generic tap function for XCUIApplication - ios

Question

We are trying to migrate from UIAutomation to XCUITests.
For the UIAutomation we came up with a handy 'tapOnName' function which just crawled thru a whole sub element tree and tapped on the element with the first match.
function log(msg) {
UIALogger.logDebug(msg);
}
//recursive function crawling thru an elements hierarchy
//and tapping on the first match of accessibilityIdentifier
//or button text
function tapOnNameWithRoot(name,el) {
if (el.name()==name && el.isVisible()) {
log("tap on itt!!!")
el.tap();
return true;
}
if (el.toString()=="[object UIAButton]" && el.label()==name) {
log("tap on Button!!!")
el.tap();
return true;
}
var elements=el.elements();
if (elements===null || elements===undefined) {
log("elements null or undefined for:"+el.toString());
return false;
}
for(var i=0,len=elements.length ;i<len;i++) {
if (tapOnNameWithRoot(name,elements[i])) {
return true;
}
}
return false;
}
var win = UIATarget.localTarget().frontMostApp().mainWindow();
//for ex taps on a button with the text "pushme" in the
//main UIWindow
tapOnNameWithRoot("pushme",win);
No the question : is it possible to implement the same function using XCUIApplication ?

Answer 1

There is shorthand support for this function in XCTest.
For tapping the first match out of any element, you can get all elements and tap the first one:
let app = XCUIApplication()
let element = app.descendentsMatchingType(.Any)["someIdentifier"]
element.tap()
If you know what type of element it is going to be, it's better to filter by that type first:
let app = XCUIApplication()
let element = app.buttons["someIdentifier"]
element.tap()

Answer 2

Are you looking for something like this:
func tapBasedOnAccessibilityIdentifier(elementType elementType: XCUIElementQuery, accessibilityIdentifier: String) {
var isElementExist = false
for element in elementType.allElementsBoundByIndex {
if element.label == accessibilityIdentifier {
element.tap()
isElementExist = true
break
}
}
if !isElementExist {
XCTFail("Failed to find element")
}
}
where you call the method in the test like:
tapBasedOnAccessibilityIdentifier(elementType: app.staticTexts, accessibilityIdentifier: "Accessibility Identifier")
You can tweak it a little so that it cover all the requirements.
