Appium is an open source, cross-platform automation testing tool. It is used for automating test cases for native, hybrid and web applications. The tool has a major focus on both Android and iOS apps and was only restricted to the mobile application testing domain. Recently, a few updates back, Appium also announced that they will support the testing of desktop applications for windows. Appium is developed and maintained by Sauce Labs. Currently, Appium version 1.10 is being distributed. Appium first started off as a command line based testing service that can be installed using Node.js. In their latest release, named ‘Appium desktop’ they have released a robust and refined tool with an intuitive graphical user interface.
