Feature: template helpers

  Scenario: As a template developer, I want to get a Route Reference to the current route
    Given I am in any Twig template
      And I am in the master request
     When I use "{{ set route_reference = route_ref() }}"
     Then "route_reference" contains a Route Reference to the current route
  
  Scenario: As a template developer, I want to get a Route Reference to a location
    Given I am in any Twig template
      And "location" is a valid Location
     When I use "{{ set route_reference = route_ref( location ) }}"
     Then "root_reference" contains a Route Reference to "ez_content:view Location" for "location"
     
  Scenario: As a template developer, I want to get a link to a Route Reference
    Given I am in any Twig template
      And "route_reference" is a valid Route Reference
     When I use "{{ set path = path( route_reference ) }}"
     Then "path" contains the href for the Route Reference

  Scenario: As a template developer, I want to get a link to a Route Reference in a different language
    Given I am in any Twig template
      And "route_reference" is a valid Route Reference
     When I use "{{ set path = path( route_reference.set( lang, 'fre-FR' ) }}"
     Then "path" contains the href for the Route Reference in "fre-FR"

  Scenario: As a template developer, I can't get a link to the current route from a subrequest
    Given I am in any Twig template
      And I am in a sub request
     When I use "{{ route_ref() }}"
     Then I expect an exception to be thrown
