如何使用 rspec 来测试正在救援和重定向的路由？

Question

我试图为一个简单的 api 编写一些快速路由测试，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"}

我很快意识到我正在从 404 中拯救出来，所以几乎所有东西都是可路由的。

  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

这让我需要进行测试：以

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

这种方式编写对我来说很容易出错，因为我不断得到 ':a =>'错误的。有什么方法可以测试异常是否被拯救？

这有效：

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

...但是我应该检查什么错误？或者我应该就这样留下来吗？

你可以改变你的救援方式。更改

unless Rails.env.development?

为：

if Rails.env.production?

这应该将测试环境排除在你的rescue404行为之外。
