Abstract

Dynamic test sequence compaction is an effectivemeans of reducing test application time and often results in higher fault coverages and reduced test generation time as well. A new algorithm for dynamic testsequence compaction is presented that uses genetic techniques to evolve test sequences. Test sequences providedby a test generator and previously evolved sequences already included in the test set are used as seeds in thegenetic population. Significant improvements in test setsize, fault coverage, and test generation time have beenobtained over previous approaches.
