Appium

Appium is an open-source tool designed for automating mobile applications on both Android and iOS platforms. It allows developers and testers to write tests for their apps in various programming languages without needing to modify the app's source code. By simulating user interactions, such as tapping and swiping, Appium helps ensure that apps function correctly before they're released. Its versatility and support for multiple languages make it a popular choice for quality assurance in mobile app development, enabling teams to identify and fix issues efficiently.
