How to tap on a button inside a CollectionView cell which is not visible on screen

Question

I am working on UITests using XCode. I have multiple CollectionView cells. When I perform Count in the collectionView it shows the certain count. I can able to access first two cells but coming to the 3rd cell as 3(depends on device size). It says that specific button I am looking for in 3rd Cell as exists.

But isHittable is false.

Is there any way I can tap on the button on the 3rd Cell. I have tried using the extension for forceTapElement() which is available online, it didn’t help.

Extension Used:

extension XCUIElement{
    func forceTapElement(){
        if self.isHittable{
            self.tap()
        }else{
            let coordinate: XCUICoordinate = self.coordinate(withNormalizedOffset: .zero)
            coordinate.tap()
        }
    }
}

Tried to perform swipeUp() and access the button. it still shows isHittable as false

Answer 1

The only way I've found is to swipe up untile the isHittable will be true.

app.collectionViews.cells.staticTexts["TEST"].tap()
Thread.sleep(forTimeInterval: 3)

let collectionView = app.otherElements.collectionViews.element(boundBy: 0)
let testAds = collectionView.cells
let numberOfTestAds = testAds.count
if numberOfTestAds > 0 {
    let tester = collectionView.cells.element(boundBy: 2).buttons["ABC"]
    for _ in 0..<100 {
        guard !tester.isHittable else {
            break;
        }
        collectionView.swipeUp()
    }
}

Please note that the swipeUp() method will only move few pixels. If you want to use more comprehensive methods you can get AutoMate library and try swipe(to:untilVisible:times:avoid:from:):

app.collectionViews.cells.staticTexts["TEST"].tap()
Thread.sleep(forTimeInterval: 3)

let collectionView = app.otherElements.collectionViews.element(boundBy: 0)
let testAds = collectionView.cells
let numberOfTestAds = testAds.count
if numberOfTestAds > 0 {
    let tester = collectionView.cells.element(boundBy: 2).buttons["ABC"]
    collectionView.swipe(to: .down, untilVisible: tester)
    // or swipe max 100 times in case 10 times is not enough
    // collectionView.swipe(to: .down, untilVisible: tester, times: 100)
}
