I\'ve got a subclass of UIView, let\'s say it\'s class DemoView: UIView { } which contains UILabel and UIButton. I needed to group it and add UIAccessibilityCus
The purpose you're tring to reach isn't possible currently with iOS13 and Xcode 11.
The UITesting framework doesn't access the application code as unit tests do: you can't get an instance to perform selector + the array of custom actions is nil when in UITest ⇒ every custom action isn't reachable and then can't be fired at all.
XCUITEST works thanks to the accessibility properties like accessibilityIdentifier but isn't definitely designed to simply work for VoiceOver (inconceivable and incomprehensible in my view).
I hope that something new with UI testing will be introduced during the next WWDC for REAL accessibility testing.
