进行基本的辅助测试：

代码语言：javascript
复制
require 'rails_helper'

describe BuilderHelper do
  ...
  describe 'press events classes' do
    let(:account) { create(:candidate_profile).account }

    before { allow_any_instance_of(Object).to receive(:current_account).and_return account }

    specify do
      expect_any_instance_of(PublicPage).to receive(:show_press?).and_return true
      expect_any_instance_of(PublicPage).to receive(:show_events?).and_return true
      expect(press_events_classes(account)).to eq 'section'
    end
    ...
  end
  ...
end

它带来了奇怪的错误：

代码语言：javascript
复制
 Failure/Error: before { allow_any_instance_of(Object).to receive(:current_account).and_return account }
     NoMethodError:
       undefined method `unbind' for #<Proc:0x00000009803640>
     # ./spec/helpers/builder_helper_spec.rb:27:in `block (3 levels) in <top (required)>'
     # ./spec/support/vcr.rb:16:in `block (2 levels) in <top (required)>'
     (that's it, that's the whole error log)

因此，错误在before块中。问题是，我在任何地方都没有“解绑定”方法。我看了Rails回购-它似乎没有任何东西。不知道有什么问题。有人能帮我去哪里找吗？

好吧，感谢你的评论我得到了以下信息：

还是不知道该怎么做。

更新

解决办法是取代这一办法：

代码语言：javascript
复制
before { allow_any_instance_of(Object).to receive(:current_account).and_return account }

在这方面：

代码语言：javascript
复制
before { allow_any_instance_of(BuilderHelper).to receive(:current_account).and_return account }

因此，我最好的猜测，这是很难说出来的，但我所做的是，事实上，我删除了发现，并返回了一个proc对象的位置。

代码语言：javascript
复制
let(:record) { create :record } # This is a Proc
allow(Object).to receive(:find).and_return(record)
allow_any_instance_of(Object).to receive(:update) # This calls unbind

可悲的是，试图弄清楚第一个存根是在哪里发生的。但我敢打赌它就在你的密码里。
