Feature: Linking of places
    Tests for correctly determining linked places

    Scenario: Only address-describing places can be linked
        Given the scene way-area-with-center
        And the place areas
         | osm_type | osm_id | class   | type   | name  | geometry
         | R        | 13     | landuse | forest | Garbo | :area
        And the place nodes
         | osm_id | class   | type | name  | geometry
         | 256    | natural | peak | Garbo | :inner-C
        When importing
        Then table placex contains
         | object  | linked_place_id
         | R13     | None
         | N256    | None

    Scenario: Waterways are linked when in waterway relations
        Given the scene split-road
        And the place ways
         | osm_type | osm_id | class    | type  | name  | geometry
         | W        | 1      | waterway | river | Rhein | :w-2

         | R        | 23     | waterway | river | Limmat| :w-4a
        And the relations
         | id | members                          | tags
         | 13 | R23:tributary,W1,W2:main_stream  | 'type' : 'waterway'

         | W2     | R13
         | R13    | None
         | R23    | None
        When sending query "rhein"
        Then results contain
         | osm_type
         | R

    Scenario: Relations are not linked when in waterway relations
        Given the scene split-road
        And the place ways
         | osm_type | osm_id | class    | type  | name  | geometry
         | W        | 1      | waterway | river | Rhein | :w-2

         | R        | 1      | waterway | river | Rhein | :w-1 + :w-2 + :w-3
         | R        | 2      | waterway | river | Limmat| :w-4a
        And the relations
         | id | members                          | tags
         | 1  | R2                               | 'type' : 'waterway'

         | W2     | None
         | R1     | None
         | R2     | None

    Scenario: Empty waterway relations are handled correctly
        Given the scene split-road

        Then table placex contains
         | object | linked_place_id
         | R1     | None

    Scenario: Waterways are not linked when waterway types don't match
        Given the scene split-road
        And the place ways

        When sending query "rhein"
        Then results contain
          | ID | osm_type
          |  0 | R
          |  1 | W

    Scenario: Side streams are linked only when they have the same name
        Given the scene split-road
        And the place ways
         | osm_type | osm_id | class    | type  | name   | geometry
