users csv export feature test and implementation

Feature: Export Users as CSV

  Background:
    Given a user "User 1" with:
      | id   | 1             |
      | name | Alex Barnsley |
    And a user "User 2" with:
      | id   | 2             |
      | name | Phil Thompson |
    And a role "Authorized" with permissions:
      | User    | read |
    And user "User 1" belongs to role "Authorized"

  Scenario: Export users list as csv
    When I sign in as user "User 1"
    And I browse to users list
    Then I see "User 1"
    And I see "User 2"
    When I click "CSV"
    Then I download a CSV with content:
      | Id | Name          | Username | Sign in count | Failed attempts | Last sign in at | Password changed at | Locked at  | Created at | Updated at |
      | 1  | Alex Barnsley | User 1   | <INT>         | <INT>           | <ISO_DATE>      | <ISO_DATE>          | <EMPTY>    | <ISO_DATE> | <ISO_DATE> |
      | 2  | Phil Thompson | User 2   | <INT>         | <INT>           | <EMPTY>         | <ISO_DATE>          | <EMPTY>    | <ISO_DATE> | <ISO_DATE> |


csv do
    column :id
    column(:name) { |user| user.object.name }
    column(:username) { |user| user.object.username }
    column :sign_in_count
    column :last_sign_in_at
    column :failed_attempts
    column :password_changed_at
    column :locked_at
    column :updated_at

  end
