# 1. Goal
|
|
Fix the class {{P}}LAUNDRY_PRICER. A laundry service uses the class to calculate the price of a laundry order. Users report three defects:
|
|
- A member pays the wrong price for a small order.
|
|
- A member gets a discount on the express surcharge.
|
|
- Ironing is much too expensive.
|
|
The class must calculate the correct price for every order.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The class {{P}}LAUNDRY_PRICER exists in package $TMP. It is active.
|
|
- The class is public and final. It has a public method CALCULATE with the
|
|
importing parameters iv_weight_kg, iv_service, iv_express, iv_member and the
|
|
returning parameter rv_price.
|
|
- The class has the public types ty_weight_kg, ty_amount and ty_service and the
|
|
public constants c_service_wash, c_service_dry and c_service_iron.
|
|
- The class has the private methods rate_per_kg and round_currency.
|
|
- A laundry order has a weight in kg, a service, an express flag and a member
|
|
flag. The services are WASH, DRY and IRON.
|
|
|
|
# 4. Contract
|
|
- Fix the class {{P}}LAUNDRY_PRICER in place.
|
|
- Do not change the public method signature, the public types or the public
|
|
constants.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
Apply the rules in this sequence. All other behavior stays the same.
|
|
1. The base price is the weight multiplied by the rate per kg. A member gets a
|
|
discount of 10 percent on the base price. An express order costs a fixed
|
|
surcharge of 5.00. The member discount does not apply to the express
|
|
surcharge. Add the express surcharge after the member discount.
|
|
2. The minimum order value is 10.00. Apply the minimum after all discounts and
|
|
surcharges. If the price after all discounts and surcharges is below 10.00,
|
|
the price is 10.00.
|
|
3. The ironing service uses its own rate. The rate for ironing is 1.50 per kg.
|
|
|
|
# 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 the public method signature, the public types or
|
|
the public constants.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write your own ABAP Unit tests for the class.
