android - Android Espresso 测试匹配器 withId 在 ActionBarContextView 中返回 null

问题描述

当我的 ActionBarContextView 显示时，我正在尝试添加浓缩咖啡测试。

在此处输入图像描述

问题是当我尝试通过 id 查找视图时，视图为空。

onView(allOf(withId(R.id.action_mode_bar),withText(actionBarTitle))).check(matches(isDisplayed()))

我也试试

onView(isAssignableFrom(ActionBarContextView::class.java)).check(matches(isDisplayed()))

并且文本ID失败。但是在 ViewHistroy 中，视图被列在那里。

如果我尝试仅通过文本查找视图，它可以工作。但我需要通过 ID 找到它以检查视图何时可见以及何时消失

解决方案

你可能误解allOf了anyOf. action_mode_bar是 a ActionBarContextView，这就是为什么allOf当你使用它时失败的原因withText，它只适用于TextView. 所有匹配器必须在一个匹配器中allOf匹配，例如action_bar_titleand withText：

onView(allOf(withId(R.id.action_bar_title), withText(actionBarTitle))).check(matches(isDisplayed()))
