Question

 What would we learn from Robust Normal Boundary Value test cases for the 
Quadrilateral Program? The values are:
c1. 0 ≤ a ≤ 201 (top)
c2. 0 ≤ b ≤ 201 (left side)
c3. 0 ≤ c ≤ 201 (bottom)
c4. 0 ≤ d ≤ 201 (right side)

Expert Solution
Step 1

Answer:

Generate boundary Value analysis, robust and worst-case test case for the program to find the median of three numbers. Its input is a triple of positive integers (say x, y, and z) and the minimum value can be 100 and maximum can be 500.

Median of three numbers is the middle number when all three numbers are sorted.

Example – 10,40,20

 

In this case, the median is 20 (10, 20, 40).

1. Boundary Value Test Cases are –

for x, y, z:

min value = 100

close to min = 101

nominal = 300

close to max = 499

max = 500

Test cases are,

4*3 + 1 = 13
