unit testing - Rails test - error with routing -

i have strange problem.

when run rake test, following wrror:

  1) error: streamscontrollertest#test_should_get_index: runtimeerror: in order use #url_for, must include routing helpers explicitly. instance, `include rails.application.routes.url_helpers      test/controllers/streams_controller_test.rb:5:in `block in <class:streamscontrollertest>' 

i added following code /test/test_helper.rb:

include rails.application.routes.url_helpers default_url_options[:host] = configurable[:server_host_name] default_url_options[:protocol] = configurable[:server_protocol] 

but still same error.

inside test class, sure, added debugging message:

require 'test_helper'  class streamscontrollertest < actioncontroller::testcase   test "should index"     puts ">>>> #{streams_url} <<<<"      :index     assert_response :success   end  end 

and expected url:

>>>> http://testing-end.com/streams <<<< 

btw, if change get :index get :index2 (which not exist) error:

  1) error: streamscontrollertest#test_non_existing_action: actioncontroller::urlgenerationerror: no route matches {:action=>"index2", :controller=>"streams"}     test/controllers/streams_controller_test.rb:11:in `block in <class:streamscontrollertest>' 

(which looks reasonable me)

some idea going on here??

================= update ==================

in integration test file able access pages using routes, example:

require 'test_helper'  class cacheflowstest < actiondispatch::integrationtest   test "should index"     root_url     assert_response :success   end 

but - when execution reaches route inside browsed code breaks:

  1) error: cacheflowstest#test_should_get_index: actionview::template::error: arguments passed url_for can't handled. please require routes or provide own implementation     app/views/streams/index.html.erb:51:in `block in _app_views_streams_index_html_erb__1226577901840473982_74088540' app/views/streams/index.html.erb:38:in `_app_views_streams_index_html_erb__1226577901840473982_74088540' test/integration/cache_flows_test.rb:5:in `block in <class:cacheflowstest>' 

i hope information understanding going on.
