ruby-on-rails - Rspec:在辅助测试中设置 cookie

Question

辅助方法

  # Determine if this is user's first time
  def first_time?
    cookies[:first_time].nil?
  end

尝试 Rspec 测试

it "returns true if the cookie is set" do
  cookies[:first_time] = "something"
  helper.first_time?().should be(true)
end

错误:

undefined method `cookies' for nil:NilClass

我读过的关于 Rspec 和 cookie 的所有内容都与 Controller 有关。在 Rspec 辅助测试中获取/设置 cookie 的任何方法？

(Rspec/Rspec-rails 2.5, Rails 3.0.4)

谢谢!!

更新:

找到了关于如何设置 cookie 的答案，所以我将其留在这里以供其他人引用。

我正在寻找的作品:

helper.request.cookies[:awesome] = "something"

仍然不知道如何获取cookie...

我能找到的最好的解释在这里:https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs/cookies

引:

Recommended guidelines for rails-3.0.0 to 3.1.0

• Access cookies through the request and response objects in the spec.
• Use request.cookies before the action to set up state.
• Use response.cookies after the action to specify outcomes.
• Use the cookies object in the controller action.
• Use String keys.

例子:

# spec
request.cookies['foo'] = 'bar'
get :some_action
response.cookies['foo'].should eq('modified bar')

# controller
def some_action
  cookies['foo'] = "modified #{cookies['foo']}"
end
