SOFTWARE VERIFICATION & TESTING HOMEWORK ASSIGNMENT 4 [40 POINTS] [Q] [40 points] Use the program listing below to answer the questions that follow. Note that this is not a working program. The intent of the assignment is for you to apply your knowledge of structural testing to answer the accompanying testing questions. 1. public static void main(String[] args) { 2. double a1 = 1.0; 3. double a2 = 2.0; 4. double a3 = 3.0; 5. if (cl) { 6. r1 = rate * 1.1; 7. r2 = rate * 2.1; 8. } else { 9. r3 = rate * 3.1; 10. r4 = rate * 4.1;} 11. while (c2) { 12. a5 = r1 * r3; 13. a6 = r2 * r4; 14. switch (c3) { 15. case 'A1': 16. a7 = a1 + a5; 17. a8 = a3 * a2; 18. break; // End Case A1 19. case 'A2': 20. s1 = a5 + a6 ; 21. s2 = s1 * a3; 22. if (c4) { 23. s3 = s2 * 1.5; 24. s4 = s2 * 2.0; 25. } else { 26. s3 = s2 * s1; 27. s4 = s2 * s2;} 28. break; // End Case A2 29. case 'A3': 30. s5 = a6 + a5 * a1; 31. s6 = a6 + * (a1 / a2); 32. break; // End Case A3 33. default: 34. System.out.println("Invalid"); 35. } // End Switch 36. t1 = s3 * s4; 37. t2 = s3 * s5; 38. t3 = s4 * s6; 39. if (c5) { 40. t4 = t3 * 9.99;} 41. t5 = t1 + t2 ; 42. } // End While 43. System.out.println("Computation complete!"); 44. } (a) Use structured programming constructs to draw the program graph (b) Compute the cyclomatic complexity (c) Determine a set of basis paths through the graph (d) Create the test cases that will exercise the basis paths by determining the values of the conditions at each
