Android UIAutomator/espresso:在特定URL上打开浏览器

Question

我正在玩UIAutomator/espresso和我的应用程序。实际上我想做以下几点：

1. 对我的应用程序执行一些操作/检查

2. 打开默认浏览器以查找网址

3. 返回我的应用程序并重新检查界面

实际上我无法完成第 2 步。以下是我尝试的不同方法：

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://stackoverflow.com/"));
mActivityTestRule.launchActivity(browserIntent);
InstrumentationRegistry.getTargetContext().sendBroadcast(browserIntent);
InstrumentationRegistry.getInstrumentation().startActivitySync(browserIntent);

我在堆栈溢出上搜索，但尚未找到解决方案。

@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();
        }
    }
}

Answer 1

好吧，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);
