无法在UI测试中访问我的NSMenu

Question

我将NSmenu对象作为statusMenu，我将其辅助功能标识符设置为“ testMenu”

但是当我尝试在下面的UItests中访问它时

        let app = XCUIApplication()
        let menu = app.menus.matching(identifier: "testMenu")
        let count = app.menus.count
        print("menu count is \(count)")
        print("menu count is \(menu.count)")
        if menu.count > 0 {
            XCTAssertTrue(true)
        }
        else {

            XCTAssertTrue(false)
        }

我看到以下错误

`

Replying to query <XCTElementQuery: 0x60c0000a6cc0> with results: (null) (error: Error Domain=com.apple.dt.xctest.automation-support.error Code=2 "No matches found for Find: Elements matching predicate '"testMenu" IN identifiers' from input {(

)}"`
