Answer 1

If you have an AlertDialog like that:

You can check if the components are displayed:

int titleId = mActivityTestRule.getActivity().getResources()
        .getIdentifier( "alertTitle", "id", "android" );

onView(withId(titleId))
        .inRoot(isDialog())
        .check(matches(withText(R.string.my_title)))
        .check(matches(isDisplayed()));

onView(withId(android.R.id.text1))
        .inRoot(isDialog())
        .check(matches(withText(R.string.my_message)))
        .check(matches(isDisplayed()));

onView(withId(android.R.id.button2))
        .inRoot(isDialog())
        .check(matches(withText(android.R.string.no)))
        .check(matches(isDisplayed()));

onView(withId(android.R.id.button3))
        .inRoot(isDialog())
        .check(matches(withText(android.R.string.yes)))
        .check(matches(isDisplayed()));

and perform an action:

onView(withId(android.R.id.button3)).perform(click());
