Total: 26 initial test cases covering critical functionality

2. Test Configuration & Fixtures ✅¶

tests/conftest.py - Comprehensive fixture library: - Database fixtures (session-scoped engine, function-scoped sessions) - FastAPI test client with DB override - Environment variable mocking - Authentication fixtures (users, API keys, headers) - Test data fixtures (presentations, templates) - Mock service fixtures (AI providers, N8N, storage) - Pytest hooks for auto-marking tests - Utility functions for assertions

tests/pytest.ini - Configuration: - Test discovery settings - Coverage configuration - 9 custom markers (unit, integration, api, cli, frontend, e2e, ai, slow, smoke) - Code coverage exclusions - Asyncio mode enabled

3. Test Categories Implemented ✅¶

Unit Tests (tests/unit/)¶

• ✅ Configuration loading and validation
• ✅ Environment variable handling
• ✅ Database URL format validation
• ✅ AI provider validation
• ✅ Storage provider validation

Coverage: Core configuration module

API Tests (tests/api/)¶

• ✅ POST /api/presentations/generate - Success case
• ✅ POST /api/presentations/generate - Missing template
• ✅ POST /api/presentations/generate - Invalid data
• ✅ POST /api/presentations/generate - No authentication
• ✅ GET /api/presentations/status/{id} - Get status

• ✅ GET /api/presentations/download/{id} - Not ready
• ✅ GET /api/presentations/list - List presentations
• ✅ End-to-end workflow test (generate → status → download)

Coverage: Presentations API (primary revenue-generating feature)

CLI Tests (tests/cli/)¶

• ✅ Generate with template ID
