Answer 1

For notifications:

    private UiObject getNotificationStackScroller()
{
    /*
     * access Notification Center through resource id, package name, class name.
     * if you want to check resource id, package name or class name of the specific view in the screen,
     * run 'uiautomatorviewer' from command.
     */
    UiSelector notificationStackScroller = new UiSelector().packageName("com.android.systemui")
            .className("android.view.ViewGroup")
            .resourceId(
                    "com.android.systemui:id/notification_stack_scroller");
    UiObject notificationStackScrollerUiObject = mDevice.findObject(notificationStackScroller);
    assertTrue(notificationStackScrollerUiObject.exists());

    return notificationStackScrollerUiObject;
}

and the access any "i-th" item through:

UiObject notificationUiObject = getNotificationStackScroller().getChild(new UiSelector().index(i));
        assertTrue(notificationUiObject.exists());

and for example check if number of notifications is "3" exits:

            UiObject numberOfNotifications = notificationUiObject.getChild(new UiSelector().text("3"));
        assertTrue(numberOfNotifications.exists());

Answer 2

The UiDevice.openNotification method, added in API level 18, will programmatically open the notification drawer.

Usage Example

@RunWith(AndroidJUnit4.class) 
public class ExampleInstrumentedTest {

    @Test
    public void useAppContext() throws Exception {

        Context appContext = InstrumentationRegistry.getTargetContext();
        assertEquals("com.mydomain.myuiautomatortests", appContext.getPackageName());

        appContext.startActivity(new Intent(appContext, MainActivity.class));

        UiDevice mDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
        mDevice.openNotification();
    }
}

Gradle Dependency

compile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2'  // or higher
