Is a Use Case a Test Case?

This presentation draws the following conclusions:

• Use cases are extremely effective for specifying
  functional requirements
• Use cases unify the requirements, design, and testing
  strategies
• Each use case is a pattern for a test case and its
  associated test procedures
• Testing based on use cases provides primary functional
  test coverage
• Unit testing of use case realizations, both static and
  dynamic aspects, provides additional levels of quality
  assurance
