Abstract

Algorithms for the construction of software interaction test suites have focussed on the special case of pairwise coverage; less is known about efficiently constructing test suites for higher strength coverage. The combinatorial growth of t-tuples associated with higher strength hinders the efficacy of interaction testing. Test suites are inherently large, so testers may not run entire test suites. To address these problems, we combine a simple greedy algorithmallwith heuristic search to construct and dispense one test at a time. Our algorithm attempts to maximize the number of t-tuples covered by the earliest tests so that if a tester only runs a partial test suite, they test as many t-tuples as possible.allHeuristic search is shown to provide effective methods for achieving such coverage.
