Ruby on rails 服务对象方法打破集成测试Rails 4.2

我有一个Rails 4.2的集成测试，它在没有服务对象方法的情况下工作，但是当我试图将一些逻辑考虑到服务对象中时出现了一个错误。错误为“NameError:未初始化的常量LeadsController:：SendEmailConfirmation”

这适用于测试：

def create
  @lead = Lead.new(lead_params)
  if @lead.save
    LeadMailer.email_confirmation(@lead).deliver_now
    flash[:success] = "Thank you for subscribing"
    redirect_to root_path
  else
    render 'new'
  end
end

def create
  @lead = Lead.new(lead_params)
  if @lead.save
    SendEmailConfirmation.call(@lead) # This is the problem method
    flash[:success] = "Thank you for subscribing!"
    redirect_to root_path
  else
    render 'new'
  end
end

这不适用于测试：

def create
  @lead = Lead.new(lead_params)
  if @lead.save
    LeadMailer.email_confirmation(@lead).deliver_now
    flash[:success] = "Thank you for subscribing"
    redirect_to root_path
  else
    render 'new'
  end
end

def create
  @lead = Lead.new(lead_params)
  if @lead.save
    SendEmailConfirmation.call(@lead) # This is the problem method
    flash[:success] = "Thank you for subscribing!"
    redirect_to root_path
  else
    render 'new'
  end
end

发送电子邮件\u confirmation.rb：

class SendEmailConfirmation

  def self.call(lead)
    LeadMailer.email_confirmation(lead).deliver_now
    lead.confirmation_sent_at = Time.zone.now
    lead.save
  end

end

似乎服务对象本身可以工作，但测试无法识别该方法

关于我缺少的内容有什么想法吗？

当您为服务对象指定绝对名称空间时，它应该可以工作

::SendEmailConfirmation.call(@lead) # Note the "::"
