Mockito when() 不区分子类

Question

我编写了一个使用 Mockito 1.9.5 的测试。我有一个HttpGet 和一个HttpPost 执行HttpClient，我正在测试以验证每个响应是否以输入流的形式返回预期结果。

问题是在使用 Mockito.when(mockedClient.execute(any(HttpPost.class))).thenReturn(postResponse) 和 Mockito.when(mockedClient.execute(any(HttpGet.class))).thenReturn(getResponse)，其中响应是不同的对象，mockedClient.execute() 总是返回 getResponse。

我写的测试如下：

private InputStream       postContent;
private InputStream       getContent;
@Mock
private FilesHandler hand;
@Mock
private MockHttpClient    client;
private MockHttpEntity    postEntity;
private MockHttpEntity    getEntity;
private MockHttpResponse  postResponse;
private MockHttpResponse  getResponse;
private String imgQuery = "someQuery";
private ParametersHandler ph;
private FileHandlerImpl   fileHand;
private String            indexFolder = "src/test/resources/misc/";
private String            indexFile   = "index.csv";

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
    try {
        postContent = new FileInputStream(indexFolder + "testContent.txt");
        postEntity = new MockHttpEntity(postContent);
        postResponse = new MockHttpResponse(postEntity, new BasicStatusLine(new ProtocolVersion("http", 1, 1), 200, "postReasonPhrase"));
        getContent = new FileInputStream(indexFolder + "testContent.txt");
        getEntity = new MockHttpEntity(getContent);
        getResponse = new MockHttpResponse(getEntity, new BasicStatusLine(new ProtocolVersion("http", 1, 1), 200, "getReasonPhrase"));
        ph = new ParametersHandler();
        fileHand = new FileHandlerImpl(client, ph, indexFolder, indexFile);
    } catch (Exception e) {
        failTest(e);
    }
}
@Test
public void getFileWhenEverythingJustWorks() {

    try {
        Mockito.when(client.execute(Mockito.any(HttpPost.class))).thenReturn(postResponse);
        Mockito.when(client.execute(Mockito.any(HttpGet.class))).thenReturn(getResponse);
        fileHand.getFile(hand, imgQuery, ph, "I");
        Mockito.verify(hand).rebuildIndex(Mockito.any(String.class), Mockito.any(Map.class), Mockito.any(Map.class), hand);
    } catch (IOException e) {
        failTest(e);
    }
}

正在测试的方法的简化版本如下。

public void getFile(FilesHandler fileHandlerFl, String query, ParametersHandler ph, String type) {

        JsonFactory factory = new JsonFactory();
        HttpPost post = preparePost(query, factory);
        CloseableHttpResponse response = client.execute(post);

    String uri = "https://someuri.com" + "/File";
        HttpGet get = new HttpGet(uri);
        setParameters(get);
        response.close();
        response = client.execute(get);
}

一如既往，感谢您提供的任何帮助。

尽管在 Mockito 1.x、any(HttpGet.class) matches any value and not just any HttpGet 中用英语阅读时会意味着什么。该参数仅用于保存 Java 8 之前的强制转换。

来自Matchers.any(Class) documentation：

匹配任何对象，包括空值

此方法不对给定参数进行类型检查，它只是为了避免在代码中进行强制转换。但是，这可能会在未来的主要版本中发生变化（可能会添加类型检查）。

请改用 isA(HttpGet.class) 和 isA(HttpPost.class)，请参阅下面 Brice 关于 any(Class<?> clazz) 匹配器未来更改的评论。
