 (commit: b24a88f)

test: agregar pruebas unitarias de los Services
 (commit: 41870ef)

Add comprehensive AdoptionService tests

Implement JPA integration tests for AdoptionService. Adds a @DataJpaTest class that uses TestEntityManager and Podam to create Shelter, Pet, Adopter and Adoption entities, with setup/teardown to seed test data. Tests cover creation (including validations for missing pet/date and pet availability), search (null and not-found cases), update (status change) and delete (only finished adoptions), and import the AdoptionService into the test context.

feat(api): add Postman collection with API design and documentation
 (commit: fc31cf7)

feat: agregar controllers para las entidades
 (commit: 22982ac)

feat: agregar controllers y colección Postman
 (commit: 1ebb4d5)

Add API controllers and update Postman collections

Add new REST controllers (Adoption, Review, Shelter, ShelterEvent, TrialStay) and update AdoptionHistoryController routing/usage. Update numerous Postman collection files: switch requests to localhost API URLs, add request/response examples, include examples paths, and refine collection/definition metadata. Modify several entities, repositories and services, and reorganize/replace test files (move to ZZZ folder and remove old tests) to align with the new endpoints and examples for local testing.
 (commit: 3e24ce1)

Add DTOs for pets domain and update tests

Introduce DTOs and detail variants for Adoption, Review, Shelter, ShelterEvent, and TrialStay to map entity fields and related ids/objects (new files added under src/main/java/co/edu/udistrital/mdp/pets/dto). TrialStayDetail is added as an empty subclass of TrialStayDTO. Update ReviewServiceTest to stabilize tests: ensure transient entities have null ids before persist, switch reviewDate handling to LocalDate, add entityManager.flush/clear calls, adjust test inputs and assertions (search/delete/update/invalid-rating cases) and use more robust id values for not-found/unauthorized scenarios.
 (commit: c4f32f1)

Map adoption in TrialStayDetailDTO

Add adoption mapping to TrialStayDetailDTO: import TrialStayEntity, add Lombok annotations, include an AdoptionDTO field and a constructor that populates it from the entity. Also apply minor formatting/whitespace cleanups across several DTO classes (AdoptionDTO, AdoptionDetailDTO, ReviewDTO, ReviewDetailDTO, ShelterDTO, ShelterDetailDTO, ShelterEventDTO, ShelterEventDetailDTO, TrialStayDTO).
 (commit: 21d63c4)

Refactor services, add validations & tests

Refactor Adopter, Message, Notification and Veterinarian services to use Entity types, add logging, transactional boundaries and stronger validation/error handling. Introduces search/list/update/delete methods, uses EntityNotFoundException for missing resources, enforces business-id immutability, and guards deletions when related records exist. MessageService adds sender/recipient extraction (reflection fallback) and edit/delete timing/ownership checks. NotificationService enforces user association and age check before deletion. VeterinarianService validates specialties and shelter association. Tests converted from Mockito unit tests to @DataJpaTest integration tests using TestEntityManager and PodamFactory, covering create/update/search/delete scenarios and error cases.

feat(api): implement controllers for all API resources
 (commit: c8946f2)

Refactor controllers, entities, DTOs and services

Add new REST controllers (AdopterController, PetController) and standardize endpoint names and response handling across controllers; ReviewController now uses ReviewDTO and maps entities to DTOs. Update DTOs (AdoptionDTO, AdoptionDetailDTO, ReviewDetailDTO, ShelterEventDTO) and add a toEntity helper for AdoptionDTO. Rework JPA entities: adjust types, initialize collections, change Lombok annotations, add JsonIgnore/JsonIgnoreProperties to prevent serialization/lazy-loading issues, and refine relationship mappings (e.g. eventCode -> Long, eager/lazy fetch adjustments). Services updated with transactional annotations, stronger validation and business rules (AdopterService and AdoptionService improved checks and messages, PetService simplified and made transactional). Minor repository/import cleanups and controller response consistency (use ResponseEntity.ok / noContent). These changes address serialization errors, NPEs, and tighten business logic and validation.

feat: connect controllers with services and implement DTO-Entity mapping

- Implemented MedicalEventController with service integration and mapping
- Implemented VaccinationRecordController aligned with service constraints
- Implemented AdoptionRequestController with full CRUD support
- Added missing relationship IDs in DTOs (petId, adopterId)
- Completed DTO ↔ Entity conversion logic
- Ensured consistency with service-layer validations and relationships
 (commit: dfbfb7d)

