DESCRIPTION:This talk reports the results of a study comparing the effecti
 veness of automatically generated tests constructed using random and t-way
  combinatorial techniques on safety related industrial code using mutation
  adequacy as the acceptance metric. A reference point to current best prac
 tice is provided by using hand generated test vectors constructed during d
 evelopment to establish minimum acceptance criteria. The study shows that 
 2-way adequate test sets are not adequate as measured by the mutants kill 
 rate compared with hand generated test sets of similar size\, but that hig
 her factor t-way test sets can perform at least as well. To reduce the com
 putation overhead of testing large numbers of vectors over large numbers o
 f mutants a staged optimising approach to applying t-way tests is proposed
  and evaluated which shows improvements in execution time and final test s
 et size.
