Do you write automated tests? Do you have experience writing tests?

Yes, I write automated tests and have experience in their development. Automated tests help ensure the stability and correctness of the code when changes are made.

In frontend development, I usually write:

• Unit tests for components and utilities using Jest, Mocha, or other frameworks.
• Integration tests to verify the interaction between components.
• E2E tests (for example, with Cypress or Playwright) to test user scenarios.

An example of a simple React unit test with Jest:

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

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

Automated tests help quickly identify regressions and improve product quality.
