Rails Tutorial 11章「11.3.3 有効化のテストとリファクタリング」のテストでエラーが発生してしまう

Question

前提・実現したいこと

Rails Tutorial 11章「11.3.3 有効化のテストとリファクタリング」テストでのエラーを解消したいです。
user_signup_test.rbのassert user.reload.activated?が原因のようです。

試したこと

スペルミスかと思いtutorialをコピペしてみましたが、結果は同じでした。
すみませんがアドバイスをお願いします。

Answer 1

user.rbの記載ミスでした。お騒がせしました。

修正前

  def authenticated?(attribute, token)
    digest = self.send("#{attribute}_digest")
    return false if digest.nil?
    BCrypt::Password.new(digest).is_password?(token)
  end

修正後

  def authenticated?(attribute, token)
    digest = send("#{attribute}_digest")
    return false if digest.nil?
    BCrypt::Password.new(digest).is_password?(token)
  end
