Question: 1. Suppose that coverage criterion C 1 subsumes coverage criterion C 2. Further, suppose that test set T 1 satisfies C 1 on program P,

1. Suppose that coverage criterion C1 subsumes coverage criterion C2. Further, suppose that test set T 1 satisfies C1 on program P, and test set T2 satisfies C2, also on P.

(a) Does T1 necessarily satisfy C 2? Explain.

(b) Does T2 necessarily satisfy C1 ? Explain.

(c) If P contains a fault, and T2 reveals the fault, T1 does not necessarily also reveal the fault. Explain.2

2. How else could we compare test criteria besides subsumption?
