Testing

Testing stack including Playwright, Vitest, linting, formatting.

Playwright

We use Playwright for our End-to-End tests in this project. You'll find those in the tests directory. As you make changes, add to an existing file or create a new file in the tests directory to test your changes.

To run these tests in development, run npm run test:e2e:dev which will start the dev server for the app and run Playwright on it.

We have a fixture for testing authenticated features without having to go through the login flow:

test('my test', async ({ page, login }) => {
	const user = await login()
	// you are now logged in
})

We also auto-delete the user at the end of your test. That way, we can keep your local db clean and keep your tests isolated from one another.

Vitest

For lower level tests of utilities and individual components, we use vitest. We have DOM-specific assertion helpers via @testing-library/jest-dom.

Type Checking

This project uses TypeScript. It's recommended to get TypeScript set up for your editor to get a really great in-editor experience with type checking and auto-complete. To run type checking across the whole project, run npm run typecheck.

Linting

This project uses ESLint for linting. That is configured in .eslintrc.js.

Formatting

We use Prettier for auto-formatting in this project. It's recommended to install an editor plugin (like the VSCode Prettier plugin) to get auto-formatting on save. There's also a npm run format script you can run to format all files in the project.
