Feature: Comparability

  Scenario: Fail when comparing nodes to parameters
    Given an empty graph
    And having executed:
      """
      CREATE ()
      """
    And parameters are:
      | param | 'foo' |
    When executing query:
      """
      MATCH (b)
      WHERE b = $param
      RETURN b
      """
    Then a TypeError should be raised at compile time: IncomparableValues

  Scenario: Fail when comparing parameters to nodes
    Given an empty graph
    And having executed:
      """
      CREATE ()
      """
    And parameters are:
      | param | 'foo' |
    When executing query:
      """
      MATCH (b)
      WHERE $param = b
      RETURN b
      """
    Then a TypeError should be raised at compile time: IncomparableValues

  Scenario: Comparing nodes to properties
    Given an empty graph
    And having executed:
      """
      CREATE ({val: 17})
      """
    When executing query:
      """
      MATCH (a)
      WHERE a = a.val
      RETURN count(a)
      """
    Then a TypeError should be raised at compile time: IncomparableValues

  Scenario: Fail when comparing nodes to relationships
    Given an empty graph
    And having executed:
      """
      CREATE ()-[:T]->()
      """
    When executing query:
      """
      MATCH (a)-[b]->()
      RETURN a = b
      """
    Then a TypeError should be raised at compile time: IncomparableValues

  Scenario: Fail when comparing relationships to nodes
    Given an empty graph
    And having executed:
      """
      CREATE ()-[:T]->()
      """
    When executing query:
      """
      MATCH (a)-[b]->()

    Then a TypeError should be raised at compile time: IncomparableValues
