UIAutomation on iPad

Posted in Apple, mobile, QA by AltF on November 17, 2010

UIAutomation is only available in iOS 4.0+ SDK – so to run UIAutomation on the iPad make sure your application is compiled to run on 4.x simulator/device. You will need to download the latest version of the SDK to get the 4.x version of the iPad Simulator (also you can upgrade your device firmware to 4.x to run on the device). Download the latest version of the SDK from Apple Dev Center.

Refer to my previous post “Automating iOS User Interface Testing with UIAutomation” for getting started with UIAutomation.

For those of you who are still getting the error like “Automation is not available for this version of the iPhone Simulator.” when trying to run UIAutomation on iPad Simulator – please check the following things:

1. Ensure that you build your application for the correct version of iOS SDK. Select iOS 4.x as Base SDK in the project info before building.

2. Also ensure that the Instruments is running the application on the correct version of iPad Simulator. Select your application in the “Choose Target” and select the correct version of iPad Simulator under “Launch Options” (by default it’s selected to iPad Simulator 3.2, change that to iPad – Simulator – iOS 4.x)

Once you have selected iOS 4.x in Instruments – you should be able to run your UIAutomation scripts on the iPad Simulator.


Automating iOS User Interface Testing with UIAutomation

Posted in Apple, mobile, QA by AltF on November 14, 2010

Update: 25 June 2011
iOS 5 now supports recording these user interactions in UIAutomation which means no need to write these scripts manually.

Apple included Automated Testing support in iOS 4.0 which lets you automate testing of your iOS applications by scripting touch events. It allows you to write test scripts to exercise your application’s user interface elements as the application runs on a connected device or simulator. You write the tests in JavaScript to the UI Automation API, which simulates user interaction with the application as it runs and returns log information to the host computer.

In a nutshell:
– Automates UIKit based applications.
– Works on all iOS devices (iPhone, iPod Touch, iPad) and simulator.
– JavaScript automation scripts.
– Integrated in Instruments.
– Accessibility based.

Step 1 – Getting Started.
– Make sure that you have the latest iOS SDK (4.0+) installed | iOS SDK
– Familiarize yourself with Instruments | Instruments User Guide

Step 2 – Preparing your application.
Ensure accessibility is enabled and all the UI controls and views in your application are tagged with unique accessibility labels which makes it easy to access them in our test scripts. Using Interface Builder, you can set an element’s accessibility status and provide custom content for the label.

Step 3 – Writing test scripts.
In essence, your test script is an ordered set of commands, each of which accesses a user interface element in your application to perform a user action on it or to use the information associated within it. All the user interface elements in your application are represented to the script through an ordered hierarchy of objects defined by the UIAElements class and its subclasses.
To reach a specified UI element, the script simply calls down the element hierarchy, starting with the top level target object obtained by calling UIATarget.localTarget() The control hierarchy looks like:

var target = UIATarget.localTarget();
var application = UIATarget.localTarget().frontMostApp();
var window = UIATarget.localTarget().frontMostApp().mainWindow();

For example, if your application has a table view in the main window the hierarchy should looks like:
• Target application ■ Main window ■ View

Similarly, within a view there are elements:
• Target application ■ Main window ■ View ■ Element

And to access the child elements within an element:
• Target application ■ Main window ■ View ■ Element ■ Child element

The Automation instrument maintains a complete element hierarchy that represents your application’s user interface. To view that hierarchy, use the logElementTree method to write an outline of it to the log:

Once you are able to access the elements you can perform various actions on it. I’ll show you how to simulate basic touch events.

Tapping buttons:
Example: If you want to tap on the Add button on the top navigation bar. (Note that the navigation bar is outside the main window, hence we access it via:)

Scrolling to an element:
Example: If your main application is an address book app, with the main window consisting of a tableview with elements in it. You can simply scroll to a particular element:
window.tableViews()[0].scrollToElementWithName("John Appleseed");

You can write a few assertion functions to verify if the expected results matches the actual results. You can log the results based on pass/fail. Simple example:

var testName = "Test Case 1";
UIALogger.logMessage("Assert Text - Check if element 5 is John Appleseed");
var expected = "John Appleseed";
var actual = window.tableViews()[0].cells()[5].elements()[5].name());
if (expected = actual) {
else {

Step 4 – Executing the test.
– Once you are ready with the test script. Compile your app in the debug mode and create a simulator build.
– Launch Instruments and select Automation from iOS Simulator templates.
– Select your target application from “Choose Target” option on the top.
– Select the test script from “Choose Script” option on the left window.
– Hit the red record button once done. It will fire up the simulator with your target app and start executing the tests.

Working with Watir on a mac

Posted in QA by AltF on July 9, 2010

Watir on a Mac can be used either with FireWatir, or SafariWatir, but not Watir itself because it has IE requirements.


1. Check if you have ruby installed on your mac. (Recommended Ruby 1.8.6)

ruby -v

2. Install firewatir

sudo gem update --system
sudo gem install firewatir

3. Install plugin in your browser (Mac plugin for Firefox 3.6)

4. Start firefox with ssh option from command line

/Applications/ -jssh

5. Sample script

require 'rubygems'
require 'firewatir'
