“Hunting Bugs with a Shotgun and a Rifle” Published

Colts Neck, NJ, 25 July 2014 – The IEEE has published the proceedings of the The 3rd International Workshop on Combinatorial Testing, including Functional Dependence and Equivalence Class Factors in Combinatorial Test Designs. This paper is also known as “Hunting Bugs with a Shotgun and a Rifle” because it compares two approaches to combinatorial testing. The shotgun approach mixes the test factor combinations leading to different types of test results. The rifle approach focuses test cases on a single type of result (an equivalence class). Formulas to assess coverage of expected results are given in the paper. The author, George Sherwood, noted the formulas depend on relations among the test factors, not the generated test cases. So coverage can be assessed before, or without, generating the test cases.

“While the two approaches can be adopted as needed, there are significant differences,” Sherwood said. “The rifle approach directs test cases to each type of result, for efficient testing with fewer cases. But the expected results need to be known. When the system is not well specified, the shotgun approach may be required.” Slides presented at the workshop are available at the Testcover.com background page.
