Running Tests

# Run tests for a specific package
mise run test packages/sie_sdk
mise run test packages/sie_server

# Run integration tests (requires a running SIE server)
mise run test integrations/sie_langchain

Test Types

Type	Requires Server	When to Run
Unit tests	No	Every PR
Integration tests	Yes	When changing SDK/server interface
Docker tests	Docker	When changing Dockerfiles
GPU tests	GPU worker	When changing inference pipeline

---

Code Style

# Format code
mise run lint -f

# Type checking
mise run typecheck

SIE uses standard Python formatting and type annotations throughout.

Adding a New Model

See Adding Models for the full guide. In summary:

1. Create a YAML config in packages/sie_server/models/
2. Map to an existing adapter (or write a new one in packages/sie_server/src/sie_server/adapters/)
3. Add quality targets with sie-bench
4. Submit a PR

---

Adding a New Integration

1. Create the package directory under integrations/:

   integrations/sie_myframework/
   ├── src/sie_myframework/
   │   ├── __init__.py
   │   └── embeddings.py
   ├── tests/
   │   ├── test_embeddings.py
   │   └── test_integration.py
   └── pyproject.toml

2. Implement the framework primitives:

   • encode() → framework’s embedding interface
   • score() → framework’s reranker/compressor interface
   • extract() → framework’s tool/extractor interface

3. Use shared test fixtures from integrations/conftest.py:

   • mock_sie_client - mocked SIEClient for unit tests
   • sie_server_url - real server URL for integration tests

4. Add tests and submit a PR

---

PR Workflow

1. Fork the repository
2. Create a feature branch: git checkout -b feature/my-change
3. Make your changes with tests
4. Run mise run lint -f && mise run typecheck
5. Submit a pull request
