ruby-on-rails - rspec Rails 模拟 session 哈希

Question

我正在尝试模拟 Controller 的 session 哈希，如下所示:

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

当我调用 get 'show' 时，它指出:

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

Controller 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

但随后遇到了一个问题:

expected: (100)
got: (nil)

有人知道为什么吗？

Answer 1

我刚刚遇到了这个。我无法设法让 should_receive 不干扰 flash 的东西。

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...
