metersphere/metersphere ? reverse-engineered prompt

Build me a web app like MeterSphere, a modern testing platform for teams.

I want a clean interface where people can manage test cases, organize test plans, run API tests, mock endpoints, see reports, and track defects all in one place. It should feel easy to use for non experts, with an AI helper that can suggest or generate test cases and API tests from simple input. Support team based workspaces so different groups can collaborate without everything feeling like a single user tool.

Please make it a full stack app with a polished frontend and a solid backend, and wire it up so it can be started locally with Docker. Use sensible storage and background processing for things like execution history, reports, files, and async jobs. If you need to, look up current docs online while building it. Focus on making the core product work end to end first, then add any obvious nice touches for usability.
