# Integration Tests Summary - Phase 3.2 TDD

**Status**: ✅ COMPLETE - All integration tests created and in TDD RED phase
**Date**: 2025-09-12

## Phase 3.2: TDD Integration Tests (User Stories) - COMPLETED

All 5 integration tests have been implemented and are properly structured for TDD workflow:

- Patient created in WordPress users table with correct role
- Patient-clinic mapping established in KiviCare database
- Patient metadata (phone, address, birth_date) stored correctly
- Patient appears in clinic patient lists
- Cross-clinic access properly denied

---

### ✅ T018 - Encounter Workflow (test-encounter-workflow.php)
**User Story**: Doctor creates encounter with multiple prescriptions

**Test Coverage**:
- ✅ Complete encounter creation with detailed medical data

- ✅ Automatic appointment status update to completed
- ✅ Automatic bill generation upon encounter completion
- ✅ Patient access to own encounter data (with sensitive data filtering)
- ✅ WordPress action/hook workflow events
- ✅ Data integrity validation and error handling
- ✅ Prescription validation with drug interaction checks
- ✅ Role-based encounter creation permissions

**Key Assertions**:
- Encounter linked to appointment, patient, and doctor
- Prescriptions properly associated with encounter
- Bill automatically generated with correct amounts
- Appointment marked as completed
- Workflow events properly triggered
- Patient sees filtered encounter data (no vital signs)

**Test Coverage**:
- ✅ Multi-doctor same clinic data sharing
- ✅ Cross-clinic data isolation and security
- ✅ Collaborative encounter updates between doctors
- ✅ Clinic admin full data access permissions
- ✅ Data access auditing and logging
- ✅ Security testing with SQL injection attempts
- ✅ Data filtering by clinic membership

**Key Assertions**:
- Doctors in same clinic can access shared patient data
- Doctors can update encounters created by colleagues
- Cross-clinic access properly denied (403 errors)
- Clinic admin sees all clinic data
- Audit logs created for all data access operations
- No data leakage between clinics
- SQL injection attempts properly blocked

### ✅ T020 - Automatic Billing Generation (test-billing-automation.php)
**User Story**: Automatic billing generation from encounters and services

**Test Coverage**:
- ✅ Complete automatic billing workflow
- ✅ Service-based billing calculation
- ✅ Dynamic service addition during encounter
- ✅ Bill amount recalculation when services added
- ✅ Payment processing workflow
- ✅ Discounts and insurance claim processing
- ✅ Error handling for billing edge cases
- ✅ Role-based billing permissions
- ✅ Billing reports and analytics

**Key Assertions**:
- Bills automatically generated when encounter created
- Bill amounts calculated correctly from appointment services
- Additional services update bill totals in real-time
- Payment status properly tracked and updated
- Discount calculations applied correctly
- Insurance claims created and managed
- Billing permissions enforced by role
- Comprehensive billing reports generated

---

### ✅ T021 - Role-Based Access Control (test-role-permissions.php)
**User Story**: Complete role-based permissions across all API endpoints

**Test Coverage**:
- ✅ Complete permission matrix for all roles (admin, doctor, patient, receptionist)
- ✅ All API endpoints tested for each role
- ✅ Data filtering based on user role and clinic access
- ✅ API key authentication with scoped permissions
- ✅ Permission inheritance and role hierarchy
- ✅ Custom role support with capability mapping

**Permission Matrix Tested**:
- **Administrator**: Full access to all endpoints
- **Doctor**: Medical access, patient management, encounter creation
- **Patient**: Own data only, read-only medical records
- **Receptionist**: Appointments, basic patient data, billing

**Key Assertions**:
- All endpoints return correct HTTP status codes per role
- Data properly filtered by user's clinic access
- API keys work with scoped permissions
- Custom roles inherit permissions correctly
- Cross-clinic access denied consistently

## Technical Implementation Details

### API Endpoints Corrected
- ✅ All endpoints updated to use `/wp-json/kivicare/v1/` namespace (aligned with quickstart.md)
- ✅ Consistent with KiviCare plugin API specification

### TDD RED Phase Compliance
- ✅ All tests marked with `markTestIncomplete()` 
- ✅ Tests WILL FAIL until business logic implemented
- ✅ Comprehensive test scenarios covering all user stories
- ✅ Proper PHPUnit structure and WordPress test framework integration

### Test Infrastructure
- ✅ Base test case class (`Care_API_Test_Case`) with helper methods
- ✅ Mock KiviCare database structure
- ✅ Test user creation for all roles
- ✅ REST API testing framework setup
- ✅ Database cleanup and isolation

### User Story Validation Alignment
- ✅ Tests align with scenarios in `specs/001-care-api-sistema/quickstart.md`
- ✅ All validation checklist items covered
- ✅ Error handling scenarios included
- ✅ Performance considerations tested
- ✅ Security validation implemented
