Mobile Application Testing with Selenium and Python by Jason Carr

Selenium has grown to be a mature platform on the desktop, but with 'mobile now' being the mantra for so many companies, can we use Selenium to effectively test mobile apps? What about Native apps? This talk will cover using Python to test mobile web applications with Selenium, as well as an in depth overview of the future of Selenium to test Native iOS and Android applications.

3. Very brief aside: I woke up this morning…
5. PyCon is an amazing community of very kind and helpful people. Thank you Augie Fackler, Jonathan Lipps, and Terry Peppers.
6. 1 What is Selenium? 4 3 2
7. Selenium is an Open Source library for automating browsers.
8. The goal is coverage for every browser on every platform.
9. Selenium RC AKA ‘Selenium 1’ Uses javascript injection to drive browsers Has no mobile implementations Don’t use this.
10. Selenium WebDriver AKA ‘Selenium 2’ Uses native OS events to drive browsers Has iOS and Android drivers Use this!
11. How WebDriver Works
12. Example Test from selenium import webdriver driver = webdriver.Firefox() driver.implicitly_wait(30) driver.get('http://us.pycon.org’) driver.quit()
13. Demo
14. 1 Let’s get mobile. 4 3 2
15. Same Test. Different Browser.
16. Tricky.
17. Example Test from selenium import webdriver driver = webdriver.Firefox() driver.implicitly_wait(30) driver.get('http://us.pycon.org’) driver.quit()
18. Example Test from selenium import webdriver desired_capabilities = {} desired_capabilities['browser'] = 'iphone’ desired_capabilities['platform'] = 'MAC’ desired_capabilities['version'] = '6.1’ driver = webdriver.Remote( 'http://localhost:3001/wd/hub', desired_capabilities) …  
19. Example Test from selenium import webdriver desired_capabilities = {} desired_capabilities['browser'] = ’android’ desired_capabilities['platform'] = ’Linux’ desired_capabilities['version'] = ’4.2’ driver = webdriver.Remote( 'http://localhost:8080/wd/hub', desired_capabilities) …  
20. iOS WebDriver Requires Xcode and a Mac A .app that you run in the simulator Some big limitations (alerts, frames, quit) Build app locally and point your tests at it
21. Demo
22. Android WebDriver Requires Android SDK A .apk that you run in the emulator Setup is hard. Really annoying. Supports 2.3.x and later Emulator is slow.
23. Android WebDriver Setup Install Android SDK Create AVD Launch AVD Use ADB to connect to device, start app, and forward ports.
24. Demo
25. Limitations ‘WebViews’ Not a real browser Second class citizens Hard to accurately test Hard to use on real devices Each mobile implementation is different
26. 1 Native apps 4 3 2
27. iOS
28. Problems UI Automation - Javascript only - Very limited set of commands - Limited command line control - No interaction with tests No Test Interoperability
29. Android
30. Problems UI Automator - Java tests, compiled and pushed - No interaction with tests No Test Interoperability
31. Alternatives - Require recompiling app to add code - Various APIs - Mixed community & limited help - Forced language implementation
32. Test Reuse
33. The Solution is Appium
34. Appium - No recompilation of app - Uses Selenium API - All methods are rst class citizens - Any language, any OS, any framework - Open Source
35. Appium for iOS - Wraps UIAutomation and Instruments
36. Demo h8p://evr.st/  
37. Appium for Android - Wraps UI Automator Android! UI Automator!

39. 1 Driving the Browser 4 3 2
40. Work in Progress
41. Why Automate Mobile Browsers? - Drive a real browser - Actual rendering - Accurate - Works on real devices - Standards driven (atoms, W3C)
42. Demo
