Embedded functions in combinatorial testing: Progress in automating test design

Abstract:This talk introduces combinatorial testing (CT), from its origins in design of experiments to its present role in verifying interactions in complex systems. A persistent CT usability challenge has been the definition and enforcement of constraints among test factor values. Research progress in this area has enabled increased adoption among practicing software engineers. Recent work at led to the introduction of an embedded functions feature in its CT design service. The feature allows functionally dependent relations among test factors to be defined as functions in a general purpose programming language, PHP. These relations enforce constraints among test factor values and insure that all valid combinations of determinant factors are available for the test design. Resulting usability improvements enable automated pairwise test designs to meet novel objectives: Cover equivalence classes of expected results; verify univariate and multivariate equivalence class boundaries; verify corners among intersecting boundaries and edges.

Speaker Bio:

George Sherwood

George Sherwood is the founder and CEO of, which provides Software as a Service for combinatorial test designs. Earlier he worked at AT&T Bell Labs on a variety of hardware, software and service development projects. George has been actively involved in combinatorial testing since 1990, when he developed CATS at the Labs. This test case generator used a greedy search to accommodate system constraints. George has found innovative constructions for covering arrays and has devised search algorithms for He has degrees in physics, a Ph.D. from Yale University and a B.S. from Clemson University. George also serves on the board of the Princeton Joint Professional Chapter of the ACM and IEEE Computer Society.
