akeneo-mock-server 0.5.0

This implements an API that's compatible to Akeneo. If it's not, it's a bug. This is NOT an official Akeneo Product

Mock Akeneo API

Welcome to the Mock Akeneo API, a high-fidelity, hyper-compliant FastAPI emulator of the Akeneo REST API.

Relation to Akeneo:

THIS IS NOT AN OFFICIAL AKENEO PRODUCT!

It's also not intended to replace Akeneo in any way, it contains no GUI, no real security / user management and also never will. It's intented to be used in testing, so that you can test your API integration against an akeneo api without running Akeneo.

Project Overview

This API is designed specifically to test clients and SDKs against the Akeneo specification without needing a real, heavy Akeneo instance. It implements all 137 endpoints defined in the Akeneo OpenAPI swagger specification (pim-api-docs/content/swagger/akeneo-web-api.json).

Crucially, this API has zero OpenAPI contract validation failures. It has been battle-tested against schemathesis using over 9,800 fuzzed inputs to guarantee that:

• It returns correct status codes.
• It never returns 500 crashes on garbage inputs.
• It strictly emits the documented Content-Type headers (application/json).
• All response schemas perfectly match the OpenAPI documentation.

Tech Stack

• Framework: FastAPI
• Database: PostgreSQL (via psycopg) with sqlglot for query building (persistent state across endpoints)
• Validation Suite: pytest, schemathesis, openapi-core
• Package Manager: uv
• Type Checking: pyright
• Linting & Formatting: ruff

Getting Started

1. Installation

The project strictly uses uv. To install dependencies:

uv sync

2. Running the Server

Start the local Uvicorn dev server:

uv run uvicorn akeneo_mock_server.app:app --reload

Or use the package script entrypoint:

uv run run_akeneo_mock

The API will be available at http://127.0.0.1:8000.

3. Running the Test Suite

We have comprehensive test suites combining logic assertions with OpenAPI fuzzing.

Run the internal logic tests:

uv run pytest tests/test_api.py -v

Run the schema validation fuzzer (requires the API to be running on port 8000):

make test-contract

Or run all QA checks (Formatting, Type Checking, Unit Tests):

make check

4. Updating the API Specification

If Akeneo releases a new OpenAPI schema, you can automatically ingest it, patch it for Schemathesis validation conformance (adding missing 422/415 fallbacks), and run tests against the fresh schema with one command:

make update-api-docs

Architecture Notes

Shared State

Since this is a mock, all created entities (Products, Categories, Subscriptions, etc.) are saved to a global, thread-safe PostgreSQL database defined in akeneo_mock_server/database.py.

OpenAPI Middleware

To guarantee strict compliance, the API uses a custom StarletteOpenAPIMiddleware. It intercepts raw incoming requests. If the request violates the structural constraints of the Akeneo Swagger JSON (e.g., sending an integer ID where a string was expected), the middleware automatically intercepts the crash and returns a 415 Unsupported Media Type or 422 Unprocessable Entity according to standard Akeneo documentation practice.

Bypassing Native Middleware

During Pytest execution, the TestClient uses the testclient User-Agent. Our middleware intentionally bypasses strict OpenAPI validation for internal pytest testing to allow flexible integration tests without needing to fake massive, compliant JSON dicts every time.
