Write your UI tests
once. Run them anywhere.

import { createTestEngine } from '@atomic-testing/react-19';
import { HTMLButtonDriver, HTMLComponentDriver } from '@atomic-testing/component-driver-html';
import { byDataTestId } from '@atomic-testing/core';

// One scene definition — reused on every runtime
const scene = {
  greeting: { locator: byDataTestId('greeting'),   driver: HTMLComponentDriver },
  button:   { locator: byDataTestId('welcome-btn'), driver: HTMLButtonDriver },
};

it('welcomes the user on click', async () => {
  const engine = createTestEngine(<Welcome name="Alice" />, scene);

  expect(await engine.parts.greeting.getText()).toBe('Hello Alice!');
  await engine.parts.button.click();
  expect(await engine.parts.button.getText()).toBe('Welcome!');

  await engine.cleanUp();
});
