github The CustomerRepositoryTest fails with the given configuration. You can see it pass if you modify the DemoApplication class to not extend WicketBootStandardWebApplication.

Thanks upfront for checking this out. Thanks and cheers Urs

[MarcGiffing]

It seems that even with the @DataJpaTest annotation he is using the DemoApplication as the entry point. Cause of the interitence he creates the WicketBootStandardWebApplication bean and can't find the GeneralSettingsProperties bean.

Workaround: You can move the WicketBootStandardWebApplication in a separated class. So that the WicketBootStandardWebApplication is not created at all.

I will think of an alternative aproach...

[MarcGiffing]

I don't see any other alternative. Did you tried out my proposal?

Hi Marc

I managed to get the test running while still extending WicketBootStandardApplication. I simply provided the two missing dependencies by mocking them using @MockBean, i.e.

@RunWith(SpringRunner.class)
@DataJpaTest
public class CustomerRepositoryTest { 

    @Autowired
    private CustomerRepository repo;

    @MockBean
    private GeneralSettingsProperties generalSettingsProperties;
    @MockBean
    private WicketClassCandidatesHolder classCandidates;

    @Test
    public void test() {
        assertThat(repo.count()).isEqualTo(0);
    }
}
