cucumber grails - feature with unimplemented steps still passes

Question

I have very recently started trying out BDD using cucumber and grails. I'm following a tutorial from the cucumber recipes book, and have created a feature but not yet created the step definitions to implement the test.

  Feature: Furious Fowl Game
    @integration
    Scenario: New Game
      Given: I see 3 buildings
      When: I slingshot a bird
      Then: I should see 2 buildings

When I run grails test-app :cucumber, I am expecting the test to fail to indicate that the steps have not been implemented, however the test result is success:

Furious Fowl Game
A single test executed without a single error or failure! 
System output

Feature: Furious Fowl Game
  Scenario: New Game # Game.feature:4
    Given: I see 3 buildings
    When: I slingshot a bird
    Then: I should see 2 buildings

I'm sure this is probably something obvious, but I'm stumped. Please let me know if you need to see anything I've not included above.

Looks like this was just down to the version of the grails cucumber plugin.

According to the changelog for the plugin 0.7.0 adds handling pending steps and reports them as errors, so have updated to 0.8.0.
