Svelte Testing

Quick Start

// Client-side component test (.svelte.test.ts)
import { render } from 'vitest-browser-svelte';
import { expect } from 'vitest';
import Button from './button.svelte';

test('button click increments counter', async () => {
	const { page } = render(Button);
	const button = page.getByRole('button', { name: /click me/i });

	await button.click();
	await expect.element(button).toHaveTextContent('Clicked: 1');
});
