我如何为Railscast编写link_to_add_fields帮助程序的RSpec测试197

Question

我在Railscast espisode＃197中使用了有关如何添加动态输入字段的方法详细信息，但我不确定如何为其编写RSpec测试。建议？

def link_to_add_fields(name, f, association, path, *args) 
    new_object = f.object.class.reflect_on_association(association).klass.new 
    fields = f.semantic_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| 
    render(path + association.to_s.singularize + "_fields", :builder => builder) 
    end 
    link_to_function(name, "add_fields(this, \"#{association}\", \"#{escape_javascript(fields.html_safe)}\")", *args) 
end

查看rspec请求规范（或黄瓜），因为你试图测试某个函数的行为。这样你就不必关心方法的底层实现。
