如何在Rails 3.1可安装引擎中测试路由

test "should route to your_action" do
  assert_recognizes({:controller => "your_controller", :action => "your_action"}, {:path => "your_path", :method => :get})
end

test "should route to users#index" do
  assert_recognizes({:controller => "users", :action => "index"}, {:path => "/users", :method => :get})
end

test "should route to your_action with parameter" do
  assert_recognizes({:controller => "your_controller", :action => "your_action", :id => "1"}, {:path => "your_path/1", :method => :get})
end

test "should route to users#show with parameter" do
  assert_recognizes({:controller => "users", :action => "show", :id => "1"}, {:path => "/users/1", :method => :get})
end
