Testing DOM Interactions

Test UI code

Jest provides a simulated DOM via jsdom:

test('button click updates text', () => {
  document.body.innerHTML = '<button id="btn">Click</button>';
  
  const btn = document.getElementById('btn');
  btn.addEventListener('click', () => btn.textContent = 'Clicked');
  
  btn.click();
  
  expect(btn.textContent).toBe('Clicked');
});
