+# Development
+
+This guide covers setting up a development environment and running tests.
+
+## Setup
+
+Clone the repository and install dependencies:
+
+```bash
+git clone https://github.com/ggozad/haiku.rag.git
+cd haiku.rag
+uv sync
+```
+
+## Running Tests
+
+```bash
+uv run pytest
+```
+
+### Test Markers
+
+Tests use pytest markers to categorize them:
+
+- `@pytest.mark.integration` - Tests requiring local services (Docling models, etc.) that aren't available in CI
+- `@pytest.mark.asyncio` - Async tests (applied automatically via pytest-asyncio)
+- `@pytest.mark.vcr()` - Tests with HTTP call recording
+
+CI runs `pytest -m "not integration"` to skip integration tests.
+
+## HTTP Recording with VCR
+
+Tests use [pytest-recording](https://github.com/kiwicom/pytest-recording) (VCR.py) to record and replay HTTP calls. This allows tests to run without external services like Ollama or API providers.
+
+### How It Works
+
+1. Tests marked with `@pytest.mark.vcr()` record HTTP interactions to YAML cassettes
+2. On subsequent runs, HTTP calls are replayed from cassettes instead of hitting real services
+3. Cassettes are committed to the repository so CI can run tests without external dependencies
+
+### Recording New Cassettes
+
+When adding a new test that makes HTTP calls:
+
+1. Add the `@pytest.mark.vcr()` decorator to your test
+2. Run the test with the required services available (e.g., Ollama running)
+3. The cassette is automatically created on first run
+
+### Re-recording Cassettes
+
+To update an existing cassette, delete it and re-run the test, or use `--record-mode=rewrite`.
+
+### Running Without Cassettes (Live Mode)
+
+To run tests against real services instead of recorded cassettes:
+
+```bash
+uv run pytest --disable-recording
+```
+
+## Writing Tests
+
+### Common Fixtures
+
+Available fixtures from `tests/conftest.py`:
+
+- `temp_db_path` - Isolated temporary database
+- `temp_yaml_config` - Temporary config file
+- `allow_model_requests` - Enables pydantic-ai model calls
+
+### Example: Adding a New Test with VCR
+
+```python
+import pytest
+from haiku.rag.client import HaikuRAG
+
+
+@pytest.mark.asyncio
+@pytest.mark.vcr()
+async def test_my_feature(temp_db_path):
+    async with HaikuRAG(temp_db_path, create=True) as client:
+        doc = await client.create_document("Test content", uri="test://doc")
+        assert doc.id is not None
+```
+
+### Integration Tests
+
+For tests requiring local services that can't be mocked via VCR:
+
+```python
+@pytest.mark.integration
+@pytest.mark.asyncio
+async def test_pdf_visualization(temp_db_path):
+    # Test code that needs local PDF processing
+    pass
+```
+
+Integration tests are skipped in CI but run locally when you have the required services.
+
+## Linting and Formatting
+
+```bash
+uv run ruff check
+uv run ruff format
+uv run pyright
+```
+
+## Mock API Keys
+
+Tests automatically set mock API keys for providers that require them during client initialization. When running with VCR playback, these mock keys are sufficient since no real API calls are made.
+
+When recording new cassettes, set real API keys via environment variables:
+
+```bash
+ANTHROPIC_API_KEY=sk-ant-... uv run pytest tests/test_qa.py::test_qa_anthropic --record-mode=rewrite
+```
