对命令空间的控制器进行Rspec测试

Question

我正在使用'Api'命名空间，我想为我的控制器编写测试。但是，我无法让post方法为此工作。

我试过

describe Api::EnvsController do

    describe "POST create" do
        it "creates a new env" do
            expect { post :create, :env => { :name => "This_te" } }.to change(Env,:count).by(1)
        end
    end
end



describe EnvsController do

    describe "POST create" do
        it "creates a new env" do
            expect { post :create, :env => {:name => "mym"} }.to change(Env,:count).by(1) 
        end
    end
end

错误：

  4) Api::EnvsController POST create creates a new env
     Failure/Error: expect { post :create, :env => {:name => "mym"} }.to change(Env,:count).by(1)
     ActionController::UnknownFormat:
       ActionController::UnknownFormat
     # ./app/controllers/api/envs_controller.rb:5:in `create'
     # ./spec/controllers/api/envs_controller_spec.rb:7:in `block (4 levels) in <top (required)>'
     # ./spec/controllers/api/envs_controller_spec.rb:7:in `block (3 levels) in <top (required)>'

  5) EnvsController POST create creates a new env
     Failure/Error: expect { post :create, :env => {:name => "mym"} }.to change(Env,:count).by(1)
     ActionController::UrlGenerationError:
       No route matches {:env=>{:name=>"mym"}, :controller=>"envs", :action=>"create"}
     # ./spec/controllers/envs_controller_spec.rb:7:in `block (4 levels) in <top (required)>'
     # ./spec/controllers/envs_controller_spec.rb:7:in `block (3 levels) in <top (required)>'

这让我相信'post：create，：env =＆gt; ：name =＆gt; “string”} ......'工作不正常。虽然我已经尝试了基于RSpec的post方法的所有推导，但是这里有样本。

post "/widgets", :widget => {:name => "My Widget"}

当我改变它以满足我的需要时

expect { post "api/envs", :env => { :name => "This_te" } }.to change(Env,:count).by(1)

我收到一个url生成错误，说我没有匹配它的路由。 IE

  5) Api::EnvsController POST create creates a new env
     Failure/Error: expect { post "/api/envs", :env => { :name => "This_te" } }.to change(Env,:count).by(1)
     ActionController::UrlGenerationError:
       No route matches {:env=>{:name=>"This_te"}, :controller=>"api/envs", :action=>"/api/envs"}
     # ./spec/controllers/api/envs_controller_spec.rb:7:in `block (4 levels) in <top (required)>'
     # ./spec/controllers/api/envs_controller_spec.rb:7:in `block (3 levels) in <top (required)>'

根据要求从控制器创建。

  def create
    @env = Env.new(env_params)
    respond_to do |format|
      if @env.save
        format.json { render json: @env, status: :created }
      else
        format.json { render json: @env.errors, status: :unprocessable_entity }
      end
    end
  end
