Appium
I promise to be awesome!

Appium
• Open source
• Selenium for mobile
• Client/Server architecture
• JSON wire protocol
• One device at a time with one server (present)
• Yes selenium grid for parallel testing
• Six language clients

Parallel Tests
It is so fast!

Design principles :
• Atomic: small and concise
• Independent
• Organized
• Configurable

Selenium Grid :
• Another web server - Hub
• Manages other webdrivers
• Manages appium servers
• Responsible for distributing
tests
• Appium server is here - Node

Steps for grid setup:
• Download Selenium-standalone.jar
j java -jar selenium-server-standalone-2.48.2.jar -role hub
ava -jar selenium-server-standalone-2.48.2.jar -role hub
• Start it with role as hub
• Start multiple emulators or devices (iOS limitation)

Steps for grid setup: Appium
• Currently appium can only handle one session at a time
• Start multiple appium sessions with different port
• Define configuration file to rester session with hub
• Register session with hub using —nodeconfig.json
• https://github.com/appium/appium/blob/master/docs/en/advanced-
concepts/grid.md
• example
https://github.com/moizjv/appium/blob/appium_meetup/android1.json
node . --port 4000 --nodeconfig ./android1.json -U emulator-5554 -bp 2252
node . --port 4000 --nodeconfig ./android1.json -U emulator-5554 -bp 2252

Running parallel tests
• Configure tests to run in parallel
• Point test to hub as remote driver
• Set capabilities to match registered remote driver
• Run the tests!!!

Demo
Live demos are dangerous!

Conclusion
• Parallel tests should be written to scale
• Presently iOS has limitation one simulator at a time
• Parallel testing strategy if done right can speed up testing
process significantly
