在使用rspec测试另一个帮助程序时，我遇到使用字体awesome fa_icon帮助程序的问题。在应用程序中，帮助程序中的帮助程序按预期工作;但是，当我为使用fa_icon的帮助程序运行我们的rspec测试时，它会失败。
这是助手所做的简化版本：
def helper
if condition
fa_icon "some-icon"
else
fa_icon "some-other-icon"
end
end
这是一个失败，指出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)>'
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？我已经将它包含在所有环境中的Gemfile中。

rspec人能够解决我的问题：
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
