在 Rails 集成测试/RSpec 请求规范中指定 URL 参数

Question

我正在尝试为我正在构建的 Rails 应用程序编写请求规范，但文档很少（或者我还没有找到合适的文档）。

我有一个带有大多数常用 API 端点的 companies 资源：

# Routes -------------------------------------------------------------------
#    companies GET    /companies(.:format)          companies#index
#              POST   /companies(.:format)          companies#create
#  new_company GET    /companies/new(.:format)      companies#new
# edit_company GET    /companies/:id/edit(.:format) companies#edit
#      company GET    /companies/:id(.:format)      companies#show
#              DELETE /companies/:id(.:format)      companies#destroy
#              PATCH  /companies/:id(.:format)      companies#update

我希望我的规范表明，如果您在未登录时点击这些端点，它们会将您重定向到登录页面。对于前三个端点（没有:id 参数的端点），这很简单：

RSpec.describe 'Companies Endpoints', type: :request do    
  context 'with anonymous user' do
    it 'always redirects to sign-in page' do
      get '/companies'
      expect(response).to redirect_to(new_user_session_path)

      post '/companies'
      expect(response).to redirect_to(new_user_session_path)

      get '/companies/new'
      expect(response).to redirect_to(new_user_session_path)
  end
end

当端点包含 URL 参数 (get '/companies/:id/edit') 时，请求的语法是什么？到目前为止，这是我想出的：

RSpec.describe 'Companies Endpoints', type: :request do
  let :company { FactoryGirl.create(:company) }  # NOTE: this is new

  context 'with anonymous user' do
    it 'always redirects to sign-in page' do
      ...

      get "/companies/#{company.id}/edit"        # `company` is from the factory above
      expect(response).to redirect_to(new_user_session_path)

      ...
    end
  end

但我想知道这是否是“正确”的方式。

具体来说，the request spec scenarios on relishapp.com 显示使用 params 选项哈希作为 POST 请求的一部分，我想知道这个选项哈希是否也适用于 URL 参数？

RSpec.describe "Widget management", :type => :request do
  it "creates a Widget and redirects to the Widget's page" do
    post "/widgets", :params => { :widget => {:name => "My Widget"} }
    ...

您不需要在请求方法中指定整个 URL。 Rspec 提供了一种更短的方法，如下所述

RSpec.describe 'Companies Endpoints', type: :request do
  let :company { FactoryGirl.create(:company) }  # NOTE: this is new

  context 'with anonymous user' do
    it 'always redirects to sign-in page' do
      ...

      get :edit, { id: company.id }        # In this hash you can send any paramter, this will end up becoming your params for the request
      expect(response).to redirect_to(new_user_session_path)

      ...
    end
  end
end

也可以用以下方式重写您上面提到的 (post, new, index) 请求-

get :index
expect(response).to redirect_to(new_user_session_path)

post :create
expect(response).to redirect_to(new_user_session_path)

get :new
expect(response).to redirect_to(new_user_session_path)
