Defect Prevention and Test Design Optimization Together — CDT


The key to testing is to create the best test case for a given application. Test case creation and implementation is both costly and time consuming, meaning that typically the goal is to optimize this process by planning a moderate-sized and efficient test set which reveals most of the bugs.

However, testing itself is not enough: according to a huge amount of collected data published by Capers Jones in 2012, on average only about 85% of bugs are found in the testing stage. Defect prevention in IT is as important as disease prevention in healthcare.

Constraint Driven Testing (CDT)

Our method originates from category-partitioning, published by Thomas J. Ostrand and Marc J. Balcer in 1988. We have sought to establish a widely applicable test design method…
