RSpec错误"未定义的方法`respond_with'..."

Question

我正在按照教程http://apionrails.icalialabs.com/book/chapter_three 但是当我运行控制器测试时,bundle exec rspec spec/controllers我得到了未定义的方法错误:

Failures:

 Api::V1::UsersController GET #show 
 Failure/Error: it { should respond_with 200 }
 NoMethodError:
   undefined method `respond_with' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x00000005d6f650>
 # ./spec/controllers/api/v1/users_controller_spec.rb:17:in `block (3 levels) in <top (required)>'

 Finished in 0.08435 seconds
 2 examples, 1 failure

请帮忙

编辑:以下是我的spec文件的内容

users_controller_spec.rb

require 'spec_helper'

describe Api::V1::UsersController do
  before(:each) { request.headers['Accept'] = "application/vnd.marketplace.v1" }

  describe "GET #show" do
    before(:each) do
      @user = FactoryGirl.create :user
      get :show, id: @user.id, format: :json
    end

    it "returns the information about a reporter on a hash" do
      user_response = JSON.parse(response.body, symbolize_names: true)
      expect(user_response[:email]).to eql @user.email
    end

    it { should respond_with 200 }
  end
end

Answer 1

由于我们正在与response codes您打交道，因此您可以在这里使用-

it { expect(response).to have_http_status(200) }

代替 it { should respond_with 200 }

这里也不需要shoulda-matchers宝石。

参考-https: //www.relishapp.com/rspec/rspec-rails/docs/controller-specs

Answer 2

我有同样的问题并解决了它.看起来像使用旧版本的shoulda-matchers有帮助.我改变了Gemfile对gem "shoulda-matchers", "~>2.5"

Answer 3

这似乎是shoulda-matchers gem的错误，尝试更新到最新版本。

还要确保它位于 gemfile 中的 RSpec 之后

group :development, :test do
  gem 'rspec-rails'
  gem 'shoulda-matchers'
end
