What effect does high priority have on test case execution?

High priority in test case execution signifies that certain tests are critical to the project and must be conducted early in the testing process. This prioritization often aligns with business requirements, customer needs, or critical functionalities that are essential for project success. By ensuring that important tests are run early, the team can identify and address significant issues before they escalate, helping to mitigate risks, save time, and optimize resource allocation.

When high priority tests are executed first, it also allows for more efficient use of the testing phase, ensuring that core functionalities are validated quickly, which is instrumental in maintaining project timelines and enhancing the overall quality of the product. Hence, focusing on high-priority test cases is a strategic approach that facilitates effective risk management in software development.
