Ruby on rails rspec中找不到字体帮助程序

在使用rspec测试另一个帮助程序时，我遇到了使用字体awesome

fa_图标

helper的问题。在应用程序中，助手中的助手按预期工作；但是，当我为使用

fa_图标的助手运行rspec测试时，它失败了

这是助手所做工作的简化版本：

def helper
  if condition
    fa_icon "some-icon"
  else
    fa_icon "some-other-icon"
  end
end

下面是一个故障，说明
fa_icon
是一个未定义的方法

Failures:

  1) ApplicationHelper#risk_flag risk level is below 3 
     Failure/Error: subject { risk_flag(risk_level) }
     NoMethodError:
       undefined method `fa_icon' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_4::Nested_1:0x000000081ed900>
     # ./app/helpers/application_helper.rb:84:in `risk_flag'
     # ./spec/helpers/application_helper_spec.rb:79:in `block (3 levels) in <top (required)>'
     # ./spec/helpers/application_helper_spec.rb:83:in `block (4 levels) in <top (required)>'

任何帮助都将不胜感激。谢谢大家!
 rspec的人能够解决我的问题：


require'spec\u helper'
描述ApplicationHelper要做什么
描述“#风险#标志”do
“风险等级低于3”的上下文
它“生成一个微笑图标”吗
expect（helper.risk_标志（2））到等式（“”）
结束
结束
结束
结束

主要的变化是我需要取消我的助手的工作，rspec的人能够解决我的问题：
