Question

What is the purpose of All-Uses coverage in dataflow analysis?

a.

To ensure that each definition of a variable is tested

b.

To ensure that each use of a definition is tested

c.

To ensure that each definition-clear path is cycle-free or a simple cycle

d.

To ensure that each definition-clear path is exercised

Posted under Software Engineering

Answer: (b).To ensure that each use of a definition is tested Explanation:The goal of All-Uses coverage is to construct tests that traverse a definition-clear path between each definition of a variable to each use of that definition and each successor of that use, in order to be sure that each possible use of a definition is being tested.
