Embedded Functions for Test Design Automation

Abstract

Testcover.com introduced an embedded functions feature into its combinatorial test 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 considered 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. The demonstration illustrates how embedded functions can improve automation, accuracy, control and flexibility in the test design process.
