I can find a solution but it is not very nice. It seems there is no API to trigger the statusbar directly. The following is suggested by ChatGPT import XCTest import CoreGraphics func moveMouseToTop() { let screenHeight = NSScreen.main?.frame.height ?? 900 let topPoint = CGPoint(x: 100, y: 2) // Move near the top edge let move = CGEvent(mouseEventSource: nil, mouseType: .mouseMoved, mouseCursorPosition: topPoint, mouseButton: .left) move?.post(tap: .cghidEventTap) } class StatusBarTests: XCTestCase { func testClickStatusBarIcon() { let app = XCUIApplication(bundleIdentifier: "your.app.bundle.identifier") app.launch() moveMouseToTop() // Ensure status bar is visible let statusBar = XCUIApplication(bundleIdentifier: "com.apple.systemuiserver") let statusBarItem = statusBar.menuBars.children(matching: .button).element(boundBy: 0) // Adjust index for your icon XCTAssertTrue(statusBarItem.exists) statusBarItem.click() } }
