Xcode UITest push notification alerts can't click "Allow"

Question

Anyone has had similar situation? So the app open, push notification alerts show up asking if users allow receive push notification, the tests click Don't Allow even I have the following code:

func testClickSystemAlert(){
        let app = XCUIApplication();
        XCUIApplication().alerts["“纳豆行” Would Like to Send You Notifications"].buttons["Allow"].tap()
    }

here is output of print(XCUIApplication().debugDescription);

Answer 1

I end up using this:

addUIInterruptionMonitor(withDescription: "Allow push") { (alerts) -> Bool in
            if(alerts.buttons["Allow"].exists){
                alerts.buttons["Allow"].tap();
            }
            return true;
        }

it will click the Allow buttons

Answer 2

The original answer only works when you add application tapping

addUIInterruptionMonitor(withDescription: "YOUR TITLE") { (alert) -> Bool in
                if alert.buttons["OK"].exists {
                    alert.buttons["OK"].tap()
                }
                return true
            }
XCUIApplication().tap() // which is very important!!!
