Android UIAutomator/espresso : open browser on a specific URL

Question

我正在玩弄 UIAutomator/espresso 和我的应用程序。其实我想做以下事情:

1. 对我的应用程序执行一些操作/检查

2. 打开默认浏览器访问 URL

3. 返回我的应用程序并重新检查界面

实际上我做不到第 2 步。 以下是我尝试过的不同方式:

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://stackoverflow.com/"));

mActivityTestRule.launchActivity(browserIntent);
InstrumentationRegistry.getTargetContext().sendBroadcast(browserIntent);
InstrumentationRegistry.getInstrumentation().startActivitySync(browserIntent);

我在 Stack Overflow 上搜索过，但还没有找到解决方案。

@LargeTest
@RunWith(AndroidJUnit4.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class BackgroundForegroundTest {

    @Rule
    public ActivityTestRule<MainActivity> mActivityTestRule = new ActivityTestRule<>(MainActivity.class);

    private UiDevice mDevice;

    @Before
    public void before() {
        // Initialize UiDevice instance
        mDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());

        assertThat(mDevice, notNullValue());
    }

    @Test
    public void testOpenBrowserAndSwitchBack() throws InterruptedException {
        onView(withId(R.id.text1)).check(matches(isDisplayed()));

        Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://stackoverflow.com/"));
        mActivityTestRule.launchActivity(browserIntent);
        Thread.sleep(8000);

        getBackToApp("My App");

        onView(withId(R.id.text1)).check(matches(isDisplayed()));
    }

    private void getBackToApp(String appDescription){
        try {
            mDevice.pressRecentApps();
            UiSelector selector = new UiSelector();
            UiObject recentApp = mDevice.findObject(selector.descriptionContains(appDescription));
            recentApp.click();
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (UiObjectNotFoundException e) {
            e.printStackTrace();
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
}

好的，伙计们，我想通了。这是解决方案:

Context context = InstrumentationRegistry.getInstrumentation().getContext();
Intent intent = context.getPackageManager().getLaunchIntentForPackage("com.android.chrome");
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.setData(Uri.parse("https://stackoverflow.com/"));
context.startActivity(intent);
mDevice.wait(Until.hasObject(By.pkg("com.android.chrome").depth(0)), TIMEOUT);
