Rails 3 集成测试失败，简单 html 请求的 406 响应

Question

我有一个集成测试，向“显示”操作发送一个简单的 GET 请求。当我 assert_response :success 时我得到一个，它失败了，因为响应是 406，这意味着格式是 Not Acceptable HTTP。

require 'test_helper'

class UserFlowsTest < ActionDispatch::IntegrationTest
  fixtures :continents, :countries, :types

  test "browse register order" do
    docs = make_docs
    assert_equal Doc.count, docs.length, "Docs not created properly"
    bob=new_session_as(:bob)
    bob.goes_to_home
    bob.goes_to_doc(1)
  end

  private

  module TestDSL
    def goes_to_home
      get root_url
      test_results("docs/index")
    end

    def goes_to_doc(id)
      get docs_url(id), #{:format => :html} - fails with this as well...
      y request.inspect
      p response.inspect
      test_results("docs/show")
    end

    def test_results(path)
      assert_response :success, "Checking #{path}"
      assert_template path
    end
  end #module TestDSL



  def new_session_as(person)
    new_session do |sess|
      #sess.goes_to_login
      #sess.logs_in_as(person)
      yield sess if block_given?
    end
  end

  def new_session
    open_session do |sess|
      sess.extend(TestDSL)
      yield sess if block_given?
    end
  end

end

这是 request.inspect 的输出：

“goes_to_home”测试按预期工作。在我的电脑上的开发环境中使用该页面也可以正常工作。这是服务器控制台输出：

有什么想法吗？ 提前致谢

Answer 1

这个问题是由于在“get”调用中使用了错误的路径造成的。

由于某种原因 docs_url(@doc) 生成“/docs.7”而不是“/docs/7”

我已经就这个话题开了separate question。
