generic tap function for XCUIApplication

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

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()
