Selector tips

Good

  • [data-test-id='off-screen-element-secondary']
  • [data-test-id='off-screen-element-action']
  • [aria-label='Off-screen Element']
  • getByRole('button', { name: 'Off' })

Fallback

  • section.off-screen-element-container :nth-of-type(1)
  • .card.off_screen_element button:nth-of-type(1)
  • form.off-screen-element-form .field-group:nth-child(1)

Avoid

  • .mt-4.mb-2.flex.items-center > input:nth-child(1)
  • .css-1a2b3c4
  • div[class*='temp-'][class*='hover']

Notes
