jersey客户端的java测试用例失败

Question

我有一个像这样的客户

 public ClientResponse getCall(String apiName){
         restClient = getRestClient();
        WebResource webResource = restClient
                .resource(Constants.FUELWISE_END_POINT+apiName);
         return  webResource.accept(Constants.APPLICATION_JSON)
                 .header(Constants.AUTHORIZATION_HEADER, Constants.AUTHORIZATION_VALUE).get(ClientResponse.class);
    }

并具有mockito测试用例行，如：

   @Test
    public void getCallTest() {

        when(restClient.resource(any(String.class))).thenReturn(webResource);

        when(webResource.accept(any(String.class)).header(any(String.class), any(Object.class))
                .get(eq(ClientResponse.class))).thenReturn(clientResponse);

        restUtilityTest.getCall("messages");
    }

已扩展测试java类以返回restClient mock而不是Client。从方法getRestClient（）创建（）

使用@Mock使用注释进行模拟

堆栈跟踪错误：

This message may appear after an NullPointerException if the last matcher is returning an object 
like any() but the stubbed method signature expect a primitive argument, in this case,
use primitive alternatives.

在测试用例文件中完成模拟：

    @InjectMocks
    private RestUtilityTest restUtilityTest;

    @Mock
    private Client restClient;

    @Mock
    private WebResource webResource;

    @Mock(name = "response")
    private ClientResponse clientResponse;

Answer 1

确保被测对象及其依赖关系安排正确

@Test
public void getCallTest() {
    //Arrange    
    ClientResponse clientResponse = mock(ClientResponse.class);

    WebResource webResource = mock(WebResource.class);    
    when(webResource
            .accept(any(String.class))
            .header(any(String.class), any(String.class))
            .get(eq(ClientResponse.class))
        )
        .thenReturn(clientResponse);

    Client restClient = mock(Client.class);
    when(restClient.resource(any(String.class))).thenReturn(webResource);

    RestUtilityTest restUtilityTest = new RestUtilityTest(restClient);

    //Act
    ClientResponse response = restUtilityTest.getCall("messages");

    //Assert
    //...
}

注意使用any(String.class)和eq()来匹配参数

上面假设模拟的web资源被正确地注入到测试的主题类中
