如何使用rspec來測試正在救援和重定向的路線？

Question

我試圖寫一些快速路由測試一個簡單的API，所以我寫道：

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"} 

我很快就意識到我是從404搶救，所以幾乎一切是可路由的。

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 

這給我留下了這樣一個測試：

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

寫這樣很容易出錯，我爲我不斷得到「：A =>」錯誤的。有什麼方法可以測試一個異常是否被救出？

這工作：

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

...但什麼樣的錯誤，我應該檢查？或者我應該把它留在那？

你可以改變你的救援。變化：

unless Rails.env.development? 

到：

if Rails.env.production? 

這應該離開ENV測試出你的rescue404行爲。
