RubyでdummyデータをRandomで値を生成して作成する

論文みたく書くのは苦手なので記述だけ。

def self.__create_dummy_tests
    50.times do
      Test.create({
        company_id: rand(Company.count),
        user_id: rand(User.count),
        send_at: Random.rand(Time.zone.now.ago(2.month)..Time.zone.now),
        form_id: SecureRandom.base64(20),
        answered_at: [nil, Random.rand(Time.zone.now.ago(2.month)..Time.zone.now)].sample,
        is_active: [true, false].sample
      })
    end
  end
