我正在使用OkHttp MockWebServer来模拟我的服务器响应以进行单元测试。
它适用于第一次测试，但在第二次测试中，我的客户失败了：
无法连接到 localhost/0:0:0:0:0:0:0:1:63631
即使第二次测试与第一次完全相同，也会发生这种情况。
这就是我正在做的事情：
@RunWith(RobolectricTestRunner.class)
@Config(shadows = MyClassTest.MyNetworkSecurityPolicy.class,
manifest = "src/main/AndroidManifest.xml",
constants = BuildConfig.class,
sdk = 16)
public class MyClassTest {
private MockWebServer mockServer;
private MyServerApi serverApi;
@Before
public void setUp() throws Exception {
System.out.println("\ntest start");
this.mockServer = new MockWebServer();
this.mockServer.start();
this.serverApi = new MyServerApi(this.mockServer.url("/").toString());
}
@Test
public void testOne() throws Exception {
final String responseBody = // read response from file
this.mockServer.enqueue(new MockResponse().setResponseCode(200).setBody(responseBody));
final Waiter waiter = new Waiter();
this.serverApi.getData("some_id", new Callback<MyResponseData> {
@Override
public void onResponse(final Call<MyResponseData> call, final Response<MyResponseData> response) {
waiter.assertEquals("some_value", response.body().getValue());
waiter.resume();
}
@Override
public void onFailure(final Call<T> call, final Throwable error) {
waiter.fail(error);
}
});
waiter.await();
final RecordedRequest recordedRequest = this.mockServer.takeRequest();
assertEquals("GET", recordedRequest.getMethod());
}
@Test
public void testTwo() throws Exception {
final String responseBody = // read response from file
this.mockServer.enqueue(new MockResponse().setResponseCode(200).setBody(responseBody));
final Waiter waiter = new Waiter();
this.serverApi.getData("some_id", new Callback<MyResponseData> {
@Override
public void onResponse(final Call<MyResponseData> call, final Response<MyResponseData> response) {
waiter.assertEquals("some_value", response.body().getValue());
waiter.resume();
}
@Override
public void onFailure(final Call<T> call, final Throwable error) {
waiter.fail(error);
}
});
waiter.await();
final RecordedRequest recordedRequest = this.mockServer.takeRequest();
assertEquals("GET", recordedRequest.getMethod());
}
@After
public void tearDown() throws Exception {
System.out.println("test end\n");
this.mockServer.shutdown();
}
@Implements(NetworkSecurityPolicy.class)
public static class MyNetworkSecurityPolicy {
@Implementation
public static NetworkSecurityPolicy getInstance() {
try {
Class<?> shadow = MyNetworkSecurityPolicy.class.forName("android.security.NetworkSecurityPolicy");
return (NetworkSecurityPolicy) shadow.newInstance();
} catch (Exception e) {
throw new AssertionError();
}
}
@Implementation
public boolean isCleartextTrafficPermitted() {
return true;
}
}
}
第一个测试按原样通过，但第二个测试失败并显示我上面写的消息。
控制台中的输出是：
test start
okhttp3.mockwebserver.MockWebServer$3 execute
INFO: MockWebServer[63631] starting to accept connections

（Waiter对象来自concurrentunit lib）
知道为什么会这样吗？
