AppiumI 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• https://github.com/saucelabs-test-frameworks/

Selenium Grid :

• Another web server - Hub• Manages other webdrivers• Manages appium servers • Responsible for distributing

tests• Appium server is here - Node

© Sauce Labs, Inc.

Steps for grid setup:

• Download Selenium-standalone.jar

j java -jar selenium-server-standalone-2.48.2.jar -role hubava -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/adva

nced-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
