Question

我正在学习rspec，我尝试对自己模型的长度进行评估，但我有这些错误并且我不知道出了什么问题？

 #factories/user
 FactoryGirl.define do
  factory :user do
   first_name {"Name"}
   last_name {"Surename"}
   phone_number {"1245767"}
   email {"email@email.net"}
   password {"password"}
  end
 end

user_spec：it { should validate_length_of(:phone_number).is_at_least(7)}

用户模型：validates_length_of :phone_number, minimum: 7

错误：

 User validations should ensure phone_number has a length of at least 7
 Failure/Error: it { should validate_length_of(:phone_number).is_at_least(7)}
   Did not expect errors to include "is too short (minimum is 7 characters)" when phone_number is set to "xxxxxxx",
   got errors:
   * "can't be blank" (attribute: email, value: "")
   * "can't be blank" (attribute: password, value: nil)
   * "is too short (minimum is 7 characters)" (attribute: phone_number, value: 0)
   * "can't be blank" (attribute: first_name, value: nil)
   * "can't be blank" (attribute: last_name, value: nil)

谢谢

@edit

 require 'rails_helper'

describe User do 
 describe 'validations' do
    it { should validate_presence_of :first_name }
    it { should validate_presence_of :last_name }
    it { should validate_presence_of :phone_number }
    it { should validate_length_of(:phone_number).is_at_least(7)}
 end
end

当使用隐式主题时，RSpec会为您实例化该类，例如：

describe User
  it { should_blah_blah }
end

此时主题（意为it引用的内容）是通过调用User创建的User.new实例。这对于某些单元测试很方便，但在您的情况下，您希望使用工厂初始化用户。使用明确的主题，例如：

describe User
  subject { build(:user) }
  it { should_blah_blah }
end

现在主题是从工厂定义初始化的User实例。
