XCUItest addUIInterruptionMonitor is not capturing alerts on iOS14 simulator and xcode 12

Question

override func setUp() {
    addUIInterruptionMonitor(withDescription: "App store alert") { (alert) -> Bool in
        alert.buttons.element(boundBy: 0).tap()
        return true
         }
}


func test() {
    functionThatCausesAlertToAppear()
    XCUIApplication().tap()
}

When I attempt to print a statement within the addUIInterruptionMonitor it doesn't print leading me to believe that the block isn't triggered.

Answer 1

Although this does not solve the issue at hand I've found a workaround from: addUIInterruptionMonitor(withDescription:handler:) not working on iOS 10 or 9

let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") 

let allowBtn = springboard.buttons["Allow"]
if allowBtn.waitForExistence(timeout: 10) {
    allowBtn.tap()
}

If you are running into the issue where your interruption is not firing even after making sure the code is correct, then read this documentation on Apple website - Handling UI Interruptions.

I too faced this challenge, and after realizing the issue, i simply identified the OK button and tapped on it in the flow.

Hope this helps in your case too!
