Nix に興味があるけど、何から始めたらいいかわからない人のための入門書です。 Homebrew など従来のパッケージ管理の状態から少しずつ Nix 管理に置き換えていく方法を解説します。 Nix を活用するのに必要な知識を体系的にまとめるのを目的としています。 本書は下記レポ

The student asked: “Master, what should I pay more attention to, my tests or my code?”. The master said: “I cannot answer you when you ask the wrong question.” The student thought “oh fuck, here we go again”, but just said: “But master, is it not one or the other?” The master said, “If a bridge is suspended from the pillars. Which is more important the walkway or the pillars?” The student thought for a while and asked: “What about the suspensions?” The master nodded. And the student was enlightened.

この1年で、生成AIが自然言語を解釈してブラウザを操作する、Browser UseやPlaywright MCPといった自動テストの仕組みが次々と登場しました。しかし、これらのツールは一体どのようにWebサイトを『見て』、私たちの指示を解釈しているのでしょうか？ 本セッションでは、そのAIの『視点』の正体の1つであるアクセシビリティツリーに焦点を当てます。Playwright MCPのソースコードをベースに、自然言語の指示がどのように解釈され、どのUI要素が特定されるのか、その内部プロセスを見ていきます。また、実際にRailsのシステムテストで使用するCapybaraドライバを作って、Railsとのつなぎの部分についても解説していきます。
