Combinatorial Test Design – A Smarter Way to Connect with the Business
Saritha Route, Sudheer Pendela · 2018
A formal quality gate called the Test Readiness Review (TRR) is a typical pre-requisite for commencing System Integration Testing. For a large program that is currently underway, we were in the test design phase. There were continued delays in the Test Readiness sign off from the client. The main reason was the 300 plus open questions related to requirements clarity that was impacting the test preparation completion. To address this impasse, we introduced Combinatorial Test (CT). The aim was to provide coverage assurance and uncover gaps in tests and requirements using CT. The interactive CT design process would ensure that open questions, undocumented requirements and system interactions are highlighted using scientific methods without bias. Thus, aiding speedy closure of gaps in both requirements and test cases. We used the IBM IGNITE Method for deploying Combinatorial Test Design, which engages stakeholders and implements CT techniques with the Focus tool.
