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应用编写请求规范，但文档稀疏（或者我只是还没有找到正确的文档）。

我有一个companies资源，其中包含大多数常用的API端点：

# 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

我希望我的规范指出，如果您在未登录时碰到这些端点，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”的方法。

具体来说， relishapp.com上的请求规范场景显示了在POST请求中使用了params选项哈希，我想知道此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"} }
    ...

您无需在请求方法中指定整个URL。 Rspec提供了一种更简短的方法，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

同样，您可以通过以下方式重写您上面提到的（发布，新建，索引）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)
