A simple framework that helps to create functional and UI tests against almost any macOS application.

• Created to help testers to automate their routine tasks with ease and help me with structuring my experience;
• I'll be glad to receive suggestions on evolution of the project!

• Allow Accessibility access in a Security&Privacy pane of System Preferences;
• You might be asked to allow various access rights anyway, those are new macOS restrictions you cannot easily avoid from Python, just allow them;
• When calling ObjC mouse wrapper a Python Launcher will show up in Dock. To avoid this behavior, you need to add LSUIElement -string "1" to a Python.app property list. Mine was located easily by running brew --prefix python3. It'll be under Frameworks -> Python.framework -> Resources;
• Get UI Browser app, it helps to locate AppleScript locators of the elements on your screen, very helpful;

• Installation
• Features
• Examples

• Install a modern Python version (at least 3.6): brew install python3
• If OCR capabilities required, install Tesseract: brew install tesseract
• Update pip's setup tools: pip3 install --upgrade pip setuptools wheel
• Install the package: pip3 install macuitest and you should be ready to go

• Many of useful operations on macOS are introduced in a macuitest.lib.operating_system package. A macos module inside the package will allow you to manipulate files, processes, change some system settings, etc.;
• An application module inside macuitest.lib.apps may describe almost any GUI macOS app. Creating an instance of which will allow you to perform launch/quit operations, read some of its attributes, have basic control over its main window, etc.;
• applescript_wrapper module under macuitest.lib.applescript_lib allows to run some AppleScript commands;
• And last but not least, you can describe most if not every element of an application using applescript_element, native_element and ui_element modules inside macuitest.lib.elements. They allow working with AppleScript, PyObjC translated (Native) and UI (built on screenshots) elements retrospectively.

from macuitest.lib.apps.application import Application
from macuitest.lib.elements.applescript_element import ASElement

test_app = 'Calculator'
calculator = Application(test_app)

button_one = ASElement('button "1" of group 2 of window 1', process=test_app)
button_zero = ASElement('button "0" of group 2 of window 1', process=test_app)
input_field = ASElement('static text 1 of group 1 of window 1', process=test_app)

calculator.launch()
button_one.click_mouse()
button_zero.click_mouse()
button_one.click_mouse()
assert input_field.text == '101'  # Hopefully you get 101 there :)
