ruby on rails 5 - By filling in the code marked FILL_IN in Listing 3.42, write a test for the root route -

-

adding root route in listing 3.41 leads creation of rails helper called root_url (in analogy helpers static_pages_home_url). filling in code marked fill_in in listing 3.42, write test root route.

listing 3.41: setting root route home page. config/routes.rb  rails.application.routes.draw   root 'static_pages#home' end  listing 3.42: test root route. green test/controllers/static_pages_controller_test.rb  require 'test_helper'  class staticpagescontrollertest < actiondispatch::integrationtest    test "should root"     fill_in     assert_response fill_in   end end

what should fill_in? tried static_pages_root_url, root_url.

rails test fails. f  failure: staticpagescontrollertest#test_should_get_root [/home/ubuntu/workspace/sample_app/test/controllers/static_pages_controller_test.rb:12]: <root | ruby on rails tutorial sample app> expected <home | ruby on rails tutorial sample app>.. expected 0 >= 1.  e  error: staticpagescontrollertest#test_should_get_root: argumenterror: invalid response name: root_url     test/controllers/static_pages_controller_test.rb:11:in `block in <class:staticpagescontrollertest>'

try with:

  test "should root"     '/'     assert_response :success   end
