Test Optimization Using Combinatorial Test Design: Real-World Experience in Deployment of Combinatorial Testing at Scale

Abstract

Clients today want more for less and the IBM test mantra of Test Less Test Right helps address this ask by placing Combinatorial Test Design (CTD) at the heart of the solution. This document presents two case studies of CTD implementation in client engagements and focuses on the approach, process and challenges addressed to scale up the implementation and make CTD a mainstream activity. The IBM Focus tool was used in both cases to implement Combinatorial Test Design for optimization of tests and for reducing test effort while increasing test coverage.
