ruby-on-rails - rspec 输出中的 rails omniauth 错误

Question

我有一个使用 devise/omniauth 允许通过 facebook 登录的 Rails 4 应用程序。该应用程序似乎有效，测试似乎也有效。但是我有一个测试来检查用户通过 facebook 登录但决定不授予权限的情况。

此测试工作正常，但会向 rspec 输出发送一条错误消息

$ rspec -fd --tag inspect 
Sign in with facebook
  new user
E, [2013-10-20T21:25:24.232573 #17137] ERROR -- omniauth: (facebook) Authentication failure! invalid_credentials encountered
    does not grant permission

Finished in 0.21152 seconds
1 example, 0 failures

或

$ rspec 
....E, [2013-10-20T21:25:24.232573 #17137] ERROR -- omniauth: (facebook) Authentication failure! invalid_credentials encountered.

相关测试

require 'spec_helper.rb'

feature "sign in with facebook" do
  context "new user" do
    scenario "does not grant permission", inspect: true do
      dont_sign_in_with_facebook
      expect(notice_area).to have_content "Could not authenticate you from Facebook because \"Invalid credentials\""
    end
  end
end

和 authentication_helper

module Features
  module AuthenticationHelpers
    def dont_sign_in_with_facebook
      OmniAuth.config.test_mode = true
      OmniAuth.config.mock_auth[:facebook] = :invalid_credentials
      visit "/users/auth/facebook"
    end
  end
end

我可以做些什么来抑制 rspec 输出中的错误消息吗？

编辑

我尝试实现@Shepmaster 描述的静音功能，但没有解决问题。然后尝试从 rspec 命令重定向错误:

rspec -fd --tag inspect  2> /dev/null
Sign in with facebook
  new user
E, [2013-10-20T21:25:24.232573 #17137] ERROR -- omniauth: (facebook) Authentication failure! invalid_credentials encounterd
    does not grant permission

Finished in 0.21152 seconds
1 example, 0 failures

Randomised with seed 65190

并重定向标准输出

rspec -fd --tag inspect  > /dev/null

没有输出!

最后使用输出选项

rspec -fd --tag inspect -o /tmp/rspec.out 2> /dev/null
cat /tmp/rspec.out 

Sign in with facebook
  new user
    does not grant permission

Finished in 0.21152 seconds

回答使用@shepmaster 的答案

module Features
  module AuthenticationHelpers
    def dont_sign_in_with_facebook
      OmniAuth.config.test_mode = true
      OmniAuth.config.mock_auth[:facebook] = :invalid_credentials
      silence_omniauth {visit "/users/auth/facebook"}
    end
  end
end

我在 Rails 4.2 应用程序中遇到了同样的问题。解决方法是在初始化程序中将 OmniAuth 记录器设置为 Rails 记录器 per the README :

# config/initializers/omniauth.rb
OmniAuth.config.logger = Rails.logger
