Xcode UI test - UI Testing Failure - Failed to scroll to visible (by AX action) when tap on Search field "Cancel' button

Question

I am trying to dismiss the search field by tapping 'Cancel' button in search bar.

The test case is failing to find the cancel button. It was working fine in Xcode 7.0.1

I have added predicate to wait for button to appear. The test case is failing when we tap of "cancel" button

let button = app.buttons[“Cancel”] let existsPredicate = NSPredicate(format: "exists == 1")  expectationForPredicate(existsPredicate, evaluatedWithObject: button, handler: nil) waitForExpectationsWithTimeout(5, handler: nil)  button.tap() // Failing here 

logs:

I guess here "Cancel" button returns false for hittable property, that is preventing it from tapping.

If you see tap() in documentation it says

/*!  * Sends a tap event to a hittable point computed for the element.  */ - (void)tap; 

It seems things are broken with Xcode 7.1. To keep myself (and you too ;)) unblocked from these issues I wrote an extension on XCUIElement that allows tap on an element even if it is not hittable. Following can help you.

/*Sends a tap event to a hittable/unhittable element.*/ extension XCUIElement {     func forceTapElement() {         if self.hittable {             self.tap()         }         else {             let coordinate: XCUICoordinate = self.coordinateWithNormalizedOffset(CGVectorMake(0.0, 0.0))             coordinate.tap()         }     } } 

Now you can call as

button.forceTapElement() 

Update - For Swift 3 use the following:

extension XCUIElement {     func forceTapElement() {         if self.isHittable {             self.tap()         }         else {             let coordinate: XCUICoordinate = self.coordinate(withNormalizedOffset: CGVector(dx:0.0, dy:0.0))             coordinate.tap()         }     } }
