使用MockWebServer进行网络呼叫的测试方法

Question

iam试图编写测试用例来测试连接到Internet的功能并使用FastAndroidNetworking lib进行调用，但这给了我错误 请任何人能帮助解决这个问题

junit.framework.ComparisonFailure： 预期的：{“响应”：“这是一个获取请求”} 实际：null

@PowerMockIgnore("javax.net.ssl.*")
public class HttpServiceMethods {

    private final Map<String, String> requestHeaders = new HashMap<>();
    private final String expectedResponse = "{\"response\":\"This is a get request\"}";
    MockWebServer server;

    @Before
    public void setup() throws IOException {
        // instance for every unit test.
        if (server == null) {
            server = new MockWebServer();
        }
        // Schedule some responses.
        MockResponse mockResponse = new MockResponse();
        mockResponse.setBody(expectedResponse);
        mockResponse.setResponseCode(200);
        mockResponse.throttleBody(1024, 1, TimeUnit.SECONDS);
        server.enqueue(mockResponse);

       // Start the server.
        server.start();


    }

    @Test
    public void getRequest() throws IOException {


        // reference
        final AtomicReference<String> responseRef = new AtomicReference<>();

        final CountDownLatch latch = new CountDownLatch(1);

        AndroidNetworking.get(server.url("/").toString())
                .addHeaders(requestHeaders)
                .build()
                .getAsOkHttpResponseAndString(new OkHttpResponseAndStringRequestListener() {
                    @Override
                    public void onResponse(Response okHttpResponse, String response) {
                        if (okHttpResponse.isSuccessful()) {

                            responseRef.set(response);
                            latch.countDown();
                        }
                    }

                    @Override
                    public void onError(ANError anError) {
                        assertTrue(false);
                    }
                });

        // assertTrue(latch.await(2, SECONDS));
        //Assert.assertNotNull(responseRef.get());
        assertEquals(expectedResponse, responseRef.get());
    }

    @After
    public void closeServer() throws Exception {
        server.shutdown();
    }
}

这是我的实际方法

public void getRequest(String requestUrl, Map<String, String> headers, CallListener callListener) {
        System.out.println("Inside get.");
        AndroidNetworking.get(requestUrl)
                .addHeaders(headers)
                .setPriority(Priority.LOW)
                .build()
                .getAsOkHttpResponseAndString(new OkHttpResponseAndStringRequestListener() {
                    @Override
                    public void onResponse(Response okHttpResponse, String response) {
                        if (okHttpResponse != null && okHttpResponse.isSuccessful()) {
                            System.out.println("success");
                            Log.d(TAG, "Headers :" + okHttpResponse.headers());
                            callListener.onSuccess(response);
                        }

                    }

                    @Override
                    public void onError(ANError error) {
                        System.out.println("success");
                        if (error.getErrorCode() != 0 && error != null) {
                            Log.d(TAG, "onError errorCode : " + error.getErrorCode());
                            Log.d(TAG, "onError errorBody : " + error.getErrorBody());
                            Log.d(TAG, "onError errorDetail : " + error.getErrorDetail());
                            String fullError = error.getErrorCode() + error.getErrorBody() + error.getErrorDetail();
                            callListener.onFailure(fullError);

                        }

                    }
                });
    }
