  3) User 
     Failure/Error: it { should validate_format_of(:email).to_allow('[email protected]').not_to_allow('b!o^[email protected]') }
       Expected User to validate format of "email" allowing the value "[email protected]" and  not allowing the value "b!o^[email protected]"; instead got "format" validator on "email" with "b!o^[email protected]" as a valid value
