Why consider_all_requests_local fails with rspec config

Question

rspec-rails (2.7.0) rails (3.0.10) post: Rails 3.1 Error Catching is irrelevant for me.

Code:

class ApplicationController < ActionController::Base

You also need to set Rails.application.config.action_dispatch.show_exceptions = true. But since Rails caches that value, this will only work if you run your spec on its own. Fortunately, you can change these options only for the current spec by mocking the config:

  before do
    method = Rails.application.method(:env_config)
    expect(Rails.application).to receive(:env_config).with(no_args) do
      method.call.merge(
        "action_dispatch.show_exceptions" => true,
        "action_dispatch.show_detailed_exceptions" => false,
        "consider_all_requests_local" => false
      )
    end
  end
