Getting started with writing end-to-end tests with Playwright:
Initializing project in '.'
✔ Which framework do you use? (experimental) · react
✔ Install Playwright browsers (can be done manually via 'pnpm exec playwright install')? (Y/n) · true
✔ Install Playwright operating system dependencies (requires sudo / root - can be done manually via 'sudo pnpm exec playwright install-deps')? (y/N) · true

Installing Playwright Component Testing (pnpm add --save-dev @playwright/experimental-ct-react)…

ERR_PNPM_ADDING_TO_ROOT  Running this command will add the dependency to the workspace root, which might not be what you want - if you really meant it, make it explicit by running this command again with the -w flag (or --workspace-root). If you don't want to see this warning anymore, you may set the ignore-workspace-root-check setting to true.
