For automated tests for your AEM UI, AEM provides the Bobcat testing framework. This framework, which provides a Javascript API for generating tests, allows you to write and run UI tests directly in a web browser. It also makes use of Hobbes.js, a Javascript-based testing package. The Hobbes.js framework was created as part of the development process for testing AEM and is now available for public usage for testing your AEM apps. It's an open-source test automation framework for web application functional testing.
