Mooncake Data Mocking Platform – Design, Implementation, and Promotion

Mooncake is a unified data‑mocking platform developed by the DeWu technology team to provide fast, multi‑scenario mock data for front‑end and client applications during development and testing.

The platform addresses common problems such as unavailable back‑end data, high cost of data generation, and difficulty switching between scenarios. It enables developers to create mock interfaces manually or from YAPI, supports scene and scene‑group switching, and offers QR‑code generation for quick testing.

Key functionalities include a non‑intrusive mock proxy plugin for Chrome (injecting MockProxy.js to hijack Fetch and XHR), an online configuration service that stores spaces, interfaces, scenes, and supports timeout, rate‑limit, and caching, as well as a capture panel that works like Charles to record real requests and generate mock scenarios.

The system consists of three layers: an online configuration platform, a mock proxy layer (handling H5, SSR, Android, iOS, Flutter), and mock injection (currently for H5). It supports YAPI data generation, automatic mock matching, request interception, interface change notifications, and link verification.

Promotion strategies involve internal product demos, over 20 sharing sessions, documentation tailored to users and scenarios, and continuous feedback loops. The platform expanded from front‑end teams to testing and client developers, with usage metrics tracked bi‑weekly and user surveys guiding further improvements.

To date, Mooncake has served hundreds of internal users, created tens of thousands of mock scenes, and maintains over a hundred active users per bi‑weekly cycle. Future plans include deeper integration with data‑service platforms, automated testing pipelines, and evolving into a comprehensive R&D testing tool covering API documentation, service marketplace, mock data, and automation.
