Run `yarn test --prod` to test in the production environment. It supports the same options as `yarn test`. 6. If you need a debugger, run `yarn test --debug --watch TestName`, open `chrome://inspect`, and press "Inspect". 7. Format your code with [prettier](https://github.com/prettier/prettier) (`yarn prettier`). 8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only check changed files. 9.

What existing problem does the pull request solve? --> Added more tests for the compiler playground with the addition of the new config editor and "Show Internals" button.

React Compiler Playground
An interactive playground to demonstrate, test, and have fun with React Compiler.
Setup
# Build React Compiler from source and install Playground dependencies.
$ yarn
# Or similarly
$ npm install
Development
# Start the local development server with
$ yarn dev
# Or
$ npm run dev
# Rerun the following (in a separate terminal window) when React Compiler
# is changed locally to keep Playground in sync.
$ yarn
Testing
# Install playwright browser binaries
$ npx playwright install --with-deps
# Run tests
$ yarn test
Deployment
This project has been deployed using Vercel. Vercel does the exact same thing as we would
locally, by running yarn at the install step in the Playground directory to build
React Compiler from source and symlink it as its dependency.
This means that Playground is automatically deployed on every push and pull requests will reflect
the behaviors of React Compiler of that commit.
