Top Tools and Sample Code for Mobile App Compatibility Testing with Appium

When performing mobile app compatibility testing, you can use the following software and tools:

Appium – an open‑source automation testing tool for iOS and Android.

Calabash – an automation framework supporting iOS and Android, using Ruby.

Robot Framework – a generic automation framework supporting many applications and platforms, including mobile.

Selendroid – an automation framework for Android UI testing.

TestFlight – Apple’s platform for beta testing on iOS devices.

BrowserStack / App Live – cloud service for testing web and mobile apps on real devices and browsers.

Total Control – an automation tool for functional and compatibility testing of mobile apps.

Emulators – simulate real‑device environments, though they may differ in performance and hardware characteristics.

IETester – a free web‑browser control to simulate IE versions for web compatibility.

BrowserShots – a free cross‑browser testing tool that captures screenshots of sites in different browsers.

The following Python unittest script demonstrates a simple compatibility test with Appium, checking whether a specific element exists on different devices and OS versions.

import unittest
from appium import webdriver
from time import sleep

class CompatibilityTest(unittest.TestCase):
    def setUp(self):
        desired_caps = {}
        # Example for Android device
        desired_caps['platformName'] = 'Android'
        desired_caps['platformVersion'] = '10'
        desired_caps['deviceName'] = 'Android_device_name'
        desired_caps['appPackage'] = 'your_app_package'
        desired_caps['appActivity'] = 'your_app_activity'

        self.driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)

    def test_element_existence(self):
        sleep(5)
        try:
            element = self.driver.find_element_by_id('element_id')
            self.assertTrue(element.is_displayed(), "Element should be visible but is not")
        except:
            self.fail("Element not found")

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Adjust desired_caps with the actual device information, package name, activity name, and element ID for your app. More complex test cases and broader device coverage may be required for thorough compatibility testing.
