はじめに 業務でPlaywrightの環境構築及びCI/CD連携担当したことから、E2EテストとVRTのベストな構成をずっと悩んでいました。 自分の中である程度納得できる形まで落とし込めたので、その知見を残しておきます。 🎭Playwrigth Microsoftが開発したテストツールです。複数ブラウザ対応、自動待機機能、並列処理などによりE2Eテストを実施します。また、スクリーンショットの比較によるテスト（VRT:Visual Regression Testing）により視覚的変更も検出可能です。元々Puppeteerを作っていたチームにより開発が行われているようです。 ツールの比較対象にcypressがありますが、最近の週間ダウンロード数はPlaywrightが上回っているようです。 （他にはSeleniumやベンダー提供の有料E2Eテストツールなどもあります） また、Playwri

Sometimes debuggers and profilers are obviously broken, sometimes it's subtle and hard to spot. From my flame graphs page: (Click for original SVG.) This is pretty common and usually goes unnoticed as the flame graph looks ok at first glance. But there are 15% of samples on the left, above "[unknown]", that are in the wrong place and missing frames. The problem is that this system has a default li
タイトルからREST APIのテスト技法や実装方法が中心の内容かと想像していましたが全12章に渡って、「ちゃんとプロダクトを理解し、計画を立ててから機能・非機能双方でAPIに対するテストを行う」という包括的な内容で良い意味で驚きました。 特にテスト計画に時間をかけすぎずに整理する考えや、 Explore It! という探索的テストの本を参照しながら、何をテストするか整理する方法は具体的なHowに寄りすぎず、非常によかったです。 心に残ったポイントの紹介 ここからは書籍を読んで特に私の心に残ったことを紹介します。 Chapter 2: Beginning our testing journey 本書の第2章では、APIテストを始める前の重要なステップとして「プロダクトを深く理解すること」が強調されています。 The more we learn, the clearer our strateg
This article is a translation, the original version is available here. I started using the OCaml language regularly around 2012, and since then, my interest and enthusiasm for this language have only grown. It has become my preferred choice for almost all my personal projects, and it has also influenced my professional choices. Since 2014, I have been actively participating in public conferences d
Exactly ten years ago today, we published "Why We Created Julia", introducing the Julia project to the world. At this point, we have moved well past the ambitious goals set out in the original blog post. Julia is now used by hundreds of thousands of people. It is taught at hundreds of universities and entire companies are being formed that build their software stacks on Julia. From personalized me

The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. 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

research!rsc: Hash-Based Bisect Debugging in Compilers and Runtimes
Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists
Testing in the Twenties
[This fragment is available in an audio version.] Grown-up software developers know perfectly well that testing is important. But — speaking here from experience — many aren’t doing enough. So I’m here to bang the testing drum, which our profession shouldn’t need to hear but apparently does. This was provoked by two Twitter threads (here and here) from Justin Searls, from which a couple of quotes:
