在浓缩咖啡中,我如何测试RecyclerView的*任何*子级是否包含正确的文本

您可以尝试创建自定义 Matcher<View> :

public static Matcher<View> hasItem(Matcher<View> matcher) {
    return new BoundedMatcher<View, RecyclerView>(RecyclerView.class) {

        @Override public void describeTo(Description description) {
            description.appendText("has item: ");
            matcher.describeTo(description);
        }

        @Override protected boolean matchesSafely(RecyclerView view) {
            RecyclerView.Adapter adapter = view.getAdapter();
            for (int position = 0; position < adapter.getItemCount(); position++) {
                int type = adapter.getItemViewType(position);
                RecyclerView.ViewHolder holder = adapter.createViewHolder(view, type);
                adapter.onBindViewHolder(holder, position);
                if (matcher.matches(holder.itemView)) {
                    return true;
                }
            }
            return false;
        }
    };
}

onView(withId(...)).check(matches(hasItem(hasDescendant(withText(...)))))

或者如果您不需要自定义匹配器,也可以使用 RecyclerViewActions.scrollTo() :

onView(withId(...)).perform(scrollTo(hasDescendant(withText(...))))
