本篇文章翻译自Espresso & UIAutomator - the perfect tandem

Espresso是个功能强大、执行速度很快的Android自动化测试框架，但是它有一个重要的局限-你只可以在被测App的Context中操作。

意味着下列App自动化测试需求无法实现：

• 应用的推送消息
• 同步联系人
• 从另一个应用程序进入被测App

因为你要处理移动设备的其他应用程序，比如通知栏、联系人等。

事实上，UIAutomator 2.0发布后可以实现上述功能。如Android Developers blog post所说“最重要的是，UIAutomator现在已经基于Android Instrumentation...”，因此，使用Instrumentation test runner既可以运行UIAutomator，也可以运行Espresso。

另外，我们可以将UIAutomator和Espresso测试结合起来，可以更加得心应手的处理被测应用和电话之间的交互。

下面的例子，我将解释如何使用这种方法来自动化测试App的联系人同步功能。

import android.support.test.InstrumentationRegistry;import android.support.test.rule.ActivityTestRule;import android.support.test.runner.AndroidJUnit4;import android.support.test.uiautomator.UiDevice;import android.support.test.uiautomator.UiObject;import android.support.test.uiautomator.UiSelector;@RunWith(AndroidJUnit4.class)public class TestContactsSync {    @Rule    public ActivityTestRule mActivityRule = new ActivityTestRule(LoginActivity.class);    UiDevice mDevice;    String PEOPLE_APP = "People";    String MY_APP = "XING";    String userContactName = "Android Tester";    @Before    public void setUp() throws Exception{        super.setUp();        mDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());    }    @Test    public void testContactsSync() throws Exception {        // Espresso code: login the user, navigate to contact sync and enable clicking on toggle        logInUser();        onView(withText(R.string.sync_button)).perform(click());        onView(withId(R.id.contacts_sync_enable_toggle)).perform(click());        // UIAutomator code: navigate to People app         mDevice.pressHome();        UiObject conutactsApp = mDevice.findObject(new UiSelector().text(PEOPLE_APP));        conutactsApp.clickAndWaitForNewWindow();        // UIAutomator code: check that contact is present in it after sync was triggered            UiObject contactName = mDevice.findObject(new UiSelector().text(userContactName));        assertTrue(contactName.exists());        // UIAutomator code: navigate back to my app under testm        Device.pressHome();        UiObject myApp = mDevice.findObject(new UiSelector().text(MY_APP));        myApp.clickAndWaitForNewWindow();        // Espresso code: turn off contact sync and logout        onView(withId(R.id.contacts_sync_enable_toggle)).perform(click());        onView(withId(R.id.logout)).perform(click());    }    @After    public void tearDown() throws Exception {        super.tearDown();    }}

是不是很完美？UIAutomator需要Android 4.3（API Level 18）及更高版本。稍微修改下build.gradle文件即可-添加productFlavors和声明uiautomator依赖。

productFlavors {    // The actual application flavor     production {        minSdkVersion 14    }    // Test application flavor for uiautomatior tests    test {        minSdkVersion 18    }}dependencies {    // Instrumentation tests    androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.1'    androidTestCompile 'com.android.support.test:rules:0.2'    // Set this dependency to build and run UI Automator tests    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.0.0'}

祝你好运:)
