# 1. Goal
|
|
Calculate the consultation fee of a visit at a veterinary clinic. A clinic program
|
|
calls the calculation before it prints the invoice. The program needs the fee and
|
|
one reason code for each visit.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_VET_FEE exists in package $TMP. It is active. Read the
|
|
interface. It contains the types, the constants and the method signature that
|
|
the calculation uses.
|
|
- The interface is not part of this task.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}VET_FEE_CALC in package $TMP.
|
|
- The class is public, final, and has a public constructor without parameters.
|
|
- The class implements {{P}}IF_VET_FEE.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
The rules run in this sequence. Rules 1 to 3 prepare and check the input.
|
|
Rules 4 to 8 calculate the fee.
|
|
1. Remove all spaces from the species. Convert all letters to upper case.
|
|
2. The species must be DOG, CAT, RABBIT, BIRD or REPTILE. If not, the
|
|
calculation returns the reason SPECIES and a fee of 0.
|
|
3. The weight must be above 0 kg and at most 200 kg. If not, the calculation
|
|
returns the reason WEIGHT and a fee of 0.
|
|
4. The base fee depends on the species:
|
|
DOG 45.00, CAT 35.00, RABBIT 25.00, BIRD 18.00, REPTILE 30.00.
|
|
5. The medication fee is 2.00 for each started kilogram of weight above 5 kg.
|
|
Examples: 5.000 kg gives 0.00, 5.001 kg gives 2.00, 7.000 kg gives 4.00,
|
|
7.001 kg gives 6.00.
|
|
6. If the visit is an emergency, add half of the base fee. For a dog the
|
|
surcharge is 22.50.
|
|
7. If the animal is a registered patient of the clinic, subtract 10 percent of
|
|
the base fee plus the medication fee. The emergency surcharge is not part of
|
|
the discount. The base fee plus the medication fee is always a whole number
|
|
of euro, so the discount has at most one decimal place.
|
|
8. The fee is the base fee plus the medication fee plus the emergency surcharge
|
|
minus the registered discount. The calculation returns the reason OK and
|
|
this fee.
|
|
|
|
# 6. Constraints
|
|
- Release target: 7.58.
|
|
- 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_VET_FEE.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write your own ABAP Unit tests for the class.
