# Helper for enabling admin mode in tests

module AdminModeHelper
  # Administrators are logged in by default in user mode and have to switch to admin
  # mode for accessing any administrative functionality. This helper lets a user
  # access the admin area in two different ways:
  #
  # * Fast (use_ui: false) and suitable form the most use cases: fakes calls and grants
  # access to the admin area without requiring a second authentication step (provided the
  # user is an admin)
  # * Slow (use_ui: true): visits the admin UI and enters the users password. A second
  # authentication step may be needed.
  #
  # See also tag :enable_admin_mode in spec/spec_helper.rb for a spec-wide
  # alternative
