Testing

Current state

Testing is minimal. The project uses Jest via Create React App:

npm test

Runs react-scripts test in watch mode.

Existing tests

File	Coverage
`src/pages/Skeleton.test.js`	Smoke render of `Skeleton`

Dependencies: @testing-library/jest-dom, @testing-library/user-event.

Jest config

CRA overrides live in config/jest/babelTransform.js and fileTransform.js. There is no setupTests.js in the repo today.

Adding tests

Colocate tests as Component.test.js next to the component, or under src/pages/ for page shells.
Import from @testing-library/react and @testing-library/user-event.
Mock heavy dependencies:
- aws-amplify / Auth for auth flows
- fetch for API calls
- @abstractplay/gameslib / @abstractplay/renderer for game components

Example pattern:

import { render, screen } from "@testing-library/react";
import MyComponent from "./MyComponent";

test("renders heading", () => {
  render(<MyComponent />);
  expect(screen.getByText(/expected/i)).toBeInTheDocument();
});

What to prioritize

High-value test targets if expanding coverage:

callAuthApi — token missing, 401 redirect
botApi.js — response envelope parsing
Pure functions in src/lib/GameMove/ — exploration, settings
Route smoke tests for critical pages

Linting

ESLint config: .eslintrc.json (eslint:recommended, react-app, react-hooks).
