Ruby on rails 检查第500页的测试用例&；404

我正在努力通过404和500页的测试用例。但是我有很多问题

1） 首先，我在app/views/errors/中有一个500.html.erb页面，没有被调用
2） 如果我运行以下测试，我的系统将冻结，需要重新启动系统
3） 如果我注释这一行请期待{get”/errors/foo}。引发_异常（ActionController:：RoutingError）。因此，在我的控制器操作名页面中，500作为参数传递，但我的系统仍然冻结

有人能帮我解决这个问题吗

错误\u spec.rb

 require "spec_helper"

    describe "Errors" do

      before do
        allow(Rails).to receive(:env).and_return(ActiveSupport::StringInquirer.new("production"))
      end

      it "renders the 500 page" do
         get "/errors/500"
         expect(response.status).to eq(500)
      end

      it "renders the 404 page" do
        get "/errors/404"
        expect(response.status).to eq(404)
      end

      it "raises an exception if the page doesn't exist" do
        expect {get "/errors/foo"}.to raise_exception(ActionController::RoutingError)
      end
    end

  skip_before_filter :authenticate_user!

  EXTERNAL_ERRORS = ['sso']
  VALID_ERRORS = ['404', '403', '500', 'maintenance'] + EXTERNAL_ERRORS

类错误控制器

在您的代码中，当调用/errors/500时，您正在设置状态200

  def show
    # external_error? returns false.
    status = external_error? ? 500 : 200
    render page , status: status # Status is 200.
  end

使用诸如

pry

或

byebug

之类的调试器检查状态。测试用例中没有任何问题。试试这个

class ErrorsController < ApplicationController
  skip_before_filter :authenticate_user!

  EXTERNAL_ERRORS = ['sso']
  VALID_ERRORS = ['404', '403', '500', 'maintenance'] + EXTERNAL_ERRORS

  def show
    status = error_500? ? 500 : 200
    render page , status: status
  end

  def blocked
  end

  private

  def page
    if VALID_ERRORS.include?(params[:id])
      params[:id]
    else
      raise(ActionController::RoutingError.new("/errors/#{params[:id]} not found"))
    end
  end

  def external_error?
    EXTERNAL_ERRORS.include?(params[:id])
  end

  def error_500?
    ['500'].include?(params[:id]) || external_error?
  end
end

这是一个仅测试的问题，即当您在浏览器中打开URL时，它是否工作？当我尝试从浏览器中点击时，它工作正常。您可以在测试中打开任何其他URL而不冻结系统吗，也就是说，问题是否特定于

错误控制器

？是的，我可以在错误控制器中打开除404和404之外的其他URL500@Stefan-你知道我哪里做错了吗？
