How to test UIImageView elements in iOS XCTest?

Question

I'm trying to test my UIs using XCTest UI testing, and having troubles of testing UIImageViewsI have in my app (hit tests, presence etc).

In the list of the XCUIElementType there is no such type, and when I look at the children of the superview my UIImageViews are not listed there for some reason eventhough I can see them on screen and in the UI inspector in the Xcode.

Has anyone had this kind of problem?

Assert the presence of an image by its accessibility label.

Production Code

let image = UIImage(named: "profile")
let imageView = UIImageView(image: image)
imageView.accessibilityIdentifier = "Your profile image"

UI Test Code

let app = XCUIApplication()
XCTAssert(app.images["Your profile image"].exists)

what if the imageView is a subview of the dynamic cell prototype ? – Quandary

oh actually, I see how I can test for existence! Cool, what about tapping on it? I have the gesture recognizer attached to the imageView? – Quandary

figured XCUIElement* image = self.app.images[@"addToGroupButton1"]; [image tap]; thank you! – Quandary

@Joe Masilotti Do you know how to check whether the image itself, instead of the imageView, does exist? thx. – Resignation
