How to configure 'config.raise_errors_for_deprecations!'

There is a message showing up every time when I'm doing the rspec test on terminal,

"If you need more of the backtrace for any of these deprecations to identify where to make the necessary changes, you can configure config.raise_errors_for_deprecations!, and it will turn the deprecation warnings into errors, giving you the full backtrace."

I tried to add 'config.raise_errors_for_deprecations!', there is an error. I tried 'config.raise_errors_for_deprecations = true' and 'config.active_support.deprecation = :raise' still not solve the problem.

Hey Shan Lin that is a message with RSpec 3. The config line belongs in the Rspec.configure do |config| block in your rails_helper.rb (spec_helper.rb replacement) file.
