Streamlitでテスト工数を削減した話 2024/09/17 老木 智章

© go inc. 2 概要 タクシーアプリ『go』のタクシー手配の仕様は複雑さが増す一方。 品質管理チームはテストが失敗しても原因がわからず、 開発エンジニアへ調査依頼を出すしかないケースが増加していた。 さらに、配車はマイクロサービスによって実現されており、 どのサービスが失敗原因かの調査は開発エンジニアでも大変だった。, © go inc. 3 著者背景 name : 老木 智章 role, © go inc. 4 ログ分析によるテスト失敗原因調査 テストに失敗した際は、各サービスのログを調査する。 ログはbigquery上のさまざまなテーブルに出力されており、適切な 調査クエリを発行するのは、多くのエンジニアには面倒。 さらに、ログを読み解くには各サービスに詳しい必要があり、調査に は複数のエンジニアが必要になるシーンが多かった。, © go inc. 5 配車失敗ログの読解に専門知識が必要な例 各車両は「配車能力」というビットフィールドで、対応しているサー ビスを管理している。 一方、リクエストは「要求配車能力」 を持っている。 ログには、「要求配車能力を未達」というメッセージと各ビット, © go inc. 6 01 streamlit による解決, © go inc. 7 streamlit とは？ pythonで極めて簡単にウェブアプリを作れる。 st.title(“web page”) st.dataframe(pd.read_gbq(“select, © go inc. 8 streamlit によるログ閲覧ツール作成 サービスの各ログごとにログ閲覧ツールを作成した。 内部的なエラーコードの解説をつけている。 → 専門知識がなくとも対処可能に！, © go inc. 9 streamlit を使うメリット 以前はログ閲覧ツールをreactやlookerで作成していたが、 streamlit は ▪, © go inc. 10 表現力の高さの例 ui操作結果をグラフにリアルタイムに反映させやすい。, © go inc. 11 ツール細分化のメリット 複数のログを横断的に見るツールを作らず、 ログごとの小さいツールをリンクで繋げている。 これによって、 ▪ ログ読み込み時間の短縮, © go inc. 12 02 普及活動, © go inc. 13 ツールを使ってもらうために 品管チームや各サービスの開発チームを対象に、使い方やどういった 仕組みで配車が成り立っているかのプレゼンを実施。 さらに各ツールで、閲覧したログを共有できる機能を追加。 リンクをコピーするとフォームの入力内容が共有できる。 リンクをしつこく問い合わせ返答の際に貼ることでツールに誘導。, © go inc. 14 ツールを作ってもらうために streamlit によるユーザー主導の調査を広めるためには、 より多くのツールが作られて欲しい。 共有リンク生成関数のような便利関数を広めている。 関数一つで共有リンクが生成できる。, © go inc. 15 結果 調査が品質管理チームでも実施可能になり、問い合わせは激減。 製作コストは十分ペイした 　→　みんな自分でわかるなら問い合わせはしたくない 　→　品管チームの動作チェック手順にも採用されるように！ 問い合わせの際も、ツールのリンクとともに問い合わせが来るように, © go inc. 文章・画像等の内容の無断転載及び複製等の行為はご遠慮ください.

Get ready to see more PlayStation games. Sony is hosting a State of Play presentation tomorrow, September 24th, and the company says it will feature news and updates on “more than 20 upcoming PS5 and PS VR2 games from studios around the world.” Sony says the State of Play will be more than 30 minutes long, and you’ll be able to watch it at 6PM ET / 3PM PT on YouTube and Twitch.

The show is taking place just two days before preorders for the PS5 Pro are available. Sony’s initial presentation about the PS5 Pro was a little lacking , so hopefully we’ll get some better looks at games that will be enhanced by the new console.

In a May State of Play , Sony shared information about Astro Bot , one of the best games of the year , and Concord , which was a disastrous flop that Sony took offline shortly after it launched.
