Published my first book titled "A Beginner's Guide To Android App Automation Using Appium"
Snippet from book:
Appium is an Open Source tool for testing native or hybrid mobile apps. It uses WebDriver JSON Wire protocol to drive both iOS and Android apps.There is descent documentation mentioned on the Appium site but somewhere it lacked to produce a guide, which can help you get rolling.This book is an effort to consolidate all the knowledge and resources to help you successfully use Appium to automate the android application. It will also help run the automated suite on real devices.
You can download the book and read it online here. Happy to welcome your feedback and reviews !
