Rspec无法连接服务器错误

Question

我正在与rspec一起测试rails应用程序，我的代码用于测试控制器，如下所示

require "spec_helper"
require "support/factory_girl"

RSpec.describe UsersController, :type => :controller do
  let(:user) { FactoryGirl.create(:user) }

  let(:other_user) { FactoryGirl.create(:user) }

  before { login user }

  describe "POST #follow" do
    it "adds that user to friends" do
      binding.pry
      post :follow, id: other_user, format: :js
      expect(response).to have_http_status(:ok)
      expect(user.following? other_user).to be_truthy
    end
  end

但是，这会导致连接失败错误，该错误为

UsersController POST #follow adds that user to friends
     Failure/Error: let(:user) { FactoryGirl.create(:user) }
     Faraday::ConnectionFailed:

在设置环境时，还有什么是我错过的吗？我不知道为什么会发生这种访问错误，因为我已经授予了以下附加的本地db访问的完全权限是完全错误消息

Faraday::ConnectionFailed:

Answer 1

从异常回溯跟踪来看，当试图连接到Elasticsearch时，似乎会引发错误。

在运行测试套件之前，确保您的elasticsearch服务器正在运行。

Answer 2

看起来您的测试试图连接到Elasticsearch服务器，但无法。您应该禁用您的测试环境的Elasticsearch，或者设置一个对您的测试环境有效的配置。
