如何使用rspec来测试正在救援和重定向的路线？

Question

我试图写一些快速路由测试一个简单的API，所以我写道：

it "delete" do 
    delete("/api/notifications/:id").should_not be_routable 
    end 

但我收到：

Failure/Error: delete("/api/notifications/:id").should_not be_routable 
    expected {:delete=>"/api/notifications/:id"} not to be routable, but it routes to {:controller=>"application", :action=>"rescue404", :a=>"api/notifications/:id"} 

我很快就意识到我是从404抢救，所以几乎一切是可路由的。

unless Rails.env.development? 
    rescue_from NotFound, :with => :rescue404 
    rescue_from ActiveRecord::RecordNotFound, :with => :rescue404 
    rescue_from ActionController::RoutingError, :with => :rescue404 
    end 

    def rescue404 
    respond_to do |format| 
     format.json { render :text => 'Something went wrong. Record not found or url is incorrect.\n' } 
     format.xml { render :text => 'Something went wrong. Record not found or url is incorrect.\n' } 
     format.html { redirect_to root_url, :alert => 'That page does not exist, sorry bro!' } 
    end 
    end 

这给我留下了这样一个测试：

it "delete" do 
    delete("/api/notifications/:id").should route_to("application#rescue404", :a => "api/notifications/:id") 
    end 

写这样很容易出错，我为我不断得到“：A =>”错误的。有什么方法可以测试一个异常是否被救出？

这工作：

it "delete" do 
    delete("/api/notifications/:id").should raise_error() 
    end 

...但什么样的错误，我应该检查？或者我应该把它留在那？

你可以改变你的救援。变化：

unless Rails.env.development? 

到：

if Rails.env.production? 

这应该离开ENV测试出你的rescue404行为。
