第一次调用 Mockito 后身体反应为空

Question

我使用

Mockito

在我的应用程序中模拟一个

OkHttp

类。第一次模拟效果很好，我得到

"foo"

作为身体的回应，但第二次是空的。我试着调试它，看起来模拟正在工作，我不知道为什么它不能用于第二次调用。

我的测试：

@Test
void get500() throws IOException {
    String responseMessage = "foo";
    int responseCode = 500;

    final OkHttpClient okHttpClient = mock(OkHttpClient.class);
    final Call remoteCall = mock(Call.class);
    final Response responseBuilder = new Response.Builder()
            .request(new Request.Builder().url(url).build())
            .protocol(Protocol.HTTP_1_1)
            .code(responseCode).message("").body(
                    ResponseBody.create(
                            responseMessage,
                            MediaType.parse("application/json")
                    ))
            .build();

    when(remoteCall.execute()).thenReturn(responseBuilder);
    when(okHttpClient.newCall(any())).thenReturn(remoteCall);
    
    MyHttp myHttp = new MyHttp(okHttpClient);
    ResponseServer response = myHttp.get("http://url.com");
    Assertions.assertEquals(response.getBody(), responseMessage);
}

这是

MyHttp

课：

public class MyHttp {
    protected final OkHttpClient client;
    
    public MyHttp(OkHttpClient client) {
        this.client = client;
    }
    
    public ResponseServer get(String url) throws IOException {
        Request request = new Request.Builder()
                .url(url)
                .get()
                .build();
        
        Response response = client.newCall(request).execute();
        String responseBody = Objects.requireNonNull(response.body()).string();
        Assertions.assertEquals(response.getBody(), "foo");

        Response response2 = client.newCall(request).execute();
        String responseBody2 = Objects.requireNonNull(response2.body()).string();
        Assertions.assertEquals(response2.getBody(), "foo");  // response is empty
    }
}

编辑：

如下所示的模拟响应但没有用：

Response mockResponse = mock(Response.class);
when(mockResponse.request()).thenReturn(new Request.Builder().url(url).build());
when(mockResponse.protocol()).thenReturn(Protocol.HTTP_1_1);
when(mockResponse.code()).thenReturn(responseCode);
when(mockResponse.message()).thenReturn("");
when(mockResponse.body()).thenReturn(
        ResponseBody.create(
                responseMessage,
                MediaType.parse("application/json")
        ));
