ABSTRACT
Since it is nearly always impossible to test all possible combinations, combinatorial testing is a reasonable alternative. But it is not always practical to redesign an organization’s testing procedures to use tests based on covering arrays. Testing procedures oen develop over time, and employees have extensive experience with a particular approach. Units of the organization may even be structured around established, documented test procedures. is is particularly true in organizations that must test according to contractual requirements, or regulatory standards. And because much soware assurance involves testing applications that have been modied to meet new specications, an extensive library of legacy tests will exist. e organization can save time and money by reusing existing tests, which generally have not been developed as covering arrays.
