1. Acme Bank is developing a Car Loan Calculator mobile app to
help customers determine the monthly payment on a car loan.
The Car Loan Calculator has the following functional
requirements:
FR-01: The calculator allows the user to enter values for the
amount financed, the interest rate, and the term of the loan in
years.
FR-02: A valid entry for amount financed must be greater than
or equal to $1,000 and less than or equal to $100,000.
FR-03: A valid entry for interest rate must be greater than or
equal to 2.00% and less than or equal to 10.00%.
FR-04: A valid entry for the loan term must be three, four, five,
or six years.
FR-05: If all values entered are valid, the calculator computes
and displays the monthly payment amount for the loan, based on
the values entered by the user. The calculation uses the standard
fixed-rate loan amortization formula and assumes that payments
are made at the end of each month.
FR-06: If any value entered is not valid, the calculator displays
an error message indicating the invalid entry and the allowable
range of values for that entry.
FR-07: The calculator provides a link to the Acme Bank
website.
What are some test cases that would check whether the Car
Loan Calculator satisfies these requirements? Describe a test
case, including the steps to be performed, the expected results,
and listing the requirement(s) being tested.
