Changing a button

General =

  • a changed button has to pass the check list from Adding a button. Depending on your change you only have to test part of the list. E.g. Just renaming the button needs a test whether the button still has a textual representation and that the text is still unique, but you don't need whether it is navigable by keyboard.

Check list

  • When changing caption is the changed text still unique
  • When changing the image is the alt tag still correct?
  • When changing the action behind the button: Can it still triggered by keyboard, mouse and speech recognition?
  • When changing font or color: Does the button still pass the contrast and sizing recommendations?
  • When reordering the buttons: Is keyboard navigation still semantically OK?
