Junit test sample for REST API's using DropWizzard.

[Kuttaiah Robin]

Hello all,

Am looking for a sample to write junit test case for DropWizzard.

For Oracle Helidon/J4C  I have something like below;

public class ModelResourceTest extends org.glassfish.jersey.test.JerseyTest {


  @Override
  protected org.glassfish.jersey.test.spi.TestContainerFactory getTestContainerFactory() {
    return new  org.glassfish.jersey.test.inmemory.InMemoryTestContainerFactory();
  }


  @Override
  protected Application configure() {
    try {
      MockitoAnnotations.initMocks(this);
      MyMicroServiceClass microService = new MyMicroServiceClass();
      ResourceConfig rc = Whitebox.<ResourceConfig>invokeMethod(microService, "createBlankResourceConfig");
      rc.register(new AbstractBinder() {
        @Override
        protected void configure() {
          bind(m_MyContext).to(MyContext.class);
        }
      });
      //Registers all our REST resource in below.
      microService.customizeResourceConfig(rc);
      return rc;
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }
 
 
  @Test
  public void testListModelsDraft() throws Exception {
    ExecutionContextFactory factory = mock(ExecutionContextFactory.class);
    Whitebox.setInternalState(ExecutionContextFactory.class, "INSTANCE", factory);


    InsightDocumentStoreMetadataManager dsMetadataMrgMock = mock(InsightDocumentStoreMetadataManager.class);
    Whitebox.setInternalState(InsightDocumentStoreMetadataManager.class, "INSTANCE", dsMetadataMrgMock);

    ModelStatusDB modelStatusMockDB = mock(ModelStatusDB.class);
    Whitebox.setInternalState(ModelStatusDB.class, "INSTANCE", modelStatusMockDB);
    given(modelStatusMockDB.getModelStatus("OnlineShoppingApp","1.0")).willReturn(getModelStatus());

    given(dsMetadataMrgMock.getMetadata(draftPath)).willReturn(getSearchDocumentResponse(true));
    given(dsMetadataMrgMock.getDocument(draftPath+"OnlineShoppingApp/1.0/"+ProcMonMDSUtils.getBusinessContextFileName(), "1.0")).willReturn(getContextStream());
    given(dsMetadataMrgMock.getDocument(draftPath+"OnlineShoppingApp/1.0/"+ProcMonMDSUtils.getBusinessContextMappingFileName(), "1.0")).willReturn(getMappingStream());


    //call REST API
    Response response = target("/models").request().get(Response.class);
    System.out.println("Response testListModelsDraft->"+response);


    assertEquals(Response.Status.OK.getStatusCode(), response.getStatus());


    List<ModelInfo> results = response.readEntity(new GenericType<List<ModelInfo>>(){});


    assertEquals(1, results.size());
    ModelInfo modelInfo = results.get(0);
    assertNull( modelInfo.getState());
    assertEquals(modelInfo.getId(),"OnlineShoppingApp");
    assertNotNull(modelInfo.getDraft());
    assertNull(modelInfo.getCommitted());
  }  
}

Could you recommend on how this can be achieved for DropWizzard.  I would like to tweak little above existing test case and make it work.

thanks
