Automate FastAPI and Svelte webapp testing by orchestrating local server execution with a Playwright driver, which handles startup, teardown, and automated smoke testing of catalog navigation flows. This approach ensures consistent local environments without manual port configuration.

Capture responsive screenshots during webapp development by running a Playwright-based visual verification driver that interacts with the headless browser and generates screenshots across multiple configured breakpoints for the registry metadata catalog interfaces.

Yes, you need to install Bun and uvicorn, along with uv and Playwright, because the automated visual testing requires a configured Python and Bun environment to orchestrate the FastAPI backend and Svelte frontend servers.

Prevent port collisions when running local backend and frontend servers by using automated orchestration that manages startup and teardown with automatic port management, ensuring the FastAPI and Svelte servers do not conflict during local execution.

Verify metadata schema changes render correctly by executing an automated smoke test that orchestrates the local FastAPI and Svelte servers, navigates the catalog browsing flow, and captures visual screenshots to confirm the interface renders the updated metadata accurately.

You should not use automated orchestration for local webapp testing if your environment lacks the required uv, Bun, Playwright, and uvicorn dependencies, or if your testing needs do not involve visual verification of FastAPI and Svelte catalog interfaces.
