6.11 Application of Data Flow Testing

The Application of Data Flow testing and comparison with other testing techniques indicate following points:

  1. Sneed reported that the number of bugs detected by putting the criteria of 90% data coverage were capable to find defects those were twice as high as those detected by 90% branch coverage criteria.
  2. Weyuker reported that the mean number of test cases required per decisions to satisfy ACU, APU, AU and ADU are relatively small compared to branch coverage test. The number of test cases taken by ADUP is twice as many test cases as ACU or APU. Further studies have indicated that when AP is achieved it generally satisfied AC as well.
