48 Guided Inspection of UML Models

Wednesday, 29 October – 13:30-17:00 Afternoon

John McGregor, Clemson University, johnmc@cs.clemson.edu

There is widespread agreement that finding defects as early in the development life cycle as possible is cost effective; however, there are few systematic techniques for accomplishing this goal. Guided inspection is an inspection technique that is "guided" by test cases. By constructing a "complete" set of test cases, the guided inspection technique identifies elements missing from the model, and it also evaluates the quality of those that are present. This tutorial illustrates the technique using design models created using the Unified Modeling Language. Checklists designed for use at various points in a typical development process assist the inspector in selecting the most effective test cases.

Guided Inspection has several benefits:

  • Objectivity - systematically selects test cases to give all portions of the model equal coverage.
  • Traceability - links the faults detected back to specific requirements.
  • Testability - identifies portions of the design that are complex and require much effort to test.

After taking this tutorial, participants will be able to:

  • define test scenarios from use cases.
  • apply these test cases to an actual system model.
  • adapt the technique and checklists to the maturity of a specific model.

Attendee background

Prerequisites: Attendees should be familiar with UML. It will be helpful if attendees have participated in software reviews and inspections previously.
