Phase 1 End-to-End Demonstration

This script demonstrates the Phase 1 Memory & Coverage system working end-to-end:
1. Creates a test specification
2. Stores test patterns to memory
3. Retrieves similar tests
4. Shows coverage analysis

    print_section("HOW TO TEST FROM THE UI")

    print("""
The Phase 1 Memory & Coverage system is integrated into the existing pipeline.

To see it working from the UI/dashboard:

1. START THE WEB DASHBOARD:
   ```bash
   cd /Users/nihadmammadli/test-automation/playwright-agent
   ./start-ui.sh
   ```
   Or:
   ```bash
   docker-compose up -d db
   cd orchestrator && python -m uvicorn api.main:app --port 8001 &
   cd web && npm run dev
   ```

2. ACCESS THE DASHBOARD:
   - Frontend: http://localhost:3000
   - Backend API: http://localhost:8001
   - API Docs: http://localhost:8001/docs

3. CREATE A TEST SPEC:
   - Go to http://localhost:3000/specs
   - Click "New Spec" or use an existing spec
   - Write your test in markdown format

4. RUN THE TEST WITH MEMORY:
   - Click "Run Test" button
   - The pipeline will automatically:
     * Use memory to find similar tests (Planner stage)
     * Store successful patterns (Exporter stage)
     * Track coverage (Operator stage)

5. VIEW COVERAGE (NEW ENDPOINTS):
   - GET http://localhost:8001/api/coverage/summary
   - GET http://localhost:8001/api/coverage/gaps
   - GET http://localhost:8001/api/coverage/suggestions

6. CHECK MEMORY DATA:
   - Vector DB data stored in: ./data/chromadb/
   - Graph data stored in: ./data/graphs/
   - View with SQLite browser for: ./data/testdb (PostgreSQL)

CLI USAGE:
```bash
# Run with memory enabled (default)
python orchestrator/cli.py specs/your-test.md

# Analyze coverage for a URL
python orchestrator/workflows/coverage_analyzer.py https://example.com

# View stored patterns
python -c "
from orchestrator.memory import MemoryManager
manager = MemoryManager(project_id='my_project')
patterns = manager.vector_store.get_all_patterns()
print(f'Total patterns: {len(patterns)}')
for p in patterns[:5]:
    print(f\"  - {p['metadata'].get('action', '')} on {p['metadata'].get('target', '')}\")
"
```

ENVIRONMENT VARIABLES:
```bash
# Enable memory (default: true)
MEMORY_ENABLED=true

# OpenAI API for embeddings
OPENAI_API_KEY=your-key-here

# ChromaDB persistence
CHROMADB_PERSIST_DIRECTORY=./data/chromadb

# Project isolation
# (Set automatically based on spec folder or project name)
```

DATABASE TABLES (NEW):
```sql
-- View stored patterns
SELECT * FROM test_patterns ORDER BY success_rate DESC LIMIT 10;

-- View coverage gaps
SELECT * FROM coverage_gaps WHERE resolved = false;

-- View discovered elements
SELECT * FROM discovered_elements ORDER BY last_seen DESC;

-- View projects
SELECT * FROM projects;
