# For testing rake tasks
require "rake"

# Task names should be used in the top-level describe, with an optional
# "rake "-prefix for better documentation. Both of these will work:
#
# 1) describe "foo:bar" do ... end
#
# 2) describe "rake foo:bar" do ... end
#
# Favor including "rake "-prefix as in the 2nd example above as it produces
# doc output that makes it clear a rake task is under test and how it is
# invoked.
