48 Use Cases and Testing: Using Use Cases to Write Test Cases

Jim Heumann
Rational Software, jheumann@rational.com

Use cases, a proven technique for specifying functional requirements, are particularly powerful because of their ability to be easily used by other members of the software development team. This is true in testing, where requirements form the basis for determining whether system objectives and quality measures have been met. The ability to create test cases from, and trace them to, use cases is a vital skill for ensuring a quality product. This tutorial will introduce a straightforward technique, based on the Rational Unified Process, for generating test cases directly from use cases. The tutorial will start with a brief introduction to use cases including guidelines for content and format to facilitate testing, and will continue by explaining the three key steps used for generating test cases: finding use case scenarios, identifying conditions and data elements to test, and adding data values for testing.

Attendee background

A familiarity with use cases would be helpful, but not required.

Format

Lecture/presentation interspersed with discussion of the examples and an in-class exercise.
