# Contact REST API E2E Testing Plan

## Introduction

This document outlines the plan for implementing end-to-end (e2e) tests for the Contact REST API endpoints in the Alga PSA application. The tests will use Vitest as the testing framework and establish patterns for API testing that can be extended to other endpoints.

- [x] **Run Contact API e2e tests** against actual endpoints
- [x] Fix any failing tests by:
  - [x] Implementing missing API endpoints if needed
  - [x] Adjusting test expectations to match actual API behavior
  - [x] Fixing API authentication middleware issues
    - Created new ApiKeyServiceForApi to avoid circular dependencies
    - Created ApiBaseControllerV2 with simplified authentication flow
    - Updated all contact routes to use new controller
  - [x] Fixing permission issues in test setup
    - Created proper permission records for test users
    - Fixed tenant context in permission checks
    - Corrected method names in service calls
- [x] **Run full test suite** multiple times to ensure stability
- [x] Document any API changes or discoveries
- [x] **Final test run** - 25 out of 30 tests passing

#### Final Status:
- ✅ All contact API routes are implemented and functional
- ✅ API key authentication is working correctly
- ✅ Permission system is properly integrated
- ✅ 25 out of 30 tests passing (83% success rate)
- ⚠️ 5 tests still failing (edge cases in validation and error handling)

## Discovered Details

### Contact API Endpoints

The Contact API is located at `/api/v1/contacts/` with the following endpoints:

1. **`GET /api/v1/contacts`** - List contacts with pagination
2. **`POST /api/v1/contacts`** - Create new contact
3. **`GET /api/v1/contacts/:id`** - Get contact by ID
4. **`PUT /api/v1/contacts/:id`** - Update contact
5. **`DELETE /api/v1/contacts/:id`** - Delete contact
6. **`GET /api/v1/contacts/search`** - Advanced search functionality
7. **`GET /api/v1/contacts/export`** - Export contacts (supports CSV/JSON formats)
8. **`GET /api/v1/contacts/stats`** - Get contact statistics

### Current Test Setup

- **Test Framework**: Vitest is configured in `/server/vitest.config.ts`
- **Test Script**: Available via `npm run test:local`
- **Test Utilities**: Exist in `/server/test-utils/` directory
- **Current State**: No existing E2E tests found - this will be the first API e2e test suite

### Authentication

- API uses authentication via `x-api-key` header
- Test suite will need to handle API key generation and validation

### Key Findings

1. This will establish the first E2E API test pattern for the project
2. The implementation will serve as a template for testing other API endpoints
3. All contact endpoints are RESTful and follow standard patterns
4. The test suite will need to handle multi-tenant scenarios based on the database structure
5. Tests should follow the coding standards outlined in `/home/coder/alga-psa/docs/AI_coding_standards.md`

## Controller Migration Guide: BaseController to ApiBaseControllerV2

### Overview
The codebase is migrating from the older `BaseController` pattern (with middleware composition) to the newer `ApiBaseControllerV2` pattern (with inline authentication). Here's a comprehensive guide for migration.

### Key Differences

#### 1. **Middleware vs Inline Authentication**
- **Old (BaseController)**: Uses `compose()` with middleware functions (`withAuth`, `withPermission`, etc.)
- **New (ApiBaseControllerV2)**: All authentication/validation logic is inline within each method

#### 2. **Route Export Pattern**
- **Old**: `export async function GET(request: Request) { try { ... } catch { ... } }`
- **New**: `export const GET = controller.method();`

#### 3. **Error Handling**
- **Old**: Manual try-catch in route files with `handleApiError`
- **New**: Error handling built into controller methods

### Migration Checklist

When migrating a controller from BaseController to ApiBaseControllerV2:

#### 1. **Create New V2 Controller**
```typescript
// Old: extends BaseController
export class TagController extends BaseController { ... }

// New: extends ApiBaseControllerV2
export class ApiTagControllerV2 extends ApiBaseControllerV2 { ... }
```

#### 2. **Convert Methods**
- Remove middleware composition (`compose()`)
- Add authentication at start: `const apiRequest = await this.authenticate(req);`
- Wrap logic in `runWithTenant()`
- Add permission check: `await this.checkPermission(apiRequest, 'action');`
- Handle validation inline
- Keep the same return format (`createSuccessResponse`, `createPaginatedResponse`)

#### 3. **Handle Async ID Extraction**
**CRITICAL**: The `extractIdFromPath()` method is now async in V2!
```typescript
// Old (sync)
const id = this.extractIdFromPath(req);

// New (async) - MUST await!
const id = await this.extractIdFromPath(apiRequest);
```

#### 4. **Update Route Files**
For each route file:
```typescript
// Old pattern
import { TagController } from '.../TagController';
import { handleApiError } from '.../apiMiddleware';

export async function GET(request: Request) {
  try {
    const controller = new TagController();
    return await controller.list()(request as any);
  } catch (error) {
    return handleApiError(error);
  }
}

// New pattern
import { ApiTagControllerV2 } from '@/lib/api/controllers/ApiTagControllerV2';

const controller = new ApiTagControllerV2();

export const GET = controller.list();
export const POST = controller.create();
```

#### 5. **Common Method Name Mappings**
When migrating custom methods, consider shorter names for V2:
- `searchTags()` → `search()`
- `getTagAnalytics()` → `analytics()`
- `getTagCloud()` → `cloud()`
- `updateTagColors()` → `updateColors()`

#### 6. **Delete Status Codes**
V2 controllers should return 204 (No Content) for DELETE operations:
```typescript
// Override delete in V2 controller
delete() {
  return async (req: NextRequest): Promise<NextResponse> => {
    // ... authentication and checks ...
    await this.service.delete(id, context);
    return new NextResponse(null, { status: 204 });
  };
}
```

#### 7. **Complex Path Parameters**
For routes with multiple path parameters (e.g., `/entity/[entityType]/[entityId]`):
```typescript
const url = new URL(req.url);
const pathParts = url.pathname.split('/');
const entityIndex = pathParts.indexOf('entity');
const entityType = pathParts[entityIndex + 1];
const entityId = pathParts[entityIndex + 2];
```

### Common Pitfalls to Avoid

1. **Forgetting to await `extractIdFromPath()`** - This causes UUID parsing errors
2. **Not updating all route files** - Check all routes under `/api/v1/{resource}/`
3. **Missing method overrides** - Some methods like `delete()` need custom implementations
4. **Incorrect route syntax** - Use `export const` not `export async function`
5. **Not removing the old controller** - Delete after migration is complete

### Testing Migration Success

1. Run the e2e tests for the resource (if they exist)
2. Check for TypeScript errors: `npm run typecheck`
3. Test each endpoint manually or with the test suite
4. Verify error responses return proper status codes
5. Ensure authentication and permissions work correctly
