spect}, doesn't contain any alpha characters, so using it to
ase-sensitivity part of the validation is ineffective. There are
le solutions for this depending on what you're trying to do here:
meant for the validation to be case-sensitive, then you need to give
queness matcher a saved instance of #{model.name} with a value for
ibute} that contains alpha characters.
meant for the validation to be case-insensitive, then you need to
se_sensitive: false` to the validation and add `case_insensitive` to
cher.
