5. Consider a test suite that exercises all the following paths through the Control Flow Graph (CFG) shown in Figure 2: (1, 2, 3, 9, 2, 10, 11, 13), (1, 2, 10, 11, 13), (1, 2, 3, 9, 2, 3,9, 2, 10, 11, 13) 10 3 11 12 13 Figure 2. A control flow graph Calculate the following test coverages for the test suite: (i) Branch coverage (ii) Basis path coverage (10 marks) 6. Consider the CFG shown in Figure 2. Do the following: (i) Identify a minimal set of paths through the CFG that pass through all the branches at least once. (ii) Calculate the total number of paths through the CFG that pass through the loop exactly 4 times. (10 marks)
