我使用了库Robolectric另一个可能的框架。Android的Http客户端http://loopj.com/android-async-http/
static AsyncHttpClient client = new AsyncHttpClient();
public static void getData (final ServerCallback callback) {
client.get("http://httpbin.org/get", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
callback.onSuccess(statusCode, new String(responseBody));
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
callback.onFailure(statusCode, new String(responseBody));
}
});
}
测试类别：
@RunWith(RobolectricTestRunner.class)
public class ApiTest{
@Test
public void testgetData () {
}
}
接口
public interface ServerCallback {
// Api detect connection
void onSuccess(int statusCode, String response);
void onFailure(int statusCode, String response);
}
小说，
我将提供一个一般性的答案，以使您朝正确的方向前进。我测试HTTP请求的首选方法是使用方形okhttp mockwebserver。如果您对项目的单元测试有疑问，请复习一下。
在您的特定情况下，有几件事要解决：
因此，按照您的示例，让我们如下设置测试客户端：
public class TestHttpClient {
// package-local client that can be set in tests
static AsyncHttpClient client = new AsyncHttpClient();
// package-local baseUrl that can be set in tests
static String baseUrl = "http://pastbin.org/";
public static void getData(final ServerCallback callback) {
String url = baseUrl + "get";
client.get(url, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
callback.onSuccess(statusCode, new String(responseBody));
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
callback.onFailure(statusCode, new String(responseBody));
}
});
}
}
要测试TestHttpClient，请使用MockWebServer来启动服务器进行测试，并设置客户端向服务器发出请求：
@RunWith(RobolectricTestRunner.class)
@Config(manifest = Config.NONE, sdk = Build.VERSION_CODES.LOLLIPOP)
public class TestHttpRequestTest {
@Rule
public MockWebServer mockWebServer = new MockWebServer();
@Test
public void getData_onSuccess_doesSomething() throws InterruptedException {
// Here we are creating a mock ServerCallback. We will use
// this mock object to verify the callback is invoked
ServerCallback callback = mock(ServerCallback.class);
// To test the client, we need to send a request to the mock mockWebServer.
// The MockWebServer spins up an actual backend to handle calls. You MUST
// setup the client to use the base Url of the mockWebServer instead of
// the actual url e.g.: http://httpbin.org.
TestHttpClient.baseUrl = mockWebServer.url("/").toString();
// For testing, use a synchronous client so that we can get the response before
// the test completes.
TestHttpClient.client = new SyncHttpClient();
// Set up the mockWebServer to return a MockResponse with
// some data in the body. This data can be whatever you want... json, xml, etc.
// The default response code is 200.
mockWebServer.enqueue(new MockResponse().setBody("success"));
// To simulate an error
// mockWebServer.enqueue(new MockResponse().setResponseCode(500).setBody("error"));
TestHttpClient.getData(callback); // calling the method under test
verify(callback).onSuccess(200, "success"); // using verify of mockito
}
}
笔记：
async http client库需要一些android系统组件才能正常工作，因此您必须使用@RunWith(...)注释MockWebServer需要将@Config(sdk = 21)sdk设置为v21或更高版本才能与Robolectric一起使用。要在您的项目中包含模拟网络服务器和模拟人，请将以下内容添加到build.gradle
dependencies {
testCompile 'com.squareup.okhttp3:mockwebserver:3.2.0'
testCompile 'org.mockito:mockito-core:1.10.19'
}
测试愉快！！！
