问题描述
我想支持VoiceOver。我在 UITableViewCell 里面有一个 UIButton 。根据最佳实践，我禁用了可访问性按钮（ .isAccessibilityElement = false ），并为该单元实现了自定义可访问性操作（ accessibilityCustomActions，NSAccessibilityCustomAction ）。
I want to support VoiceOver. I have an UIButton inside of an UITableViewCell. According to a best practice I have disabled the button for accessibility (.isAccessibilityElement = false) and implemented a custom accessibility action for the cell (accessibilityCustomActions, NSAccessibilityCustomAction).
通过这种方式，VoiceOver不会找到并读取按钮作为自己的元素。为了使按钮后面的功能可访问，我向该单元格添加了一个自定义可访问性操作。使用自定义动作，用户可以上下滑动来选择动作。然后双击来执行它。
This way VoiceOver would not find and read the button as an own element. To make the feature behind the button accessible, I have added a custom accessibility action to the cell. With the custom action the user can select the action with swipe up and down. And then perform it with double-tap.
现在，我想使用UITest测试此操作。无法访问UITest内部的按钮，因为它的可访问性已被禁用。
Now I want to test this action with an UITest. It's not possible to access the button inside of an UITest, because its disabled for accessibility.
如何在UITest内部执行自定义可访问性操作？
How can I perform a custom accessibility action inside of an UITest?
推荐答案
实际上，您不能使用{Xcode 11，iOS 13}，即使您可以在UITest中获得一系列动作，它也为零并且您无法从XCUITEST 中触发选择器（UI测试无法像单元测试那样获得对应用程序的代码级访问）。
Actually, you can't with {Xcode 11, iOS 13} and even if you can get an array of actions in UITest, it's nil and you can't fire the selectors from XCUITEST (UI tests don't get code-level access to the app as unit tests do).
手动测试是当前使用VoiceOver测试辅助功能自定义操作的唯一方法。
Testing manually is currently the only way to test accessibility custom actions with VoiceOver.
