Question

我已经编写了一个测试404页面的测试

pages_controller_spec.rb

RSpec.describe PagesController, type: :controller do
  before :all do
    Rails.application.config.action_dispatch.show_exceptions = true
    Rails.application.config.consider_all_request_local = false
  end

  describe "status 404" do
    it "respond with 404 if page is not found" do
      get :help, params: { id: "foobar" }
      expect(response.status).to eq(404)
    end
  end
end

页面控制器很简单，可以呈现静态页面“ / help”和“ / about”

class PagesController < ApplicationController
  def help
  end

  def about
  end
end

错误处理设置如下

application_controller.rb

 def not_found
   raise ActionController::RoutingError.new("Not Found")
 rescue
   render_404
 end

 def render_404
   render file: "#{Rails.root}/public/404", status: :not_found
 end

测试结果是

expected: 404
            got: 200

我不理解，因为当我在浏览器中亲自尝试时，“ / help / foobar”确实呈现了404页面。我想问题可能出在测试中我的“获取”操作格式错误，但我不确定。

config / routes.rb 根据要求

  get "/about", to: "pages#about"
  get "/help", to: "pages#help"

使用https://relishapp.com/rspec/rspec-rails/v/3-4/docs/routing-specs/route-to-matcher

中的语法更新了测试

测试现在看起来像这样

RSpec.describe PagesController, type: :controller do
  before :all do
    Rails.application.config.action_dispatch.show_exceptions = true
    Rails.application.config.consider_all_request_local = false
  end

  describe "status 404" do
    it "respond with 404 if page is not found" do
      expect(get("/foobar")).to route_to("application#not_found")
    end
  end
end

不幸的是，这引发了另一个错误

ActionController::UrlGenerationError:
 No route matches {:action=>"/foobar", :controller=>"pages"}

没有路线匹配，这很重要，但是出于某种原因使用了“ not_found”方法

更改路线以使您的通话可以从浏览器进行：

get "/help/:id", to: "pages#help"

如果测试返回200，那是因为它直接从您的控制器调用了help方法，而没有使用config/routes.rb文件。

以下是测试路由的方法：https://relishapp.com/rspec/rspec-rails/v/3-4/docs/routing-specs/route-to-matcher

RSpec 404测试响应状态为200
