User Profile

I'm almost at the beginning of Swift programming education. Now i'm trying to create UI tests for my app. I can't find popover in application's elements tree. It's statusbar application and popover is the main UI but it's completely missed for testing framework…Popover created programatically using UI from storyboard. In `AppDelegate.swift` i have this code:@NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate { let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.squareLength) let popover = NSPopover() func applicationDidFinishLaunching(_ aNotification: Notification) { stopAutostarter() if let button = statusItem.button { button.image = NSImage(named: NSImage.Name("StatusBarButtonImage")) button.action = #selector(togglePopover(_:)) } popover.contentViewController = PopoverViewController.freshController() popover.behavior = .transient popover.setAccessibilityEnabled(true) statusItem.button?.setAccessibilityEnabled(true) syncIcon() } @objc func togglePopover(_ sender: Any?) { if popover.isShown { closePopover(sender: sender) } else { showPopover(sender: sender) } } func showPopover(sender: Any?) { if let button = statusItem.button { popover.show(relativeTo: button.bounds, of: button, preferredEdge: NSRectEdge.minY) } } func closePopover(sender: Any?) { popover.performClose(sender) } }My `PopoverViewController.swift` (where PopoverViewController.mainView is slightly modified NSView just to return `true` in `acceptsFirstResponder`):class PopoverViewController: NSViewController { @IBOutlet weak var mainView: RespondingView! override func viewDidLoad() { super.viewDidLoad() mainView.setAccessibilityEnabled(true) mainView.setAccessibilityRole(.window) mainView.setAccessibilityIdentifier("PopoverView") } static func freshController() -> PopoverViewController { let storyboard = NSStoryboard(name: "Main", bundle: nil) let identifier = NSStoryboard.SceneIdentifier("PopoverViewController") guard let viewcontroller = storyboard.instantiateController( withIdentifier: identifier) as? PopoverViewController else { fatalError("Why can't i find PopoverViewController? - Check Main.storyboard") } return viewcontroller } }So now, when i try to record clicking buttons placed in popover in UI tests i've got error: "Recorder Service Error: Left Mouse Down: Failed to find matching element"When i try analyze application - it's just not have my ppover in elements tree. Only main menu bar, touch bar and menu bar with statusbar button Which is not contains popover.po XCUIApplication() t = 91.06s Snapshot accessibility hierarchy for app with pid 62106 t = 91.16s
