Software Testing

(4) Random vs Partition-Based Testing

What is the idea of Gutjahr's Model?

  • Failure rate becomes random variable whose value can be obtained from statistics
  • Replace deterministic numbers of failure-causing inputs with random variables
    • Consider expected values instead of failure rates
  • Tester can never say: "The program currently to be tested has, with certainty, a failure rate of 2%"
