Espresso - 检查使用按下按钮的意图打开了哪个 Activity？

Question

是否可以跟踪按下某个按钮后打开了哪个Activity？
我有一个测试，当单击/按下按钮时，它向服务器发送请求。在发送请求之前，它会打开一个 Activity。 为了验证测试是否成功执行，我需要检查打开的是什么Activity。

我的测试示例：

检查在 Espresso 中打开了哪个 Intent ---

 private void startTest() {
    recreateAuthData(InstrumentationRegistry.getTargetContext(), "d78269d9-9e00-4b8d-9242-815204b0a2f6", "3f32da21-914d-4adc-b6a1-891b842a2972");

    InstrumentationRegistry.getTargetContext().getSharedPreferences(ActivitySplashScreen.class.getSimpleName(),
            Context.MODE_PRIVATE).edit().putInt(ActivitySplashScreen.PROPERTY_APP_VERSION, ActivitySplashScreen.getAppVersion(InstrumentationRegistry.getTargetContext())).commit();
    InstrumentationRegistry.getTargetContext().getSharedPreferences(ActivitySplashScreen.class.getSimpleName(),
            Context.MODE_PRIVATE).edit().putString(ActivitySplashScreen.PROPERTY_REG_ID, "testKey").commit();

    mActivityRule.launchActivity(setIntent());
    // inputPinCode("2794");
}

@Test
public void testIdent() {
    startTest();
    onView(withText("ПРО")).perform(click());
    putDelay(500);
    onView(withId(R.id.get_pro)).perform(click());
    onView(withText("Авторизация по паспортным данным")).perform(click());
    putDelay(500);
    closeSoftKeyboard();
    onView(withId(R.id.btn_goto_passport)).perform(click());
    onView(withHint("Серия и номер паспорта")).perform(replaceText("9894657891"));
    onView(withHint("Дата выдачи паспорта")).perform(replaceText("17032014"));
    onView(withHint("Дата рождения")).perform(replaceText("31091994"));
    onView(withHint("СНИЛС")).perform(replaceText("54665285919"));
    putDelay(500);
    Log.d("TestWidget", hasComponent(hasShortClassName("ActivityMain")).toString());
    onView(withId(R.id.btn_next)).perform(click());
    // some code which check which activity is display now
    putDelay(500);

}

Whether it is possible to trace which the Activity opened after pressing the button?

检查 espresso-intents 图书馆：

配置

将这些行添加到您的 app/build.gradle 中：

androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.5'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.2'

NOTICE: espresso-intents won't run without espresso-core, runner or rules libs.

您可能还需要将 ActivityTestRule<> 更改为 IntentsTestRule，如下所述：

IntentsTestRule

Use IntentsTestRule instead of ActivityTestRule when using Espresso-Intents. IntentsTestRule makes it easy to use Espresso-Intents APIs in functional UI tests. This class is an extension of ActivityTestRule, which initializes Espresso-Intents before each test annotated with @Test and releases Espresso-Intents after each test run. The activity will be terminated after each test and this rule can be used in the same way as ActivityTestRule.

示例代码（点击按钮启动新的 activity）

这是使用 espresso-intents 解决类似问题的解决方案：

An example test with intent stubbing:

@Test
 public void testActivityResultIsHandledProperly() {
   // Build a result to return when a particular activity is launched.
   Intent resultData = new Intent();
   String phoneNumber = "123-345-6789";
   resultData.putExtra("phone", phoneNumber);
   ActivityResult result = new ActivityResult(Activity.RESULT_OK, resultData);

   // Set up result stubbing when an intent sent to "contacts" is seen.
   intending(toPackage("com.android.contacts")).respondWith(result));

   // User action that results in "contacts" activity being launched.
   // Launching activity expects phoneNumber to be returned and displays it on the screen.
   user.clickOnView(system.getView(R.id.pickButton));

   // Assert that data we set up above is shown.
   assertTrue(user.waitForText(phoneNumber));
 }

要将启动的 activity 与 Espresso 意图实际匹配，您需要检查新意图的组件：

intended(hasComponent(NewActivity.class.getName()));

确保在设置中调用 Intents.init() 并在拆卸中调用 Intents.release() 以便能够使用 Espresso 记录意图。
