Question

我有一个像这样的块：

begin
  response = Facebook.make_profile_request(params[:token])
rescue => e
  Airbrake.notify(
     :error_class => "Facebook Processing",
     :error_message => "Error: #{e.message}"
   )

  flash[:notice] = "Uh oh...something went wrong. Please try again."
  redirect_to root_path
end

这是我到目前为止所做的：

it "should notify Airbrake if call to FB fails" do
  Facebook.stub(:make_profile_request).with(fb_token).and_raise(Exception)
  Airbrake.should_receive(:notify)
  get :facebook_process, token: fb_token
end

我收到错误：

  1) UsersController GET facebook_process should notify Airbrake if call to FB fails
 Failure/Error: get :facebook_process, token: fb_token
 Exception:
   Exception
 # ./app/controllers/users_controller.rb:9:in `facebook_process'
 # ./spec/controllers/users_controller_spec.rb:41:in `block (3 levels) in <top (required)>'

我该如何正确测试救援？

Answer 1

您必须指定一个特定的异常类，否则rspec会在检测到异常后立即保释;但是，如果没有从Exception中拯救，你可以做到这一点（正如Nick的评论所指出的那样）。

class MyCustomError < StandardError; end

begin
  response = Facebook.make_profile_request(params[:token])
rescue MyCustomError => e
  ...
end

在您的规范中，您应该使存根返回自定义错误类。像这样：

Facebook.stub(:make_profile_request).with(fb_token).and_raise(MyCustomError)

Answer 2

我最近遇到过类似的问题。

如果您更改了代码

rescue => e

到

rescue Exception => e

您的测试用例将通过。
