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

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)
}
