@@ -101,6 +101,16 @@ Each Nextcloud app has a corresponding server module that:
- Tests are marked with `@pytest.mark.integration` for selective running
- **Important**: Integration tests run against live Docker containers. After making code changes to the MCP server, rebuild only the MCP container with `docker-compose up --build -d mcp` before running tests
#### Testing Best Practices
- **Always restart MCP server** after code changes with `docker-compose up --build -d mcp`
- **Use existing fixtures** from `tests/conftest.py` to avoid duplicate setup work:
- `nc_mcp_client` - MCP client session for tool/resource testing
- `nc_client` - Direct NextcloudClient for setup/cleanup operations
- `temporary_note` - Creates and cleans up test notes automatically
- `temporary_addressbook` - Creates and cleans up test address books
- `temporary_contact` - Creates and cleans up test contacts
- **Avoid creating standalone test scripts** - use pytest with proper fixtures instead
### Configuration Files
- **`pyproject.toml`** - Python project configuration using uv for dependency management
