What is the main purpose of using a testing framework?

The main purpose of using a testing framework is to provide tools and methods that help automate and manage the testing process for software applications. This allows developers and testers to streamline their testing efforts, ensuring that they can efficiently run multiple tests, organize test scripts, and analyze results. By automating repetitive tests, a testing framework can improve productivity and accuracy, making it easier to identify bugs and verify that the software functions as intended.

Other choices focus on different aspects of software development. Ensuring compliance with coding standards is important for code quality but does not directly pertain to testing management. Designing user interfaces involves different tools and methodologies and does not relate to the testing process itself. Lastly, focusing solely on user experience testing is a narrow view and does not encompass the broader capabilities and objectives of a testing framework, which includes functional, performance, and regression testing among others.
