RSpecにおけるparameterized testingとマネーフォワードにおけるその改善 - Money Forward Developers Blog
こんにちは。 Railsエンジニアのkamillleです。 マネーフォワードのアプリケーションはユーザーの権限やプラン・リクエスト時間等によって異なる振る舞いをするものが多く、そういった機能のテストではparameterized testingを利用することが多いです。マネーフォワードのRailsアプリケーションではテスティングフレームワークとしてRSpecが採用されることが多く、RSpecにおいてどのようにparameterized testingを行っているか紹介したいと思います。 RSpecにおけるparameterized testing RSpecはparameterized testingをサポートしていないので何かしらの拡張を行う必要があります。この拡張としてrspec-parameterizedというgemがあり、このgemが選ばれているケースが多いように思います。rspe
Getting Started With Property-Based Testing in Python With Hypothesis and Pytest - Semaphore
Rodrigo has always been fascinated by problem solving and that is why he picked up programming – so that he could solve more problems. He also loves sharing knowledge, and that is why he spends so much time writing articles in his blog mathspp.com/blog, writing on Twitter @mathsppblog, giving workshops and courses, and talking at conferences. His main areas of scientific interest are mathematics (
Choosing a Sequential Testing Framework — Comparisons and Discussions
Choosing a Sequential Testing Framework — Comparisons and Discussions March 21, 2023 Published by Mårten Schultzberg (Staff Data Scientist) and Sebastian Ankargren (Sr. Data Scientist) TL;DR Sequential tests are the bread and butter for any company conducting online experiments. The literature on sequential testing has developed quickly over the last 10 years, and it’s not always easy to determine

2023年にVisual Regression Testingを始めるならどんな選択肢があるか | ログラス Productチーム アドベントカレンダー 2022
本記事は「株式会社ログラス Product チーム Advent Calendar 2022」12 日目の記事です。はじめにフロントエンドのテスト手法の 1 つに Visual Regression Testing（以下、VRT）があります。 これは、アプリケーションの画面を画像として保存し、画像の差分比較をすることで意図せぬ変更が生じていないかテストする方法です。 ここ数年で広く普及し、用語としても一般的になったように思います。 私も以前、とある OSS に reg-suit & Storycap を使った VRT を導入したことがあるのですが、その後もいくつか VRT のためのライブラリが登場したもののキャッチアップできていませんでした。 そこで今回は知識のアップデートを目的として、ここ最近登場した（と思われる）VRT のライブラリをいくつかご紹介します。 なお、今回紹介するツールはす

React テストコード（Jest, React Testing Library）の学びと Tips - Qiita
はじめに 早いもので2023年も終わりが近づいてきました。皆様はいかがお過ごしでしょうか。毎年アドベントカレンダーの時期になると、今年一年で学び経験した技術の知識を棚卸しするために記事を書いています。2023年はよくテストを書いた年でした。React のテストコードで学んだことを書き記します。 テストにはいわゆる手動テストと自動テストがあります。どちらも必要ですし、用いる手法はケースバイケースなのかなと思います。テストにかける時間や労力は短期的に見るか長期的に見るかで手動テストと自動テストのどちらが良いかは一概には言えません。多くの場合は組み合わせて行うと思います。 テストレイヤーの切り方として、Ice-Cream Cones, Testing Pyramids, Testing Trophy など様々な考え方があります。上層ほど高コスト・低速。下層ほど低コスト・高速と言われています。 出
How Slack models and tests with incredibly large groups of users Complex systems are difficult to reason about at scale; we often can’t accurately extrapolate system behavior and performance, so we need to derive that data empirically. We use load testing to do just that: find the limits of our systems and weed out bugs at a large scale in a controlled environment. Slack is a pretty complex system
Test Flakiness - One of the main challenges of automated testing (Part II)
There are two main reasons for flaky automated tests. 1) Poor Locator Strategy. Find a methodology that is testable before you have to depend upon it in your automated testing. I just posted a video on this topic a week ago, which shares why our team exclusively utilizes xPath for some of the most reliable locators you can build.

GitHub - facebookincubator/CG-SQL: CG/SQL is a compiler that converts a SQL Stored Procedure like language into C for SQLite. SQLite has no stored procedures of its own. CG/CQL can also generate other useful artifacts for testing and schema maintenance.
CG/SQL is a code generation system for the popular SQLite library that allows developers to write stored procedures in a variant of Transact-SQL (T-SQL) and compile them into C code that uses SQLite’s C API to do the coded operations. CG/SQL enables engineers to create highly complex stored procedures with very large queries, without the manual code checking that existing methods require. The full

The five types of Test Doubles are: Dummy: It is used as a placeholder when an argument needs to
