ruby-on-rails - 使用 MiniTest 测试用户模型(设计身份验证)

Question

我正在尝试测试用户模型，为此我设计了身份验证。

我面临的问题是，1. fixture 中有“password”/“password_confirmation”字段会给我无效列“password”/“password_confirmation”错误。

1. 如果我从 fixture 中删除这些列并添加到 user_test.rb

   require 'test_helper'
   
   class UserTest < ActiveSupport::TestCase
   
   
         def setup
           @user = User.new(name: "example user",
                            email: "example@example.com",
                            password: "Test123",
                            work_number: '1234567890',
                            cell_number: '1234567890')
         end
   
         test "should be valid" do
           assert @user.valid?
         end
   
         test "name should be present" do
           @user.name = "Example Name "
           assert @user.valid?
         end
   
       end
   

我得到的错误是:

  test_0001_should be valid                                       FAIL (0.74s)
Minitest::Assertion:         Failed assertion, no message given.
        test/models/user_test.rb:49:in `block in <class:UserTest>'

  test_0002_name should be present                                FAIL (0.01s)
Minitest::Assertion:         Failed assertion, no message given.
        test/models/user_test.rb:54:in `block in <class:UserTest>'


Fabulous run in 0.75901s
2 tests, 2 assertions, 2 failures, 0 errors, 0 skips

我想知道为什么我的用户对象无效？

谢谢

经过如下调查后，我得到了解决方法:为夹具添加辅助方法:

# test/helpers/fixture_file_helpers.rb
module FixtureFileHelpers
  def encrypted_password(password = 'password123')
    User.new.send(:password_digest, password)
  end
end

# test/test_helper.rb
require './helpers/fixture_file_helpers.rb'
ActiveRecord::FixtureSet.context_class.send :include, FixtureFileHelpers

然后像这样制作夹具:

default:
  email: 'default@example.com'
  name: "User name"
  encrypted_password: <%= encrypted_password %>
  work_number: '(911) 235-9871'
  cell_number: '(911) 235-9871'

并在用户测试中将此夹具用作用户对象。

def setup
    @user = users(:default)
end
