ruby-on-rails - Rspec， rails : how to test private methods of controllers?

Question

我有 Controller :

class AccountController < ApplicationController
  def index
  end

  private
  def current_account
    @current_account ||= current_user.account
  end
end

如何使用 rspec 测试私有(private)方法 current_account？

附注我使用 Rspec2 和 Ruby on Rails 3

Answer 1

使用#instance_eval

@controller = AccountController.new
@controller.instance_eval{ current_account }   # invoke the private method
@controller.instance_eval{ @current_account }.should eql ... # check the value of the instance variable
