# 1. Goal
Calculate the price of a hotel stay. A booking program calls the calculation
before it shows the price to the guest. The program needs one reason code for
each invalid input.
# 2. Open questions
None.
# 3. Context
- The interface {{P}}IF_HOTEL_RATE exists in package $TMP. It is active.
- The interface has these types:
- TY_CATEGORY: character, length 1.
- TY_REASON: character, length 10.
- TY_AMOUNT: packed number, length 10, 2 decimals.
- TY_RESULT: structure with the components REASON (TY_REASON) and
PRICE (TY_AMOUNT).
- The interface has these constants:
- C_REASON: OK, NIGHTS, GUESTS, CATEGORY.
- C_CATEGORY: BASIC 'S', COMFORT 'C', SUITE 'U'.
- The interface has one method:
CALCULATE
IMPORTING iv_category TYPE ty_category
iv_nights TYPE i
iv_guests TYPE i
iv_breakfast TYPE abap_bool
RETURNING VALUE(rs_result) TYPE ty_result.
# 4. Contract
- Create the class {{P}}HOTEL_RATE in package $TMP.
- The class is public, final, and has a public constructor without parameters.
- The class implements {{P}}IF_HOTEL_RATE.
- Do not add other public methods.
# 5. Business rules
Check the input in this sequence. Return the reason of the first check that
fails and the price 0.
1. If IV_NIGHTS is less than 1, return NIGHTS.
2. If IV_GUESTS is less than 1, return GUESTS.
3. If IV_CATEGORY is not BASIC, COMFORT or SUITE, return CATEGORY.
4. Else return OK and calculate the price.
Calculate the price in this sequence:
1. One room takes at most 2 guests. The number of rooms is the number of guests
divided by 2, rounded up.
2. The price of one room for one night is 90.00 for BASIC, 140.00 for COMFORT
and 260.00 for SUITE.
3. The room total is the number of rooms multiplied by the number of nights
multiplied by the price of one room for one night.
4. Long stay discount on the room total:
- 28 nights or more: 20 %
- 14 nights or more: 15 %
- 7 nights or more: 10 %
- less than 7 nights: no discount
The discounted room total is the room total minus the discount.
5. Breakfast costs 12.50 for one guest for one night. Add it if IV_BREAKFAST is
true.
6. City tax costs 3.00 for one guest for one night. Add it always.
7. The price is the discounted room total plus breakfast plus city tax.
All amounts are exact to two decimals.
# 6. Constraints
- Release target: 8.16.
- Coding standards: Clean ABAP. Method length below 40 statements. No global
variables. No comment that restates the code.
- Out of scope: do not change {{P}}IF_HOTEL_RATE.
# 7. Acceptance
- The class is active and has no syntax error.
- The hidden tests pass.
- Write your own ABAP Unit tests for the class.
