何故か引数の数が合わない

Question

railsチュートリアルの12.2.2をやっていたら、こんなエラーが出ました。

Error:
UserMailerTest#test_password_reset:
ArgumentError: wrong number of arguments (given 1, expected 0)
    app/mailers/user_mailer.rb:8:in `password_reset'
    test/mailers/user_mailer_test.rb:21:in `block in <class:UserMailerTest>'

コードがこちらです。
どこが間違っているのかわかった方、教えていただけると幸いです。もう二、三日試行錯誤しても治らず悩んでいて全く進みません

User_maller.rb:

class UserMailer < ApplicationMailer

  def account_activation(user)
    @user = user
    mail to: user.email, subject: "Account activation"
  end

  def password_reset
    @user = user
    mail to: user.email, subject: "Password reset"
  end
end

user_maller_test.rb:

require 'test_helper'

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    user = users(:michael)
    user.activation_token = User.new_token
    mail = UserMailer.account_activation(user)
    assert_equal "Account activation", mail.subject
    assert_equal [user.email], mail.to
    assert_equal ["[e-mail]"], mail.from
    assert_match user.name,               mail.body.encoded
    assert_match user.activation_token,   mail.body.encoded
    assert_match CGI.escape(user.email),  mail.body.encoded
  end

  test "password_reset" do
    user = users(:michael)
    user.reset_token = User.new_token
    mail = UserMailer.password_reset(user)
    assert_equal "Password reset", mail.subject
    assert_equal [user.email], mail.to
    assert_equal ["[e-mail]"], mail.from
    assert_match user.reset_token,        mail.body.encoded
    assert_match CGI.escape(user.email),  mail.body.encoded
  end
end

Answer 1

def password_reset

仮引数がない

おそらく

def password_reset(user)
  @user = user
  mail to: user.email, subject: "Password reset"
end

が正しいかと

回答ありがとうございます。
それに変えてみましたが、わけわからんエラーコード大量に出ました。
どうやら違ったみたいです。
一応そのエラーも載せます。

railsチュートリアルのバグに近い挙動ですね
余計なカスタマイズをやめてpassword_reset.text.erbを原文通り英語のみにしてください

治りました！ありがとうございます！！！！！
文字コードに原因があったんですね勉強になります
