我使用 WireMock 进行的仪器化测试（在文件夹 "androidTest" 中）：
public class WireMockApplicationTestCase2 {
@Rule
public ActivityTestRule<MainActivity> activityRule = new ActivityTestRule<>(MainActivity.class);
private Context androidTestContext;
private Context applicationContext;
@Before
public void setUp() throws Exception {
this.androidTestContext = InstrumentationRegistry.getContext();
this.applicationContext = InstrumentationRegistry.getTargetContext().getApplicationContext();
wireMockServer = new WireMockServer(8089);
wireMockServer.start();
}
@Test
public void testWiremockPlusOkHttp() throws IOException {
String serviceEndpoint = "http://127.0.0.1:" + 8089;
OkHttpClient okHttpClient = // some code fot http client;
String uri = "/hello-world";
Request request = new Request.Builder()
.url(serviceEndpoint + uri)
.build();
Response response = okHttpClient.newCall(request).execute();
String responseBodyStr = response.body().string();
assertEquals("hello world", responseBodyStr);
}
}
但是当我开始这个测试时（在 Android 7.0 上）我得到错误：

在您的 gradle 文件中，您可能需要包含 android 版本的 apache httpclient：
androidTestCompile group: 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
我找到了问题的解决方案：
1.If 你使用 Android 5.0-（例如 Android 4.3）然后你 必须 使用 Wiremock 版本 2.0 .8-beta
androidTestCompile 'com.github.tomakehurst:wiremock:2.0.8-beta'
2.If 你使用 Android 5.0+ 你可以使用任何 Wiremock 版本（例如 2.5.0）
androidTestCompile 'com.github.tomakehurst:wiremock:2.6.0'
P.S。也许这是一个 Multidex 问题。
