Я пытаюсь запустить тесты пользовательского интерфейса для своего приложения macOS какао. Однако при выполнении следующего теста, который проверяет производительность запуска моего приложения, тесты каждый раз терпят неудачу:
func testLaunchPerformance() throws {
if #available(macOS 10.15, *) {
// This measures how long it takes to launch your application.
measure(metrics: [XCTOSSignpostMetric.applicationLaunch]) {
XCUIApplication().launch()
}
}
}
Печатается следующее сообщение об ошибке. Я предполагаю, что это говорит о том, что у моего приложения нет полных метаданных при одном из нескольких запусков приложения?!
