Consider the above graph

List the test requirements for node coverage and edge coverage

List test paths that achieve node coverage but not edge coverage on the graph

List the test requirements for edge$-$pair coverage.

Consider the following set of test paths

$t0=[1,3,4,7,6,1,5]$

$t1=[1,3,2,3,4,6,1,5]$

Does the given set of test paths satisfy edge$-$pair coverage? If not, identify what is missing

Consider the simple path $2,3,4,7,6$ and test path $1,3,2,3,4,6,1,2,4,7,6,1,5.$ Does the test path tour the simple path directly? With a sidetrip? If so$,$ identify the sidetrip.
