Question 3

Given that Ce has n >= 0 elements, we say that T ____ Ce if for each element e’ in Ce there is at least one test case in T that tests e’

Answer 3

Covers

Question 4

T is considered ____ with respect to C if it covers all elements in the coverage domain

Answer 4

Adequate

Question 5

T is considered ____ with respect to C if it covers k elements of Ce where k < n

Answer 5

Inadequate

Question 6

The fraction k/n is known as the ____ of T with respect to C, P, and R

Answer 6

Coverage

Question 7

In case the program contains a loop, then it is adequate to traverse the loop body zero times and once

Answer 7

Modified Path Coverage Criterion

Question 8

An element of the coverage domain is ____ if it cannot be covered by any test in the input domain of the program under test

Answer 8

Infeasible

Question 9

T/F An algorithm exists that would analyze a given program and determine if a given element in the coverage domain is infeasible or not

Answer 9

F, no such algorithm exists

Question 10

T/F It is usually the tester who determines whether or not an element of the coverage domain is infeasible

Answer 10

T

Question 11

T/F Feasibility can be demonstrated by executing the
program under test against a test case and showing
that the element under consideration is covered

Answer 11

T

Question 12

T/F Infeasibility can be demonstrated by program

execution against a finite number of test cases

Answer 12

F, it cannot

Question 13

T/F An attempt to enhance a test set by executing a test t aimed at covering element e of program P may fail

Answer 13

T

Question 14

A ____ C is considered infeasible for predicate pr if there exists no input values for the variables in pr that satisfy C

Answer 14

Constraint

Question 15

T/F Infeasibility is the same as reachability

Answer 15

F

Question 16

In the presence of one or more infeasible elements in the coverage domain, a test is considered adequate when all ____ elements in the domain have been covered

Answer 16

Feasible

Question 17

Who is concerned with infeasible elements?

Answer 17

Testers

Question 18

T/F It is only during the attempt to construct a test case to cover an element that one may realize the infeasibility of an element

Answer 18

T

Question 19

T/F An adequate test set might will reveal even the most obvious error in a program

Answer 19

F, it might not
