      1ヶ月ほど前に、Firestoreのルールの単体テストに使う @firebase/rules-unit-testing がメジャーバージョンアップデートされました(v1 → v2)。個人的にこのバージョンアップによる改善は、わかりやすくかつ使いやすくなっていて好感を持てたので紹介します。 ちなみに、Firebase JS SDKを v8 → v9 にアップした際に気づきました。 変更点 公式ドキュメントでもしっかり説明されているのでこちらもご参照ください。 TypeScriptで紹介していきます。実際に動いているものが見たい方は以下のリポジトリを見るのが手っ取り早いかと思います。 @firebase/rules-unit-testing は 2.0.1 で動かしています。 v1(以前までのバージョン) import { v4 as randomString } from 'uuid' im

And of the above categories, while useful for root cause analysis and eventual fix, for sake of triaging results, and disposition of what to do if hitting such a failure, it seems that whether or not the failure is a true product failure is a HUGE difference from the other three. For the other three, the major r

Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas
