3. (30 points) Graph Coverage Criteria Consider the following control graph: a. Find the test requirement(TR) and Test Paths for Node Coverage (NC). b. Find the test requirement(TR) and Test Paths for Edge Coverage (EC). c. Find the test requirement(TR) and Test Paths for Edge-Pair Coverage (EPC). d. Find the test requirement(TR) and Test Paths for Prime Path Coverage (PPC). e. Compute the coverage level for the test requirements generated in parts b and e using the test set T={[A,F],[A,B,C,B,F]}. f. From your answer to part b, do you expect the test requirement, TR, for EdgePair Coverage to be equivalent to the Prime Path Coverage for this graph or not. Justify your
