Test Design: Developing Test Cases from Use Cases
By Ross Collard
  
Summary:
A use case is a sequence of actions performed by a system, which combined together produce a result of value to a system user. Use cases describe the "process flows" through a system based on its actual likely use, so the test cases derived from use cases are most useful in uncovering defects in the process flows during real-world use of the system. Here is an example of how a use case is used to derive and prioritize test cases.
