如何在Rails測試環境中獲得完整的堆棧跟蹤，而不是“處理請求時發生意外錯誤”？

Question

在測試環境（ rails s -e test ）中啟動我的Rails服務器時，某些東西正在搶救異常並輸出“處理請求時出現意外錯誤：...此處錯誤...”。 我在開發模式中得到了回溯。

是誰，如何禁用它？ 我需要完整的回溯，而不僅僅是引發的錯誤！

我正在使用Rails 3.2.3，Ruby 1.9.3，rspec，capybara，capybara-webkit

Answer 1

在test.rb設置config.action_dispatch.show_exceptions = true對我test.rb 。

Answer 2

閱讀由Cucumber創建的env.rb ：

# By default, any exception happening in your Rails application will bubble up
# to Cucumber so that your scenario will fail. This is a different from how 
# your application behaves in the production environment, where an error page will 
# be rendered instead.
...
# 1) Tag your scenario (or feature) with @allow-rescue
# 2) Set the value below to true. Beware that doing this globally is not
# recommended as it will mask a lot of errors for you!

摘要：

@allow-rescue
Feature: blah blah blah

會成功的。
