ruby-on-rails - 如何测试rspec中的路由错误？

Question

我通过删除 show 操作来简化资源，因为它不需要。只需要列出、创建和编辑。我的 rspecs 中仍然有我的 SHOW 测试，它现在失败了(很明显，因为我已经添加了一个 :except => [:show] 到我的路由文件。

这就是我失败的结果:

1) CampaignsController GET show assigns the requested campaign as @campaign
     Failure/Error: get :show, {:id => campaign.to_param}, valid_session
     ActionController::RoutingError:
       No route matches {:id=>"458", :controller=>"campaigns", :action=>"show"}
     # ./spec/controllers/campaigns_controller_spec.rb:49:in `block (3 levels) in <top (required)>'

  2) CampaignsController routing routes to #show
     Failure/Error: expect(:get => "/campaigns/1").to route_to("campaigns#show", :id => "1")
       No route matches "/campaigns/1"
     # ./spec/routing/campaigns_routing_spec.rb:15:in `block (3 levels) in <top (required)>'

我怎样才能让这些测试通过，以便我预期路由错误？

Answer 1

你可以做

expect{ get :show }.to raise_error(ActionController::RoutingError)

参见 https://www.relishapp.com/rspec/rspec-expectations/v/2-0/docs/matchers/expect-error

您还可以考虑路由规范:https://www.relishapp.com/rspec/rspec-rails/v/2-4/docs/routing-specs
