Comparing Cause-Effect Graphing Test Case Coverage to Manual Test Case Coverage

Gary Mogyorodi

APRIL MEETING
Tuesday, April 29, 2008

Main Message:

A rare opportunity to compare two test case design techniques on the same problem, showing how much better test case coverage can be with a rigorous approach.

Presentation Description:

The Requirements-Based Testing (RBT) methodology uses the Cause-Effect Graphing technique for test case design. In a Proof-of-Concept engagement at an insurance company, I had the rare opportunity to compare the test coverage using the Cause-Effect Graphing technique to the set of manual test cases already created for the same problem.

Outline:
The presentation will focus on:

1. An Overview of Requirements-Based Testing and its components:

- Ambiguity Reviews - Cause-Effect Graphing test case design technique

2. A description of the problem for which the test cases were created

3. A comparison of the test case coverage provided by the Cause-Effect Graphing test cases compared to the manual test cases for the same problem

Bullet Points:

• Overview of Requirements-Based Testing
• Overview of Ambiguity Reviews
• Overview of Cause-Effect Graphing
• A description of the software problem that was addressed
• Test Coverage Measures
