Order numbers on a stock control system can range between 10000 and 99999 inclusive. Which of the following inputs might be a result of designing tests for only valid equivalence classes and valid boundaries:
A. 1000, 5000, 99999
B. 9999, 50000, 100000
C. 10000, 50000, 99999
D. 10000, 99999
E. 9999, 10000, 50000, 99999, 10000
10)
In a flight reservation system, the number of available seats in each plane model is an input. A plane may have any positive number of available seats, up to the given capacity of the plane. Using Boundary Value analysis, a list of available – seat values were generated. Which of the following lists is correct?
a. 1, 2, capacity -1, capacity, capacity plus 1
b. 0, 1, capacity, capacity plus 1
c. 0, 1, 2, capacity plus 1, a very large number
d. 0, 1, 10, 100, capacity, capacity plus one
11) Why does the boundary value analysis provide good test cases?
a. Because it is an industry standard
b. Because errors are frequently made during programming of the different cases near the ‘edges’ of the range of values
c. Because only equivalence classes that are equal from a functional point of view are considered in the test cases
d. Because the test object is tested under maximal load up to its performance limits
