android - 如何使用 espresso 在 SearchView 上键入文本

Question

TypeText 似乎不适用于 SearchView。

onView(withId(R.id.yt_search_box))
            .perform(typeText("how is the weather?"));

给出错误:

Error performing 'type text(how is the weather?)' on view 'with id:../yt_search_box'

Answer 1

对于任何遇到这个问题的人来说，解决方案是为 SearchView 类型编写一个 ViewAction，因为 typeText 仅支持 TextEditView

这是我的解决方案:

public static ViewAction typeSearchViewText(final String text){
    return new ViewAction(){
        @Override
        public Matcher<View> getConstraints() {
            //Ensure that only apply if it is a SearchView and if it is visible.
            return allOf(isDisplayed(), isAssignableFrom(SearchView.class));
        }

        @Override
        public String getDescription() {
            return "Change view text";
        }

        @Override
        public void perform(UiController uiController, View view) {
            ((SearchView) view).setQuery(text,false);
        }
    };
}
