  # We decorete the core object with the current result.
  # In the first Before hook of a scenario, this will be an
  # instance of `Cucumber::Core::Test::Result::Unknown`
  # but as the scenario runs, it will be updated to reflect
  # the passed / failed / undefined / skipped status of
  # the test case.
