当我使用 RSpec 开始单元测试 $ bundle exec rspec spec/...

admin@ADMINPC /d/ruby/rails/projects/CMS (static-pages)
$ bundle exec rspec spec/
d:/ruby/rails/projects/CMS/spec/controllers/pages_controller_spec.rb:1:in `requi

1.1/lib/rspec/core/runner.rb:8:in `block in autorun'

如何解决这个问题？

文件 pages_controller_spec.rb：

require 'spec_helper'

describe PagesController do

  describe "GET 'home'" do
    it "returns http success" do
      get 'home'
      response.should be_success
    end
  end

  describe "GET 'contact'" do
    it "returns http success" do
      get 'contact'
      response.should be_success
    end
  end

end

【解决方案1】：

首先：

rails g rspec:install

它将创建文件spec_helper。

然后你可以准备数据库进行测试：

rake db:test:load
rake db:test:prepare

我遇到了与此问题中所述类似的问题，但我没有意识到我需要执行您在此处描述的安装和 rake。谢谢！
