ruby-on-rails-4 – 使用rails 4和rspec 3通过verify_partial_do

我的主索引有一个非常简单的视图规范：

RSpec.describe "main/index.html.erb",:type => :view do
  context "when not logged in" do

    before do
      allow(view).to receive(:current_user).and_return(nil)
    end

    it "has an h1" do
      render
      expect(rendered).to include('h1')
    end

  end
end

问题是,如果我的配置中的“mocks.verify_partial_doubles = true”,那么这会导致一个令人印象深刻的大错误,因为它会转储整个对象然后在底部说：

1) main/index.html.erb when not logged in has an h1
     Failure/Error: allow(view).to receive(:current_user).and_return(nil)
       #<#<Class:0x00000104c249d0>:.........
       @rendered_views={}>> does not implement: current_user

当然,建议将verify_partial_doubles设置为true,但这样做会中断.我直接从文档中提取了这个：

https://www.relishapp.com/rspec/rspec-rails/v/3-1/docs/view-specs/view-spec#passing-view-spec-that-stubs-a-helper-method

如果该方法出现在ApplicationHelper中,它将起作用.但是如果它在ApplicationController中并被定义为helper_method则没有这样的运气：

helper_method :current_user,...

def current_user
  return @current_user if defined?(@current_user)
  @current_user = current_user_session && current_user_session.record
end

我想要verify_partial_doubles提供的保护,我该如何解决这个问题？
