Question

我实现了 REST Web服务，并希望使用jUnit测试来测试我的实现。

当我使用 REST 参考框架 Jersey 时，我想使用提供的测试框架 JerseyTest ，但我得到一些奇怪的行为：

如果我的资源创建了一个包含String的响应，那么每件事都可以正常工作（参见测试用例 responseCodeIs404IfGetForNotExistingGuiTag（））。一旦我的响应包含pojo，就会出现问题（请参阅测试用例 responseCodeIs200IfGetForExistingGuiTag（））。我没有收到预期的200响应代码，而是500'内部服务器错误'。如果我“手动”测试整个界面，那么每件事都可以。所以我假设我需要以某种方式配置测试框架，但我无法弄清楚如何。

我将this实施作为模板。

我使用Jersey 2.0（因为它目前在我的glassfish 4.0上运行（没有机会更新）），Mockito作为模拟框架，Jackson作为JSON框架。

我希望你们能帮助我。如果您需要更多信息，请告诉我。

GuiTagResource.java

@Path("/char")
public class GuiTagResource {

    private GuiTagRepository guiTagRepo;

    @Inject
    public void setGuiTagRepo(GuiTagRepository guiTagRepo) {
        this.guiTagRepo = guiTagRepo;
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{id}")
    public Response getGuiTagById(@PathParam("id") int guiTagNo) {

        Optional<GuiTag> guiTag = guiTagRepo.getCharGuiTagById(guiTagNo);

        Response response;

        if (!guiTag.isPresent()) {
            //This case works fine
            response = Response.status(404).entity("GuiTag with id " + Integer.toString(guiTagNo) + " was not found.")
                    .type(MediaType.APPLICATION_JSON).build();
        } else {
            //This case produces a 404 Error
            CharacteristicGuiTag guiTagTo = fromEntity((CharacteristicGuiTagEntity) guiTag.get());
            response = Response.status(200).entity(guiTagTo).build();
        }

        return response;
    }
}

GuiTagResourceTest.java

public class GuiTagResourceTest extends JerseyTest {
    @Mock
    private GuiTagRepository repoMock;

    @Override
    protected Application configure() {

        MockitoAnnotations.initMocks(this);

        enable(TestProperties.LOG_TRAFFIC);
        enable(TestProperties.DUMP_ENTITY);

        ResourceConfig config = new ResourceConfig(GuiTagResource.class);
        config.register(new InjectableProvider());

        return config;
    }

    @Test
    public void responseCodeIs404IfGetForNotExistingGuiTag() {

        when(repoMock.getCharGuiTagById(Mockito.anyInt())).thenReturn(absent());

        Response response = target("char/5").request().get();

        //Passes -> response code is 404
        assertThat(response.getStatus(), is(404));
    }

    @Test
    public void responseCodeIs200IfGetForExistingGuiTag() {

        Optional<GuiTag> compareTag = getGuiTagMock();
        CharacteristicGuiTag pojo = fromEntity((CharacteristicGuiTagEntity)     compareTag.get());

        when(repoMock.getCharGuiTagById(Mockito.anyInt())).thenReturn(compareTag);

        Response response = target("char/5").request().get();

        CharacteristicGuiTag responsePojo = response.readEntity(CharacteristicGuiTag.class);

        //Doesn't pass as response is 500?
        assertThat(response.getStatus(), is(200));
    }

    private Optional<GuiTag> getAbsentMock() {
        //returns a Optional.absent() to fake a failed db get.
    }

    private Optional<CharacteristicGuiTagEntity> getCharGuiTagMock() {
        //returns a guiTag
    }

    class InjectableProvider extends AbstractBinder implements Factory<GuiTagRepository> {

        @Override
        protected void configure() {
            bindFactory(this).to(GuiTagRepository.class).in(Singleton.class);
        }

        public GuiTagRepository provide() {
            return repoMock;
        }

        public void dispose(GuiTagRepository service) {
            repoMock = null;
        }
    }

}
