AXElements

AXElements is a DSL abstraction built on top of the Mac OS X Accessibility and CGEvent APIs that allows code to be written in a very natural and declarative style that describes user interactions.

The framework is optimized for writing tests that require automatic GUI manipulation, whether it be finding controls on the screen, typing, clicking, or other ways in which a user can interact with the computer.

Demo

Demo Video

The code from the demo video is right here:

    require 'rubygems'
    require 'ax_elements'

    # Highlight objects that the mouse will move to
    Accessibility.debug = true

    # Get a reference to the Finder and bring it to the front
    finder = app_with_bundle_identifier 'com.apple.finder'
    set_focus_to finder

    # Open a new window
    type "\\COMMAND+n"
    sleep 1 # pause for "slow motion"

    # Find and click the "Applications" item in the sidebar
    window = finder.main_window
    click window.outline.row(static_text: { value: 'Applications' })

    # Find the Utilities folder
    utilities = window.row(text_field: { filename: 'Utilities' })
    scroll_to utilities
    double_click utilities

    # Wait for the folder to open and find the Activity Monitor app
    app = wait_for :text_field, ancestor: window, filename: /Activity Monitor/
    scroll_to app
    click app

    # Bring up QuickLook
    type " "
    sleep 1 # pause for "slow motion"

    # Click the Quick Look button that opens the app
    click finder.quick_look.button(id: 'QLControlOpen')
    sleep 1 # pause for "slow motion"

    # Get a reference to activity monitor and close the app
    activity_monitor = app_with_bundle_identifier 'com.apple.ActivityMonitor'
    terminate activity_monitor

    # Close the Finder window
    select_menu_item finder, 'File', 'Close Window'

Getting Setup

You will need Ruby 1.9.3 or a MacRuby nightly build for installation. You can get help installing Ruby 1.9.3 from the Ruby Website, or help installing MacRuby from the Setup MacRuby guide on Github.

You will also need to make sure you "enable access for assistive devices". This can be done in System Preferences in the Universal Access section:

Universal Access

Then you can install AXElements either from RubyGems or from source. The RubyGems install is as usual, but you may need sudo power:

    gem install AXElements

Or you can install from source:

    cd ~/Documents # or where you want to put the AXElements code
    git clone git://github.com/AXElements/AXElements
    cd AXElements && rake install

Once all the setup is finished, you can start up AXElements in IRB:

    irb -rubygems -rax_elements

NOTE: If you are not using RVM, but are using MacRuby, then you should use macrake instead of rake, and macirb instead of irb, etc.. You may also need to add sudo to your command when you install the gem. If you are not using RVM with MacRuby, but have RVM installed, remember to disable it like so:

    rvm use system

Getting Started

The wiki is the best place to get started, it includes tutorials to help you get started. API documentation is also available on rdoc.info.

Though it is not required, you may want to read Apple's Accessibility Overview as a primer on some the rationale for the accessibility APIs as well as some of the technical the technical underpinnings of AXElements.

Development

Code Climate

AXElements has reached a point where the main focus is stability, documentation, and additional conveniences. It will be out of this world, so we're code naming the next version "Lunatone".

The Moon

Proper releases to rubygems will be made as milestones are reached.

Road Map

There are still a bunch of things that could be done to improve AXElements. Some of the higher level tasks are outlined in various Github Issues. Smaller items are peppered through the code base and marked with @todo tags.

Test Suite

Before starting development on your machine, you should run the test suite and make sure things are kosher. The nature of this library requires that the tests take over your computer while they run. The tests aren't programmed to do anything destructive, but if you interfere with them then something could go wrong. To run the tests you simply need to run the test task:

    rake test

If there is a test that crashes MacRuby then you will need to run tests in verbose mode.

NOTE: There may be some tests are dependent on Accessibility features that are new in OS X Lion which will cause test failures on OS X Snow Leopard. If you have any issues then you should look at the output to find hints at what went wrong and/or log a bug. AXElements will support Snow Leopard for as long as MacRuby does, but I do not have easy access to a Snow Leopard machine to verify that things still work.

Benchmarks

Benchmarks are also included as part of the test suite, but they are disabled by default. In order to enable them you need to set the BENCH environment variable:

    BENCH=1 rake test
