测试一条路线时,Rspec未定义方法`route_to'？

Question

我是Rspec的新手,我正在尝试在我的应用程序中测试一条路线.我已经安装了Rspec并且已经包含了路由文件spec/routing/routes_spec.rb.

我的规格如下:

require "spec_helper"

describe "Routes" do
  it "routes get index" do
    expect(:get => "simulations").to route_to(
      :controller => "simulations",
      :action => "index"
    )
  end
end

我收到此错误:

Routes routes get index
    Failure/Error: expect(:get => "simulations").to route_to(
    NoMethodError:
      undefined method `route_to' for #<RSpec::ExampleGroups::Routes:0x007fc32d2f70b8 @__memoized=nil>
    # ./spec/routing/routes_spec.rb:6:in `block (2 levels) in <top (required)>'

关于为什么route_to不明确的任何想法？我已经确认路线确实有效.

在Rspec 3中你应该require 'rails_helper'而不是require 'spec_helper'.
