rspec rails mocking会话哈希

我试图像这样模拟控制器的会话哈希:

it "finds using the session[:company_id]" do
  session.should_receive(:[]).with(:company_id).and_return 100
  Company.should_receive(:find).with(100)
  get 'show'
end

当我打电话给'show'时,它说:

received :[] with unexpected arguments  
expected: (:company_id)  
   got: ("flash")

控制器代码如下所示:

def show
  company_id = session[:company_id]
  @company = Company.find params[company_id]
end

我也尝试过设置

it "finds using the session[:company_id]" do
  session[:company_id]= 100
  Company.should_receive(:find).with(100)
  get 'show'
end

但后来遇到了一个问题:

expected: (100)
got: (nil)

任何人都有想法的原因?

我刚碰到这个。我无法设法让miss_receive不干扰flash内容。

但这让我测试了我正在寻找的行为:

it "should redirect to intended_url if set" do
  request.env['warden'] = double(:authenticate! => true)
  session.stub(:[]).with("flash").and_return double(:sweep => true, :update => true, :[]= => [])
  session.stub(:[]).with(:intended_url).and_return("/users")
  post 'create'
  response.should redirect_to("/users")
end

希望有帮助...

我无法弄清楚如何模拟会话容器本身,但在大多数情况下,只需通过请求传递会话数据就足够了。因此测试将分为两种情况:

it "returns 404 if company_id is not in session" do
  get :show, {}, {}
  response.status.should == 404 # or assert_raises depending on how you handle 404s
end

it "finds using the session[:company_id]" do
  Company.should_receive(:find).with(100)
  get :show, {}, {:company_id => 100}
end

PS:忘了提及我正在使用this snippet中的一些自定义助手。

试试这个:

session.expects(:[]).with(has_entries('company_id' => 100))

这是因为您从控制器获取Flash会话。所以定义它。 Flash会在会话中保存。

it "finds using the session[:company_id]" do
  session.stub!(:[]).with(:flash)
  session.should_receive(:[]).with(:company_id).and_return 100
  Company.should_receive(:find).with(100)
  get 'show'
end
