Make XCUIElement perform 3D touch for Automate UITest?

Question

I\'m creating Automate UITest test case where I\'d like to test the scenario when users make 3D Touch interaction with an element, then shows them Peek and Pop view.

Answer 1

As of Xcode 10 there's no public API to achieve this. However you can use the -[XCUIElement forcePress] private API to simulate a full Peek and Pop interaction. Here's a simple Swift extension that exposes this functionality.

extension XCUIElement {
    func _forcePress() {
        XCTAssert(exists) // Forces the app to idle before interacting
        perform(Selector(("forcePress")))
    }
}

Keep in mind that this is a private API and so may be subject to change/removal in future releases of Xcode. That is, your tests may start crashing when running with a different Xcode version.
