Android Espresso:如何匹配盛大的父母？没有给出确切的层次

Question

onView(allOf(withText(activityUnderTest),  withParent(withId(R.id.llh_root_record_activity_3_item)))).check(matches(anything())) ;

在上面的代码片段withParent匹配器失败,因为给出的视图ID不是直接父级而是祖父级.

它可以如下处理,但很想知道这个技巧,特别是当你不想指定下面代码中使用的凌乱层次结构时.

onView(allOf(withText(activityUnderTest),  withParent(withParent(withParent(withId(R.id.llh_root_record_activity_3_item)))))).check(matches(anything())) ;

Answer 1

isDescendantOfA是您所需要的.
实际上,它不适用于大父母.请检查浓缩咖啡备忘单

onView(allOf(withText(activityUnderTest), isDescendantOfA(withId(R.id.llh_root_record_activity_3_item))))
            .check(matches(isDisplayed()));
