Getting “At least one JPA metamodel must be present” with @WebMvcTest

Question

I\'m fairly new to Spring, trying to do some basic integration tests for a @Controller.

@RunWith(SpringRunner.class)
@WebMvcTest(DemoController.clas         


        

Answer 1

Alternatively, you can define a custom configuration class inside your test case, including only the controller (plus its dependencies), to force Spring to use this context.
Please note, you'll still have access to MockMvc and other goodness in your test case, if it's WebMvcTest annotated.

@RunWith(SpringRunner.class)
@WebMvcTest(DemoController.class)
public class DemoControllerIntegrationTests {
    @Autowired
    private MockMvc mvc;

    @MockBean
    private DemoService demoService;

    @Test
    public void index_shouldBeSuccessful() throws Exception {
        mvc.perform(get("/home").accept(MediaType.TEXT_HTML)).andExpect(status().isOk());
    }

    @Configuration
    @ComponentScan(basePackageClasses = { DemoController.class })
    public static class TestConf {}
