What is a use case?

 A use case describes how a user interacts with a system to achieve a specific goal. It outlines the steps, inputs, and expected system behaviour based on user actions.

Use cases help define application workflows and user journeys. They do not have pass-or-fail criteria, but they do establish a happy path, which represents the ideal, error-free execution of a process. They are required for understanding user flow and designing test scenarios.
