swift - 无法使用 doubleTap() 进行简单的 UI 测试 (macOS)

Question

我ContentView在 Mac App 项目上有这个简单的：

struct ContentView: View {
    @State var isPresented: Bool = false
    var body: some View {
        HStack {
            CustomView()
                .frame(minWidth: 150, idealWidth: 150, maxWidth: 150, minHeight: 100, idealHeight: 100, maxHeight: 100, alignment: /*@START_MENU_TOKEN@*/.center/*@END_MENU_TOKEN@*/)
                .contentShape(Rectangle())
                .accessibility(identifier: "touch1")
                .onTapGesture(count: 2){
                    isPresented = true
                }
        }
        .alert(isPresented: $isPresented) {
            let alert = Alert(title: Text("Double Clicked"))
            return alert
        }
    }
}

struct CustomView: View {
    var body: some View {
        VStack{
            Image(systemName: "cursorarrow.click.2")
        }
    }
}

然后我想为它写一个 UI 测试：

    func testExample() throws {
        // UI tests must launch the application that they test.
        let app = XCUIApplication()
        app.launch()

        XCTAssert(app.images["touch1"].isHittable)
        
        app.images["touch1"].doubleTap()

        // Use recording to get started writing UI tests.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
        
        XCTAssertTrue(app.alerts["Double Clicked"].waitForExistence(timeout: 1))
    }

当我运行测试时，警报不显示，但鼠标光标在我的按钮中间移动，这让我认为app.images["touch1"]是有效的。

有人用doubleTap()吗？没有它我如何 UI 测试我的应用程序？
