ruby-on-rails - 在 rspec 中找不到 Font-awesome-rails 助手

Question

我在使用 rspec 测试另一个助手时遇到了使用字体很棒的 fa_icon 助手的问题。在应用程序中，帮助者中的帮助者按预期工作；但是，当我为使用 fa_icon 的助手运行我们的 rspec 测试时，它失败了。

这是助手功能的简化版本:

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

这是指出 fa_icon 是未定义方法的失败之一。

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)>'

我是否需要以某种特殊方式在规范支持文件中包含 font-awesome-rails？我已将它包含在所有环境中的 Gemfile 中。

rspec 人员能够解决我的问题:

https://github.com/rspec/rspec-rails/issues/1007#issuecomment-41510827

require 'spec_helper'

describe ApplicationHelper do

  describe "#risk_flag" do
    context "with risk level below 3" do
      it "generates a smile icon" do
        expect(helper.risk_flag(2)).to eq("<i class=\"fa fa-smile-o\"></i>")
      end
    end
  end

end

主要的变化是我需要从 helper

中调用我的助手
