Overview

UI Testing Cheat Sheet

This repository is complementary code for my post, UI Testing Cheat Sheet and Examples. The post goes into more detail with example images for most examples.

The included project highlights working code with a simple Test Host. This was last updated for Swift 5 on Xcode 11.4.1.

Contents

Basic Functionality

Testing if an element exists

XCTAssert(app.staticTexts["Welcome"].exists)

Testing if text with an ellipsis exists

A full text match will find an element even if the displayed text has an ellipsis due to truncation.

let longNameCell = app.staticTexts["Adolph Blaine Charles David Earl Frederick Gerald Hubert Irvin John Kenneth Lloyd Martin Nero Oliver Paul Quincy Randolph Sherman Thomas Uncas Victor William Xerxes Yancy Wolfeschlegelsteinhausenbergerdorff, Senior"]
XCTAssert(longNameCell.exists) // displayed text is "Adolph Blaine Charles David Earl Freder..."

Waiting for an element to appear

"Waiting" is now built into XCTest.

let goLabel = app.staticTexts["Go!"]
XCTAssertFalse(goLabel.exists)

app.buttons["Ready, set..."].tap()
XCTAssert(goLabel.waitForExistence(timeout: 5))

Interacting with System Controls

Tapping buttons

Identify buttons by their accessibility label.

app.buttons["Add"].tap()

Typing text

First make sure the text field has focus by tapping on it.

let textField = app.textFields["Username"]
textField.tap()
textField.typeText("joemasilotti")

Dismissing alerts

app.alerts["Alert Title"].buttons["Button Title"].tap()

Dismissing action sheets

app.sheets["Sheet Title"].buttons["Button Title"].tap()

Handling system alerts

Present a location services authorization dialog to the user and dismiss it with the following code.

Before presenting the alert add a UI Interruption Handler. When this fires, dismiss with the "Allow" button.

Bool in alert.buttons["Allow"].tap() return true } app.buttons["Request Location"].tap() app.tap() // need to interact with the app again for the handler to fire "> 
addUIInterruptionMonitor(withDescription: "Location Services") { (alert) -> Bool in
  alert.buttons["Allow"].tap()
  return true
}

app.buttons["Request Location"].tap()
app.tap() // need to interact with the app again for the handler to fire

Sliding sliders

This will slide the value of the slider to 70%.

app.sliders.element.adjust(toNormalizedSliderPosition: 0.7)

Interacting with pickers

A picker with one wheel:

app.pickerWheels.element.adjust(toPickerWheelValue: "Picker Wheel Item Title")

A picker with multiple wheels. Make sure to set the accessibility delegate so the framework can identify the different wheels.

let firstPredicate = NSPredicate(format: "label BEGINSWITH 'First Picker'")
let firstPicker = app.pickerWheels.element(matching: firstPredicate)
firstPicker.adjust(toPickerWheelValue: "first value")

let secondPredicate = NSPredicate(format: "label BEGINSWITH 'Second Picker'")
let secondPicker = app.pickerWheels.element(matching: secondPredicate)
secondPicker.adjust(toPickerWheelValue: "second value")

Tapping links in web views

app.links["Tweet this"].tap()

Interactions

Verifying the current controller's title

XCTAssert(app.navigationBars["Details"].exists)

Reordering table cells

If you have a UITableViewCell with default style and set the text to "Title", the reorder control's accessibility label becomes "Reorder Title".

