Appium is an open-source framework for testing web apps. It can be used with native, hybrid, and mobile web apps. It can drive iOS, Android, or Windows apps using the WebDriver protocol. Appium was created with the idea that native apps should not require recompiling or including an SDK. Appium should allow you to use your preferred frameworks, test practices, and tools. Appium is an open-source project. We have made design and tool choices to encourage a vibrant contributor community. Appium is designed to automate mobile apps from any language and any testing framework. It also allows full access to back-end APIs, DBs, and test code. You can write tests using your favorite development tools, including all the languages mentioned above and possibly more (with the Selenium WebDriver and language-specific client library).
