ApplicationController中：
class ApplicationController < ActionController::Base before_filter :authenticate_user! protect_from_forgery end
DashboardsController：
class DashboardsController < ApplicationController def index end end
DashboardsControllerSpec：
require 'spec_helper'
describe DashboardsController do
include Devise::TestHelpers
describe "GET 'index'" do
it "returns http success" do
get 'index'
response.should be_success
end
end
end
结果：
Failure/Error: get 'index'
NoMethodError:
undefined method `authenticate_user!' for #<DashboardsController:0x007fef81f2efb8>
Rails版本：3.1.3
Rspec版本：2.8.0
设计版本：1.5.3
注意：我还创建了support / deviser.rb文件,但这没有帮助.有任何想法吗？
解决方法
require 'spec_helper'
describe DashboardsController do
before { controller.stub(:authenticate_user!).and_return true }
describe "GET 'index'" do
it "returns http success" do
get 'index'
response.should be_success
end
end
end
更新：
使用上述语法和最新的rspec将给出以下警告
Using `stub` from rspec-mocks' old `:should` Syntax without explicitly enabling the Syntax is deprecated. Use the new `:expect` Syntax or explicitly enable `:should` instead. Called from `block (2 levels) in <top (required)>'.
使用这种新语法
before do
allow(controller).to receive(:authenticate_user!).and_return(true)
end
