Android App Testing Services is in great demand and is considered as one of the important testing practice, as day by day, we see drastic growth in mobile app development, i.e. each day, lots of mobile apps are developed, which could be for Android or iOS. Mobile test automation provides various test solutions, which help you to verify and validate the overall functioning of the mobile apps.
Some of the most useful and preferred testing frameworks/tools for Android app automation testing are:
1. Appium: It is a open source test automation framework for mobile web apps.
2. TestingWhiz: TestingWhiz allows you to automate mobile web testing for Android and iOS on a variety of browsers, operating systems and emulators. It is powered by Appium, which lets you automate tests of any native and hybrid mobile apps from UI level down to the complete back-end and functional-level testing on real devices and simulators.
3. Robotium: This is a test automation tool, used for Android development.
Among these tools, I would like to suggest you to use TestingWhiz, as it has the integration of Appium, which will indirectly help you to have a brief knowledge of these tools. Also this tool is one of the most user-friendly and easy to learn test automation tool, because of its code-less scripting feature.
