3. You are given a code-under-test, Converter; two sets of test cases generated using two different techniques which are Technique A and Technique B; and two mutants. Analyse the given information using mutation testing analysis and determine which technique is the most effective one. For the technique that less effective, generate additional test case to enhance the effectiveness. 1 public void Converter (int num) { if (num <100 && num>=1) { 2 3 System.out.println("A two digit number"); } else if (num <1000 && num>=100) { System.out.println("A three digit number"); } else if (num <10000 & & num>=1000) { Suctom out println(" four digit numbor"): 4 567 00 0

Transcribed Image Text:3. You are given a code-under-test, Converter; two sets of test cases generated using two
different techniques which are Technique A and Technique B; and two mutants. Analyse
the given information using mutation testing analysis and determine which technique is the
most effective one. For the technique that less effective, generate additional test case to
enhance the effectiveness.
