Appium vs Espresso for automated testing framework
- The Shifting will be very much useful as Espresso supports testing activities outside the app like camera, browser and dialer etc which appium does not support.
- Espresso you can test toast message, auto complete and dialogs which are outside app.
- With Espresso Test Suit you can find code coverage and measure your testing efforts.
You can go to Espresso if you're sticking only to Android automation and have no idea of automating iOS.
AFIKW, Espresso needs source code of the app in order to automate it.
Advantage is, it's directly open-sourced by google.
But my go is to go with Appium since its a large open sourced community with huge enhancements on its way and easy to automate with any programming language and needless to say it supports both Android and iOS.
