问题描述
有人会知道如何在android espresso中测试Toast消息的外观吗?在robotium中，它的易用性我曾经用过但开始在意式浓缩咖啡中工作，但没有得到确切的命令.
Would anyone know how to test for the appearance of a Toast message in android espresso? In robotium its easy & I used but started working in espresso but dont getting the exact command.
推荐答案
这个稍长的语句对我有用:
This slightly long statement works for me:
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.RootMatchers.withDecorView;
import static android.support.test.espresso.matcher.ViewMatchers.isDisplayed;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
import static org.hamcrest.Matchers.is;
import static org.hamcrest.Matchers.not;
....
onView(withText(R.string.TOAST_STRING)).inRoot(withDecorView(not(is(getActivity().getWindow().getDecorView())))).check(matches(isDisplayed()));
