Ruby on rails 当我将此自定义验证添加到我的用户模型时，空rspec失败

我有一个用户模型，如果我添加此自定义验证，我的空rspec测试将失败：

validate :password_complexity 

def password_complexity
    if !password.blank?
        errors.add(:password, "must contain a upper case character") if password.match(/[A-Z]/)
    end
end

Rspec：

require 'rails_helper'

RSpec.describe User, type: :model do

end

我运行

rspec spec/models/user_spec.rb

得到：

为什么会这样？如果我删除该自定义验证，它运行良好

我的模型是：

class User < ActiveRecord::Base
    has_secure_password 

  belongs_to :account

    validates :email, uniqueness: { scope: :account_id }
    validates_presence_of :email
    validates_presence_of :password, :password_confirmation, on: :create

    validates_length_of :password, :minimum => 8, :maximum => 32, :allow_blank => false
    #validate :password_complexity 


    def password_complexity
        if !password.blank?
            errors.add(:password, "must contain a upper case character") unless password.match(/[A-Z]/)
        end
    end
end

class用户errors.add(:password, "must contain a upper case character") if password.match(/[A-Z]/)

errors.add(:password, "must contain a upper case character") unless password.match(/[A-Z]/)
