Espresso: no hierarchy views found matching id: android: id / home

Question

When I run my test case, I got the following exception.

android.support.test.espresso.NoMatchingViewException: no views in hierarchy match found: with id: android: id / home

This is my TestCase code.

 public void nav_to_alarm_test(){
        onView(withId(R.id.navigation_notifications)).perform(click());
        onView(withId(R.id.rl_reminder)).perform(click());
        onView(withId(R.id.item_test)).perform(click());
        onView(withId(android.R.id.home)).perform(click());//throw exception here
        onView(withId(android.R.id.home)).perform(click());
    }

This is android.R.id.home, belongs to a button provided by ActionBar

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                finish();
                return true;
            case R.id.item_test:
                startActivityForResult(CreateOrUpdateReminderActivity.class,CMD_ADD_REMINDER);
                return true;
            default:
                return super.onOptionsItemSelected(item);

        }
    }

Why can't I find the views in the hierarchy for the id of the android.R.id.home resource? I have Google my problem, but the answers are not what I want.
Thanks for any help.
