ruby - Using Cookies with Rack::Test -

I am trying to write a RSPEC test for my signature application using Rack :: Test. I can not understand how I can use cookies. For example, if my application sets a cookie (not through session) how can I check whether the cookie is properly set or not?

In addition, how can I send a request with that cookie?

rack :: test maintains a cookie jar which persists on requests. You can access it from rack_mock_session.cookies Suppose you have a handler like this:

  Go '/ Cookie / Set'. Give Feedback.Setcupi "Foo" ,: Value => "Bar" end   
 Now you can test with something like this:  
  It defines a cookie '/' rack_mock_session. Cookie_jar ["foo"]. You can access the cookies with  last_request.cookies , but as the name implies, it contains cookies for the last request. For, no answer You can set cookies with  set_cookie  and clear them with  clear_cookies .  
  This shows how to set a cookie "What to do clear_cookies set_cookie" foo = Quux "get '/' last_request.cookies.should == {" foo "=>" Quux "} End   
  Update:  If you want to remain in test cases ( this  block) Before performing the cases, you need to start the rack session. To do this, before your  block  block  
  before Do: all clear_cookies end   
 Alternatively, you can use  before: each  to set the necessary cookies before each request.
