How can I set accessibilityIdentifier to UIAlertController?

Question

This is how I simply create UIAlertController and present it on the screen:

private class func showAlertWithTitle(title: String, message: String) {

    let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    //alert.accessibilityLabel = "my string here"      //doesnt work
    let action = UIAlertAction(title: "OK", style: .Default) { action in
        alert.dismissViewControllerAnimated(true, completion: nil)
    }

    alert.addAction(action)
    UIStoryboard.topViewController()?.presentViewController(alert, animated: true, completion: nil)
}

and this is how I access it under UITests:

emailAlert = app.alerts["First Name"] //for title "First Name"

but I would like to set there custom identifier and access this by firstName like this:

emailAlert = app.alerts["firstName"]

Is it possible?

Answer 1

This is an old thread but someone might use this.

I was able to set the accessibility identifier like this:

let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
alert.view.accessibilityIdentifier = "custom_alert"
alert.view.accessibilityValue = "\(title)-\(message)"

alert.addAction(
    UIAlertAction(
        title: "ALERT_BUTTON_OK".localized,
        style: .default,
        handler: handler
    )
)

present(alert, animated: true)

That way I can access the alert by accessibility identifier and check its contents in accessibility value.

It is not perfect of course, but it works - at least for my testing using Appium.
