Defined in:
lib/eaco/cucumber/active_record/user/designators/user.rb

Overview

The simplest Designator. It resolves actors by their unique ID, such as an autoincrementing ID in a relational database.

The ID is available as the Designator#value. If the Designator is instantiated with a live instance (see Designator#initialize) then it is re-used and a query to the database is avoided.

The designator string representation for user 42 is “user:42”.
