A Test Automation Framework is a structured set of guidelines and tools designed to facilitate the automation of software testing. It provides a foundation for creating, executing, and maintaining automated test scripts, ensuring consistency and efficiency in the testing process. By using a framework, teams can improve collaboration and reduce the time needed for testing. These frameworks can vary in complexity and can include components like test libraries, reporting tools, and configuration management. Common types of frameworks include Keyword-Driven, Data-Driven, and Behavior-Driven Development (BDD) frameworks, each serving different testing needs and methodologies.
