Answer questions for the graph defined by the following sets: ?

N = {1, 2, 3, 4, 5, 6} ?

N0 = {1} ?

Nf = {6} ?

E = {(1,2), (2,3), (3,4), (3,5), (4,5), (5,2), (2,6)} ?

def(1) = def(4) = use(3) = use(5) = use(6) = {x}

Test paths: ?

t1 = [1, 2, 3, 5, 2, 6] ?

t2 = [1, 2, 3, 4, 5, 2, 6]

a. Draw the graph.

b. List all of the du-paths with respect to x. (Note: Include all du-paths, even those that are subpaths of other du-path)

c. For each test, determine which du-paths that test path tours. For this part of the exercise, you should consider both direct touring and sidetrips.

d. List a minimal test set that satisfies all defs coverage with respect to x. (Direct tours only) Use the given test paths.

e. List a minimal test set that satisfies all uses coverage with respect to x. (Direct tours only) Use the given test paths.

f. List a minimal test set that satisfies all du-paths coverage with respect to x. (Direct tours only) Use the given test paths.
