Given below is an example of executing code for the testing in Python language


desired_capabilities = {

    ‘platformName’: ‘Android’,

    ‘deviceName’: ‘your_device_name’,

    ‘app’: ‘path/to/your/app.apk’,

    ‘automationName’: ‘UiAutomator2’,  # Use UiAutomator2 for Android

    ‘autoGrantPermissions’: True



driver = webdriver.Remote(‘http://localhost:4723/wd/hub’, desired_capabilities)


# Perform actions and retrieve accessibility information

element = driver.find_element_by_id(“your_element_id”)

content_description = element.get_attribute(“contentDescription”)

from appium import webdriver

from axe_selenium_python import Axe


# Set up Appium driver

driver = webdriver.Remote(‘http://localhost:4723/wd/hub’, desired_capabilities)


# Run axe accessibility checks

axe = Axe(driver)

results =


# Analyze results and take appropriate actions

Run the Appium test script 

Run your Appium test script locally or through a cloud testing platform. Check that the target device or emulator is operational and correctly configured. Running the script starts the automated testing process, which includes the execution of accessibility tests.


# Run your Appium script


Analyze accessibility test results.
