End-to-end tests for MCP Gateway main APIs.
Copyright 2025
SPDX-License-Identifier: Apache-2.0
Authors: Mihai Criveti
This module contains comprehensive end-to-end tests for all main API endpoints in main.py.
These tests are designed to exercise the entire application stack with minimal mocking,
using only a temporary SQLite database and bypassing authentication.
The tests cover:
- Health and readiness checks
- Protocol operations (initialize, ping, notifications, completion, sampling)
- Server management (CRUD, SSE endpoints, associations with tools/resources/prompts)
- Tool management (CRUD, REST/MCP integration types, metrics)
- Resource management (CRUD, templates, caching)
- Prompt management (CRUD, template execution with arguments)
- Gateway federation (registration, connectivity)
- Root management (filesystem roots for resources)
- Utility endpoints (RPC, logging, WebSocket/SSE)
- Metrics collection and aggregation
- Version information
- Authentication requirements
- OpenAPI documentation
Each test class corresponds to a specific API group, making it easy to run
isolated test suites for specific functionality. The tests use a real SQLite
database that is created fresh for each test run, ensuring complete isolation
and reproducibility.
Note: Admin API endpoints (/admin/*) are tested separately when MCPGATEWAY_ADMIN_API_ENABLED=true
TODO:
1. Test redis
2. Test with sample MCP server(s) in test scripts
