Appium Inspector is a tool integrated into Appium Desktop, which combines the Appium Server and Inspector to facilitate mobile app testing by identifying unique UI elements of applications under test. It supports Android and iOS devices and is designed to streamline the automation of new apps by enabling script recording and element discovery. Users can download and install Appium Inspector on both Windows and OS X platforms to gain insights into app element hierarchies, attributes, and conduct manual app action recordings. Despite its benefits, such as allowing remote device access and supporting hybrid apps, Appium Inspector has limitations, including lack of support for older Android versions and some hybrid app actions. Cloud-based platforms like LambdaTest enhance Appium Inspector's functionality by offering real device testing, integration capabilities, and a user-friendly interface, which simplifies the testing process and reduces the dependency on setting up Appium Desktop on-site.
