What is the role of test prioritization in software testing?

The role of test prioritization in software testing is to determine the order in which tests should be executed based on their importance and potential impact on the system. It helps in optimizing the testing process by focusing on critical areas or functionalities first, ensuring that high-risk areas are thoroughly tested and any critical defects are identified and fixed early in the development cycle. Test prioritization also helps in managing time and resources effectively by allocating them to the most important and impactful tests, ultimately improving the overall quality of the software.
