EP & Boundary Questions
Suppose you have a bank account that offers
variable interest rates:
5% for the first $1000 credit;
10% for the next $1000;
And 15% for the rest.
If you wanted to check that the bank was
handling your account correctly what valid
input partitions might you use?
EP & Boundary Questions
A mail order company charges $2.95 postage
for deliveries if the package weighs less than 2
kg, $3.95 if the package weighs 2 kg or more
but less than 5 kg, and $5 for packages
weighing 5 kg or more.
Generate a set of valid test cases using
equivalence partitioning.

above; and distinction at 80 and above.
Determine the boundary values

In a system designed to work out the tax to be paid:
An employee has £4000 of salary tax free. The next £1500 is
taxed at 10%
The next £28000 is taxed at 22%

Boundary Value Analysis test case?
a)
b)
c)
d)
£1500
£32001
£33501
£28000
Equivalence & Boundary Value based questions

partitions?
a. 10,11,21
b. 3,20,21
c. 3,10,22
d. 10,21,22
