I'm trying to test a rake task and it uses an active record in it.

require 'spec_helper'
require 'rake'

load File.join(Rails.root, 'lib', 'tasks', 'survey.rake')

describe "survey rake tasks" do
  describe "survey:send_report" do
    it "should send a report" do
      Rake::Task['survey:send_report'].invoke
    end
  end
end

When I run this spec rspec spec/lib/survey_spec.rb, I get this error "

RuntimeError:
   Don't know how to build task 'environment'

How do I load the :enviroment task inside by example spec?

ruby-on-rails ruby rspec
