How do I verify validation errors?

You can use the 'negative_creates' field in the JSON spec to define tests that expect a 4xx error, ensuring your API validation logic is working as intended.

Do I need to manually start a server before running tests?

No, the skill can optionally spawn Hypercorn automatically if the 'runtime.spawn_hypercorn' field is enabled in your JSON specification.

Can I use this for CI/CD pipelines?

Yes, the script returns a non-zero exit code on any failure, making it perfect for integration into automated testing and deployment pipelines.

What is the ACP HTTP E2E Tester?

It is a Claude Code skill designed to automate end-to-end HTTP testing for plugins within the Mugen GenAI Microframework using JSON-based specifications.

How does it handle dynamic data like Row Versions?

The script supports placeholders like __ROW_VERSION__ and __ENTITY_ID__, which are automatically populated during the test flow to ensure sequential actions work correctly.

Security & Testing

Automates deterministic end-to-end HTTP testing for ACP-based plugins using JSON-driven specifications.

The ACP HTTP E2E Tester is a specialized tool for validating the resource and action surfaces of plugins within the Mugen GenAI Microframework. It allows developers to define complex test flows including authentication, tenant discovery, entity CRUD operations, and action transitions through a simple JSON specification. By leveraging Hypercorn and curl, it provides a repeatable, scriptable environment to catch regressions, verify HTTP status codes, and ensure event assertions meet business requirements during plugin development.

Key Features

01Support for both positive and negative validation path checks

02Integrated Hypercorn server management for one-command execution

03JSON-driven test specifications for repeatable HTTP flows

04Automated event sequence and status code assertions

05Dynamic placeholder support for entity IDs and row versions
