A money order system is designed to calculate the

charge for a transfer.

- Amounts from 1 to 1999 are charged EUR 10.

- Amounts from 2000 to 5000 are charged EUR 15.

- Amounts below EUR 1 or above EUR 5000 are not

accepted. Assume that only integer values can occur.

Which of these sets of amounts covers all equivalence

classes?

Select one:

a. 0, 99-1-2000-4999, 99

b. 0-1999-2000-5000

c. 0-100-2000-6000

d. 1-2000-5001-10000

The question has 4 classes ( Less than 1, EUR 10, EUR

15, More than 5000), so check for data in all these class.

First Class (Less than 1) should have value less than 1

like 0, - ve integer

Second Class (EUR 10) should have value anything from 1

to 1999

Third Class (EUR 15) should have value from 2000 to 5000

Fourth Class ( More than 5000) should have value more

than or equal to 5001

The correct answer is: 0-100-2000-6000

to re-run a complete section of the tests. Which of the

following is correct?

Select one:

a. The test engineer should not re-run the tests; they

should be part of the developer tests
