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%+
