问题描述

也许是一个愚蠢的问题,但是当我尝试在 Ruby 上运行测试时遇到问题,这是错误:

错误:UsersLoginTest#test_login_with_valid_information:

NoMethodError:#UsersLoginTest:0x0000555ef3ec15b0 的未定义方法“用户”您的意思是?超级测试/集成/users_login_test.rb:6:in `setup'

我试图修复夹具 .yml 但我不确定问题是否存在。

这是我的 users.yml

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>

这是我的 users_login_test.rb

require 'test_helper'

class UsersLoginTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
  end
  
  test "login with valid information" do
    get login_path
    post login_path, params: { session: { email:    @user.email,
                                          password: 'password' } }
    assert_redirected_to @user
    follow_redirect!
    assert_template 'users/show'
    assert_select "a[href=?]", login_path, count: 0
    assert_select "a[href=?]", logout_path
    assert_select "a[href=?]", user_path(@user)
  end
end

这是我的 test_helper.rb

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class UserTest < ActiveSupport::TestCase
  fixtures :all
  include ApplicationHelper

  setup do
    @user = User.new(name: "Example User", email: "user@example.com",
                     password: "foobar", password_confirmation: "foobar")
  end
  test "should be valid" do
    assert @user.valid?
  end
  
end

问题出在哪里?非常感谢您的帮助

irb(main):002:0> User.column_names

=> ["id", "name", "email", "created_at", "updated_at", "password_digest"]

我尝试更改 password_digest: 123456,但它引发了同样的错误。我尝试更改密码:test_password,结果如下:

用户测试#test_should_be_valid:

ActiveRecord::Fixture::FixtureError: 表“用户”没有名为“密码”的列。

我还附上了我的 gem 文件,我认为唯一用于身份验证的文件是 gem 'bcrypt':

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

以防万一我创建了一个存储库:https ://github.com/cochabambinoski/Share-Exercise

解决方案


好的,您的问题是您将其设置test_helper.rb为测试本身,这会导致您出现问题。您的文件应如下所示:

#test_helper.rb
ENV['RAILS_ENV'] = 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase #you were creating a new class in your code
  fixtures :all
  include ApplicationHelper

end

就是这样,克隆您的存储库后,我所要做的就是捆绑安装,然后执行rake db:createand rake db:test:prepare. 现在测试通过了。不要忘记将您的灯具改回:

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>

这里的重要教训是test_helper.rb一些配置和设置的地方,而不是放置测试的地方。
