在我的 rails 3.2.3 应用程序中，我有一个主题控制器，它被建模为资源。我想编写一个功能测试来验证 /topics 上的帖子是有效路线。这应该首先失败，然后我将添加代码来修复它。但是，我在路由测试中遇到错误，而不是失败。我在做什么错？（注意：如果我在 routes.rb 中修复路由，测试通过 - 只是不确定为什么我在测试中收到错误而不是失败）：

# topics_controller_test.rb

test 'route exists to create topic' do
  assert_routing({:path => '/topics', :method => 'post'} , { :controller => "topics", :action => "create"}, {}, {}, 'could not route to create topic')
end

# routes.rb

resources :topics, :only => [:new]

# terminal output

$ rake test:functionals
Run options:

# Running tests:

.....E.

创建routes.rb的路线与您的测试路线不同。如果你想路由到:create控制器中的动作，routes.rb你应该使用：

resources :topics, :only => [:create]

请参阅 RailsGuides 中的路由主题。
