Have resources been allocated for writing tests? What is your experience in writing tests?

Yes, resources were allocated in projects for writing tests, as it is critical for the maintainability and quality of frontend applications.

Experience in writing tests includes:

• Unit tests using Jest and React Testing Library to verify components and utilities.
• Integration tests to check interaction between modules.
• E2E tests with Cypress to simulate user scenarios.

For example, a unit test for a React component might look like this:

import { render, screen } from '@testing-library/react';
import Button from './Button';

test('renders a button with text', () => {
  render(<Button>Click me</Button>);
  expect(screen.getByText('Click me')).toBeInTheDocument();
});
