Question

Testing a function or program using test values that are at or near the values that change the outcome of the program is known as using:
a. parameters.
b. a black-box.
c. boundary values.
d. functional decomposition.

Answer 1

Answer:

c. boundary values.

Explanation:

boundary values are used when checking a range of values, after selecting the set of data that lie in the valid partitions, next is to check how the program behaves at the boundary values of the valid partitions.

e.g. if I have an input field that accepts values from 10 to 100 then 10 would be the minimum, 100 would be the maximum.
