在Rails 3.1.0.rc6 / RSpec 2.6.0中,我正在尝试测试我的’产品’资源的路由,如下所示：

resources :products,:except => [:edit,:update]

有效操作的路由有效,但我想确保编辑和更新路由不可调用.这是我正在尝试的：

it "does not route to #edit" do
  lambda { get("/products/1/edit") }.should raise_error
end

Failure/Error: lambda { get(“/products/1/edit”) }.should raise_error
expected Exception but nothing was raised
# ./spec/routing/products_routing_spec.rb:11:in `block (3 levels)
in ‘

……然而,当我跑的时候

it "does not route to #edit" do
  get("/products/1/edit").should_not route_to("products#edit",:id => "1")
end

我明白了

Failure/Error: get(“/products/1/edit”).should_not
route_to(“products#edit”,:id => “1”)
ActionController::RoutingError:
No route matches “/products/1/edit”

知道这里发生了什么吗？我猜这应该很简单,但我似乎无法弄明白.
