# (DD45) Business Logic — PetTypeFormatterTests.makePetTypes() [14 LOC]

| Field | Value |
|-------|-------|
| Fully Qualified Name | `org.springframework.samples.petclinic.owner.PetTypeFormatterTests` |
| Layer | Utility / Test Support |
| Module | `owner` (Package: `org.springframework.samples.petclinic.owner`) |

## 1. Role

### PetTypeFormatterTests.makePetTypes()

This helper method constructs a fixed in-memory collection of `PetType` objects used by the formatter test fixture. Its business role is not to persist, query, or transform production data, but to provide deterministic sample master-data records that simulate the pet type reference list expected by the owner domain. The method creates two canonical animal categories, `Dog` and `Bird`, and returns them as a `List<PetType>` so test cases can verify formatter behavior against known reference values.

From a system perspective, this method acts as a test data factory for the owner package’s formatting logic. It follows a simple factory-style initialization pattern: create the collection, instantiate lightweight domain objects, initialize their business names, and return the completed sample set. There are no conditional branches, loops, or external integrations, which makes the method a stable fixture provider for repeatable unit tests.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["makePetTypes()"])
    CREATE_LIST(["Create empty ArrayList<PetType>"])
    ADD_DOG(["Instantiate anonymous PetType"])
    SET_DOG(["setName(\"Dog\")"])
    ADD_TO_LIST_1(["Add Dog pet type to list"])
    ADD_BIRD(["Instantiate anonymous PetType"])
    SET_BIRD(["setName(\"Bird\")"])
    ADD_TO_LIST_2(["Add Bird pet type to list"])
    RETURN_LIST(["Return petTypes list"])

    START --> CREATE_LIST
    CREATE_LIST --> ADD_DOG
    ADD_DOG --> SET_DOG
    SET_DOG --> ADD_TO_LIST_1
    ADD_TO_LIST_1 --> ADD_BIRD
    ADD_BIRD --> SET_BIRD
    SET_BIRD --> ADD_TO_LIST_2
    ADD_TO_LIST_2 --> RETURN_LIST
```

This method executes a straight-line initialization flow. It first allocates an empty `ArrayList` to hold sample pet type records, then creates the first anonymous `PetType` instance and assigns the display name `Dog`. The method adds that initialized object to the list, repeats the same procedure for a second anonymous `PetType` with the display name `Bird`, and finally returns the populated list to the caller.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | - |

External state read by the method: none. The method does not read instance fields, static fields, or external context; it only creates local sample objects and returns them.

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | `NamedEntity.setName` | NamedEntity | - | Calls `setName` in `NamedEntity` |

Analyze all method calls within this method and classify each as a CRUD operation.
Use the pre-computed evidence above. If SC Code or Entity/DB is missing, try to infer from:
- The **SC Code** (Service Component code, e.g., `EKK0361A010SC`, `EKK1081D010CBS`) — look at the class name of the called method or its containing class.
- The **Entity/DB tables** — search for table name constants (often `KK_T_*` pattern), SQL references, or entity names in the called method source code.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| U | `setName` | NamedEntity | PetType (in-memory domain object) | Initializes the business name of a sample pet type for test verification. |
| C | `new ArrayList<PetType>()` / `new PetType()` | - | In-memory test fixture | Creates transient objects only; no persistence layer is involved. |

## 5. Dependency Trace

### Pre-computed evidence from code analysis graph:

No screen/batch entry points found within 8 hops. Direct callers found: 2 methods.
Terminal operations from this method: `setName` [-], `setName` [-]

Trace who calls this method and what this method ultimately calls.
Use the pre-computed evidence and caller search results from Step 2 above.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Test method: `given(types.findPetTypes()).willReturn(makePetTypes())` | `PetTypeFormatterTests.formatCollection` -> `PetTypeFormatterTests.makePetTypes` | `setName [U] PetType (in-memory)` |
| 2 | Test method: `given(types.findPetTypes()).willReturn(makePetTypes())` | `PetTypeFormatterTests.parseCollection` -> `PetTypeFormatterTests.makePetTypes` | `setName [U] PetType (in-memory)` |

## 6. Per-Branch Detail Blocks

**Block 1** — [SEQUENTIAL INITIALIZATION] `(no condition)` (L82-L95)

> Builds a deterministic sample list of pet types for unit testing.

| # | Type | Code |
|---|------|------|
| 1 | SET | `List<PetType> petTypes = new ArrayList<>();` // create empty sample collection |
| 2 | EXEC | `petTypes.add(new PetType() { ... });` // create first anonymous sample object |
| 3 | EXEC | `setName("Dog");` // assign display name for the first sample pet type |
| 4 | EXEC | `petTypes.add(...)`; // add the first sample pet type to the list |
| 5 | EXEC | `petTypes.add(new PetType() { ... });` // create second anonymous sample object |
| 6 | EXEC | `setName("Bird");` // assign display name for the second sample pet type |
| 7 | EXEC | `petTypes.add(...)`; // add the second sample pet type to the list |
| 8 | RETURN | `return petTypes;` // return the completed sample collection |
