🚀 Quick Start

# Install test dependencies
uv sync --extra dev

# Run all unit tests (fast)
make test-unit

# Run with coverage
make test-coverage

# Run specific category
make test-api

🧪 Key Features

1. Fixture-Based Testing (No Mocks!)

• Real OpenSearch clients for integration tests
• Actual service instances
• Proper cleanup with yield pattern
• Reusable across test modules

2. Async Support

• Full pytest-asyncio integration
• Async fixtures for OpenSearch
• Proper event loop handling

3. Coverage Reporting

• Terminal output with missing lines
• HTML reports in htmlcov/
• XML reports for CI/CD
• Branch coverage tracking

4. Organized Test Structure

• Mirrors source code structure
• Easy to find relevant tests
• Clear separation of concerns

5. CI/CD Ready

• Fast unit tests for quick feedback
• Separate integration tests
• Coverage enforcement
• Configurable markers

📈 Coverage Goals

Current: Growing from 1.44% (utils only) Target: 70%+ overall coverage

Tested modules:

• ✅ utils/embeddings.py - 100%
• ✅ utils/hash_utils.py - 88%
• ⏳ services/* - To be expanded
• ⏳ api/* - To be expanded
• ⏳ connectors/* - To be expanded

🔧 Integration Tests

Integration tests require external services:

# Start infrastructure
make infra  # Starts OpenSearch, Langflow

# Run integration tests
make test-integration

# Or skip integration tests
pytest -m "not requires_opensearch and not requires_langflow"

📝 Sample Test

import pytest

@pytest.mark.unit
class TestEmbeddingDimensions:
    def test_get_openai_embedding_dimensions(self):
        """Test getting dimensions for OpenAI models."""
        assert get_embedding_dimensions("text-embedding-ada-002") > 0

🎓 Best Practices Implemented

1. ✅ Use fixtures instead of mocks
2. ✅ Organize tests by category with markers
3. ✅ Keep unit tests fast
4. ✅ Proper resource cleanup
5. ✅ Test one thing per test
6. ✅ Descriptive test names
7. ✅ Follow AAA pattern (Arrange, Act, Assert)
8. ✅ Independent tests
9. ✅ Clear documentation

🔄 Next Steps

To expand test coverage:

1. Add more service tests
2. Add API integration tests
3. Add model processing tests
4. Add authentication tests
5. Add flow management tests
6. Increase coverage to 70%+
