Appium - UI Automation for Apps

Appium is an open-source project and ecosystem of related software, designed to facilitate UI automation of many app platforms, including mobile (iOS, Android, Tizen), browser (Chrome, Firefox, Safari), desktop (macOS, Windows), TV (Roku, tvOS, Android TV, Samsung), and more.

Appium is used mostly in the field of software test automation, to help determine whether the functionality of a given app is working as expected. In contrast to other types of software testing, UI automation allows testers to write code that walks through user scenarios in the actual UI of an application, mimicking as closely as possible what happens in the real world while enabling the various benefits of automation, including speed, scale, and consistency.