Refactor controllers, DTOs, entities and services

Convert controller endpoints to return DTOs and declare domain exceptions; map entities to DTOs in Adoption, Shelter, ShelterEvent controllers and add proper HTTP status annotations. Enforce business rules and validations in services: AdoptionService validates inputs, marks pet as ADOPTED and throws domain exceptions; PetService adds creation/update/delete validations, integrates ShelterRepository, and renames search methods to getPets/getPet; ShelterService centralizes validation and exposes getShelters; ShelterEventService simplifies date checks and update logic. Update entity models (PetEntity, AdoptionEntity, ShelterEntity) to include new fields, adjust JPA/JSON annotations and equals/hashCode exclusions to avoid cycles. Update DTOs (AdoptionDTO, ShelterEventDTO) and their entity conversion. Adjust tests to expect new behaviors and exception types.

Add Postman collection; update Review/TrialStay

Add a new Postman collection for the "Orejitas y Colas" API and update Java backend code related to reviews and trial stays. The commit introduces collections/Orejitas y Colas.postman_collection.json (CRUD examples and tests for shelters, reviews, trial stays, events, and adoptions) and modifies controller, DTO, service, and unit test files to align Review and TrialStay API behaviour and mappings:

- Updated: src/main/java/.../controllers/ReviewController.java, TrialStayController.java
- Updated: src/main/java/.../dto/ReviewDTO.java, TrialStayDTO.java
- Updated: src/main/java/.../services/ReviewService.java, TrialStayService.java
- Updated tests: src/test/java/.../services/ReviewServiceTest.java, TrialStayServiceTest.java

These changes sync API examples with backend logic and update unit tests accordingly.
 (commit: 727a2d9)

Add messaging/notification controllers and DTOs

Introduce REST controllers for Message, Notification and Veterinarian and add many DTO/detail classes for messaging, notifications, users, adopters, veterinarians, pets and related domain objects. Refactor entities to favor ID-based foreign keys (MessageEntity: senderId/recipientId, NotificationEntity: userId) and simplify VeterinarianEntity (Lombok changes, collection initializations, relationship rework). Update services: MessageService adds search/list operations; NotificationService tightens validation/defaults and changes deletion rules; VeterinarianService is simplified and specialty validation extracted. Adjust tests to use the new ID-based message fields and add tests for message search/list behavior.
 (commit: f79a138)

Add Postman items: vets, messages, notifications

Add new Postman collection folders for veterinarian, message, and notification resources. Each folder includes CRUD requests (POST/GET/PUT/DELETE) with test scripts that assert status codes, expected error messages, and set global IDs (e.g. veterinarian_id_1, notification_id_1). Endpoints target http://localhost:8080/api/...
 (commit: fab2e7e)

Refactor controllers to use DTOs and improve services

Convert controllers to accept and return DTOs, add DTO classes, and improve service validation/transactions. Controllers (AdoptionHistory, AdoptionTracking, Devolution, Report) now use DTO request/response objects, map DTOs to entities via toEntity helpers, return proper HTTP statuses and error messages (handle EntityNotFoundException and validation errors), and adjust request paths (e.g. /adoption-histories, /adoption-trackings, /devolutions, /reports). Added DTOs and detail DTOs for adoption history, tracking, devolution and reports (plus related Shelter/Adoption DTO usage). Services (AdoptionTrackingService, DevolutionService, ReportService) were hardened: added null/adoption/shelter existence checks, transactional annotations, clearer method names (create/findAll/findById/update/delete), and safer partial updates. Tests updated to match new service APIs and behaviors (AdoptionTrackingServiceTest, DevolutionServiceTest), and a new ReportServiceTest was added while an outdated test class was removed. Overall this change improves API shape, error handling, and data validation.
 (commit: 5f128f3)

Add adoption, devolution, vaccines & medical

Extend Postman collection with new request groups and endpoints: Adoption History, Adoption Tracking, Devolution, Report; add Vaccines endpoints and example responses under veterinarian; add Medical Events POST and response examples. Also adjust several test expectations and prerequest scripts (fix error message strings and minor script entries) and include sample request bodies for the new endpoints.
