Question

我一直试图弄清楚如何测试，但似乎没有什么能解决我的问题。每次我尝试运行任何测试时，都会收到此错误：

NoMethodError: undefined method `users' for #<#<Class:0x00560775e00768>:0x00560775e00470>

我如何在模型中运行我的测试：ruby test/models/plan_test.rb

我正在尝试运行最基本的测试（Rails给我一个例子），所以它没有链接到任何模型/夹具。我的模特：

require File.expand_path("../../test_helper", __FILE__)

class PlanTest < ActiveSupport::TestCase
  test "the truth" do
    assert true
  end
end

我也创建了一个空的测试数据库，当我尝试在数据库中添加fixture时，我得到了同样的错误。

感谢您寻找：）

编辑：跟踪夹具命令（rake db:fixtures:load RAILS_ENV=test --trace）：

[DEPRECATION] `last_comment` is deprecated.  Please use `last_description` instead.

      subscription_id: 1
      subscription_next_bill_date:
      email_hash: 1
      referred_by_user: two (or the way you named the self reference)
      subscription_status: deleted

检查您是否拥有名为app/models/user.rb的有效模型文件，如果您使用rails g model user生成了用户模型，或者您已为用户表创建了迁移，则表明您运行了迁移。< / p>

RAILS_ENV=test rake db:migrate

您的app/models/user.rb至少应包含：

 class User < ActiveRecord::Base
 end

更新：您在下面的评论表明您已删除了迁移文件。您可以随时让测试数据库通过执行来镜像开发DB rake db：test：prepare
