万葉のRails新人研修のコードレビューコメントを分析してみました

 万葉のRails新人研修のコードレビューコメントを分析してみました

Railsdm2019 でのトーク資料です。

---

(株) 万葉ではここ2年以上、新入社員教育用カリキュラム(https://github.com/everyleaf/el-training)を利用して、新入社員にRailsの研修を受けてもらっています

本トークでは、これまでの実際の研修で出された数々の Pull Request に社員が寄せたたくさんのコメントを、発話の目的やトピックといったいくつかの観点で分類し、傾向を紹介します。そして、初心者がRailsを学ぶ上で重要なポイントや、周囲がサポートするとよい点、レビューのコツなどについて考察します。

We have been carrying out our Rails training program for new employees for over 2 years in Everyleaf Corporation. In those trainings, many pull requests had been reviewed by other employees.

In this talk I'm going to introduce an analysis of code review comments of those pull requests and think about the important points in learning Rails, supporting beginners and code review styles.
