セッション概要

Everything from Scratch: A journey as Software Engineer in Test to improve "Testing"

伊藤 宏幸 (LINE株式会社 DSEセンター SET／@hageyahhoo)

テスト自動化やDevOpsなどの改善活動を進める際、抵抗や反対などの様々な問題に遭遇することが常です。
一方でこれらは、「適切な」アプローチで克服することが可能です。
LINEのSET（Software Engineer in Test）として、実際に問題に遭遇し解決し続けた経験を通じて、文字通りイチから作り上げた下記の実践的なアイデアやソリューションについてお話します。

1) 同僚・意思決定者から理解・支援を得る方法
2) 開発チームと「一緒に痛い目にあう」重要性
3) 創発的なメンバー・チーム・組織を作る仕組みづくり

皆さんがこれらの問題を克服するためのヒントになれば幸いです。

※Agile2020で予定していた発表を、日本語で行います。

Reduce flaky test cases with Gradle retry plugin and Allure report

Elena Alejo（エレナ アレホ） (LINE株式会社 DSEセンター SET)

At LINE we love testing, for that reason at LINE-Shop team, we have more than 11.000 test cases.
Having this amount of test cases, increase the probabilities of having flaky test cases. So as result, during our continues integration cycle our builds can end up broken due a false failed test cases!
During this talk, I will share how we resolve this issue using Gradle Retry Plugin & Allure report tools.

Session Information

Everything from Scratch: A journey as Software Engineer in Test to improve "Testing"

Hiroyuki Ito (LINE Corporation, DSE Center SET, @hageyahhoo)

When introducing improvement activities to your team, like Test Automation, you will face challenges. Some members and/or teams may oppose your activities. You may find that no one uses tools or solutions you introduced. You may face a shortage of members who have enough skills and knowledge.

As an SET (Software Engineer in Test), I faced a lot of challenges and failures. No clear goals. Dissension among developers, testers, and managers. Negative feedback to my/our solutions... However, I could overcome them and finally achieved something great!

We can change difficulties into something special with proper approaches!

In this talk, I will tell you the following practical ideas and solutions which relate to testing I found through my experience as SET from Scratch:

1) Importance and how to get support and understanding from decision-makers and colleagues
They are critical to proceed with test-related improvement activities. I will explain useful techniques; "Product Discovery" to discover their real concerns, and "Giving impacts" to attract them.

2) Experiencing hardships with product development teams together is a key to proceed with activities
We learned that we could provide innovative ideas and solutions by working closely with product development teams. I will explain it through our experience of inventing and improving our failure detection system with "Karate" framework, an open-sourced API Testing framework in which we can write test scripts with BDD (Behavior-Driven Development) style.

3) How to nurture members/teams/organizations for your innovative activities
Innovative activities require proper skills, knowledge, persons, and so on. I will tell you "Learning Session", a way to nurture members, teams, and organizations smoothly and quickly. Additionally, I will explain "Sebas Report", our innovative solution example to tame the complexity of Microservices and reduce their outages incubated from "Learning Session".

I have been sharing these my improvement ideas over 10 times with our company members. After that, some teams convinced themselves with my ideas and started utilizing them. One team solved its slow test problems on their own. Another team invented a new test infrastructure which made testing easier.

I hope these ideas will help innovate your testing activities!
