The purpose of a test automation framework is to provide a structured environment that facilitates automated testing of software applications. This framework includes guidelines, standards, tools, and processes to streamline the testing process, improving efficiency and consistency in test execution. Test automation frameworks aid in reducing manual effort, allowing testers to focus on higher-level tasks. By promoting reusability and maintainability of test scripts, they help ensure software quality and reliability in the long term. Overall, these frameworks are essential in modern software development practices.