Using this we can drag one reorder control to another, essentially reordering the cells.

let topButton = app.buttons["Reorder Top Cell"]
let bottomButton = app.buttons["Reorder Bottom Cell"]
bottomButton.press(forDuration: 0.5, thenDragTo: topButton)

XCTAssertLessThanOrEqual(bottomButton.frame.maxY, topButton.frame.minY)

Pull to refresh

Create a XCUICoordinate from the first cell in your table and another one with a dy of six. Then drag the first coordinate to the second.

let firstCell = app.staticTexts["Adrienne"]
let start = firstCell.coordinate(withNormalizedOffset: (CGVectorMake(0, 0))
let finish = firstCell.coordinate(withNormalizedOffset: (CGVectorMake(0, 10))
start.press(forDuration: 0, thenDragTo: finish)

Pushing and popping view controllers

Test if a view controller was pushed onto the navigation stack.

app.buttons["More Info"].tap()
XCTAssert(app.navigationBars["Volleyball?"].exists)

Pop a view controller by tapping the back button in the navigation bar and assert that the title in the navigation bar has changed.

app.navigationBars.buttons.elementBoundByIndex(0).tap()
XCTAssert(app.navigationBars["Volley"].exists)

  • Simulate a Double Press on Home Button

    Simulate a Double Press on Home Button

    I'm trying to simulate double pressing the home button to launch the so-called app switcher. However, it looks like - (void)pressButton:(XCUIDeviceButton)button; is not synchronous and calling

    
[[XCUIDevice sharedDevice] pressButton:XCUIDeviceButtonHome];

    would launch the home screen any way regardless of how quick the subsequent press follows. Any idea or tips on how to accomplish this?

  • Finding Search Bar embedded inside a navigation bar in iOS 11.

    Finding Search Bar embedded inside a navigation bar in iOS 11.

    This repo has been exceptionally helpful. Thanks for making this.

    I've been running into a pickle especially while testing search on VCs in iOS 11 where the search bar is embedded inside a navigation bar. Neither app.searchFields or any child element under app.navigationBar reveal the relevant XCUIElement.

    Is there a workaround for this?

  • Swift 3 migration

    Swift 3 migration

    The migration is complete 😄, but two tests are broken and I can't figure out what's wrong with them, so sending this over hoping it's just an easy thing that I overlooked.

    I made the commits as atomic as possible, tackling pre-migration warnings before the actual Xcode8 migration.

    There are many Storyboard changes, but functionality didn't change, Xcode forces you to select a device and update the views to reflect that viewport.

  • Localization

    Localization

    I'm working on using Fastlane:Snapshot, and this projects is a great guide. But I am wondering how to target alerts in different languages when the text or button text isn't the same. IE, app.alerts["You won!"].buttons["Awesome!"].tap() or addUIInterruptionMonitorWithDescription("Location Services") { (alert) -> Bool in alert.buttons["Allow"].tap() return true } Especially considering the system alert buttons might not be the same translation even if I have NSLocaliazedString...

    Question - Does the DismissingASystemAlert work on an actual device or just the simulator

    I was using your example and it works great on the simulator but I am not able to get the alert to be dismissed on an actual iPad Air 2 device. I think I remember reading somewhere that alerts are not being dismissed on ipad devices - only phones.

  • Question - Do you run all of the tests at one time or run them individually

    Question - Do you run all of the tests at one time or run them individually

    Thanks so much for the information you provide on UI Testing and XCode 7. I have found it very useful in helping me learn how to write UI Tests.

    I have seen several notes that tests should be stand alone. I downloaded this Volley project and if I run the tests individually - one at a time, they all work. But If I try to run all of them starting at the top, only one or two of them will pass.

    So would it be better to run the tests one at a time in general?

    Thanks

  • Webview Test Elements

    Webview Test Elements

    Hello! I think it's not the best place to ask this question but I was trying to figure out the issue. I was testing (XCUITest) a Webview (Load an Angular Page). I ran the test with this code line:

    let propertiesButton = app.webViews.otherElements.element(boundBy: 3).firstMatch if propertiesButton.exists { propertiesButton.tap() }

    Properties Window opened fine only in Simulator iPhone 11 - 13.1. If I run the same test with another Simulator like iPhone 11 Pro - 13.1 or 13.3 the tap() doesn't work.

    Also this line: app.swipeUp() when the Properties Window is opened, only works in Simulator iPhone 11 - 13.1

    I'm not sure if the issue will be from how the web view render the Angular page (CSS). Does anybody have or had the same issue?
