Sharing accessibility identifiers between app and tests

Published on · Updated on

For identifying views within UI tests we can use accessibility identifiers, which are String values. We can register all of our identifiers within an enum, using an extension to set them on our views. By adding the enum to the app target and the UI test target, an extension can be added to find views within tests suing our ID enum. It's really nice to use an enum, avoiding duplicating the strings and avoiding errors!

App sources

extension UIAccessibilityIdentification {
var viewAccessibilityIdentifier: ViewAccessibilityIdentifier? {
get { fatalError("Not implemented") }
set {
accessibilityIdentifier = newValue?.rawValue

addContactButton.viewAccessibilityIdentifier = .addContactButton

Test sources

extension XCUIElementQuery {
subscript(key: ViewAccessibilityIdentifier) -> XCUIElement {
