    Then I should see an inline error "can't be blank" for the following formtastic fields:
      | label          | within       |
      | Full Name      | .identity    |
      | Date of birth  | .identity    |
      | Gender         | .identity    |
      | Marital status | .citizenship |

    And I should see an inline error "Please indicate your citizenship status" for the formtastic field "Citizenship status"
    And I should see an inline error "Please indicate how many dependants you have" for the formtastic field "Number of dependants"
