Selector tips

Good

  • [data-test-id='iframe-dynamic-height-primary']
  • [data-test-id='iframe-dynamic-height-secondary']
  • [data-test-id='iframe-dynamic-height-action']
  • [aria-label='iFrame Dynamic Height']
  • getByRole('button', { name: 'Height' })

Fallback

  • section.iframe-dynamic-height-container :nth-of-type(1)
  • .card.iframe_dynamic_height button:nth-of-type(1)
  • form.iframe-dynamic-height-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

  • Some parts delay render
  • Icon buttons need aria-label
  • Layout classes may shift
