- 5. March 2018 How does selenium do its web magic? How does selenium find a web element How does it get an attribute How does it click on the web element? No not “protons, neutrons, and electrons”, but javascript scripts called atoms. NOTE: not every action requires atoms (e.g. navigate)
- 6. March 2018 How do atoms work? Find Element example: (<find-element-atom.js>)("id", "element-id") response: "{"status":0,"value":{"ELEMENT":":wdc:1518519286442"}}" storage: document.$wdc_
- 7. March 2018 How do atoms work (continued)? click example: (<click-element-atom.js>)({"ELEMENT":":wdc:1518520215151"}) get-attribute example: (<get-attribute.js>)({"ELEMENT":":wdc:1518520215152"}, "<attribute-name>")) Lets see them in action.
- 8. March 2018 So how do we execute the atoms? How does Appium send the atoms to the browser and how does it retrieve the response? Remote Debugging Protocols! It obviously can’t CTRL+C, CTRL+V like I just did.
- 9. March 2018 Remote debugging { method: 'Runtime.evaluate', params: { expression: 'return document.title' returnByValue: true } }; Execute JavaScript example:
- 10. March 2018 Remote debugging (continued) { method: 'Page.navigate', params: { url: 'http://www.saucecon.com' } }; Navigation example:
- 11. March 2018 Historical Appium challenges (in 2013) • Unable to run web tests on Safari on physical devices • No/little support for remote debugging on mobile browsers • No easy access to browsers on physical devices • No ability to launch/close Safari on iOS devices • Not all features were (yet) covered by Appium • API was not fully defined (and constantly changing) • No appium Java client. Back in the day everything used to be better … uhh, well no.
- 12. March 2018 Challenge: Safari on a physical device My question (April 2013): “I am trying to grab the window_handles on the WebViewApp and this is working fine on a iPhone simulator, however it's throwing an unhandled exception on a real device” ios-webkit-debug-proxy: Luckily someone had already figured a way to forward requests to a physical device and we just connected the dots (Appium - Pull Request 562 – for a laugh ). Jonathan Lipps: “This is unfortunately expected. Webview support works by creating a TCP connection to the remote webkit debugger run in Safari/webviews. Even though the real device might be running a webkit debugger, it's almost definitely not forwarding that port to the host, where appium is running. Someone will need to figure out how to reverse engineer the USB debugging protocol and forward the port from the device to the host--- sounds like it will be challenging at best and maybe impossible at worst.”
- 13. March 2018 Challenge: Launching safari on a deviceCan we use Instruments? Can we use remote debugging? Safari Launcher app ● Just navigate to a url and forces iOS to open Safari ● Add “--real-safari” argument when running reset.sh (build safari launcher with default profile) ● To build & install safari you will need a valid development profile Can we use … an app?
- 14. March 2018 Challenge: Closing tabs on safari Can we use javascript? Can we use remote debugging? Can we use Instruments? Or can they ? window.open('','_self').close();
- 15. March 2018 iOS (before iOS 9.3) - DEPRECATED
- 16. March 2018 iOS XCUITest (iOS 9.3 +)
- 17. March 2018 WebInspector vs WebKit protocol WebInspector protocol wraps the Webkit protocol messages in an “envelope” and adds additional fields (such as ApplicationIdenitifier, PageIdentifier, SenderKey, ConnectionIdentier). So if we use the Runtime.evaluate example, these fields will tell the web inspector, which app and page it should execute the script on.
- 18. March 2018 iOS Web Testing - Pull Request?
- 20. March 2018 Chrome://inspect So how does chrome inspect do it? The same way as appium
- 21. March 2018 Android (Selendroid) - DEPRECATED
- 22. March 2018 Additional endpoints Mobile JSON wire Protocol (DRAFT): • Touch Actions (Tap, Swipe, Pinch) WebDriver Protocol Extensions: • Install/Uninstall App, Launch/Close app • Get Performance Data (Android) • CPUInfo • MemInfo There are many more.

- 24. March 2018 Future of mobile web testing? • Network.clearBrowserCache (CDP 1.2) • Browser.close & Browser.getVersion (CDP 1.3) • Log.entryAdded (CDP 1.3) • Synthesize Tap/Pinch (CDP TOT) • Network.requestIntercepted (CDP TOT)
