Rspec: setting cookies in a helper test

问题

Helper Method

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

Attempted Rspec test

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

Error:

undefined method `cookies' for nil:NilClass

Everything I've read about Rspec and cookies has to do with the controller. Any way to get/set cookies in Rspec helper tests?

(Rspec/Rspec-rails 2.5, Rails 3.0.4)

Thanks!!

UPDATE:

Found an answer on how to SET cookies, so I'll leave it here for other's reference.

the piece I was looking for:

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

Still don't know how to GET cookies...

回答1:

The best explanation I've been able to find is here: https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs/cookies

Quoted:

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.

Example:

# 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

I just stumbled upon your question (I was looking for an answer). I tried this successfully:

helper.request.cookies[:foo] = "bar"

回答3:

You get the cookies the same way you set them. Example from one of my specs:

request.cookies[:email].should be nil

回答4:

In a controller test this works:

@request.cookies[:cookie_name] = "cookie_value"

in a before block.
