rspec单元测试

Question

当我用RSpec启动单元测试$ bundle exec rspec spec/时...

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
re': cannot load such file -- spec_helper (LoadError)

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

Answer 1

首先：

rails g rspec:install

它将创建文件spec_helper。

然后您就可以为测试准备数据库了：

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