ruby-on-rails-3 - 我如何使用 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

但是我收到了:

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 中解救出来，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

这让我可以进行测试:

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

用这种方式写对我来说很容易出错，因为我经常把 ':a =>' 弄错。有什么方法可以测试是否正在挽救异常？

这个有效:

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

...但是我应该检查什么错误？还是我应该就此打住？

你可以改变你的救援。变化:

unless Rails.env.development?

到:

if Rails.env.production?

这应该将测试环境排除在您的 rescue404 行为之外。
