Testing Your Code in Golang
Writing tests for a software application before moving it into production is an essential last step in the software delivery system. However, it is expedient that you know how to write highly maintainable unit tests if you are working with production-ready software up close. Tests reduce the possibility of producing software with bugs and vulnerabilities and making users happy. This article will d
How GitHub reduced testing time for iOS apps with new runner features
GitHub Actions GitHub for iOS The GitHub iOS and GitHub Actions macOS runner teams are integral parts of each other’s development inner loop. Each team partners on testing new runner images and hardware long before the features land in the hands of developers. GitHub Actions has been working hard at bringing the latest Mac hardware to the community. Apple silicon (M1) macOS runners are available f
Visual Regression Testing
Image Source: Visual Regression Testing Tools“When we talk about visual regression testing, we are concerned with preventing unintentional changes to our application’s visuals. If we change the styles of a Button component, how can we be sure that we haven’t messed up the styles of our ButtonGroup?” Regression testing, in general, is validating that the changes we introduce to our source code do n
GitHub Actionsを利用したE2E自動化テストの実現 ～ Achieving E2E Automated Testing with GitHub Actions ～ 利用GitHub Actions实现E2E自动化测试 - スタディサプリ Product Team Blog
こんにちは。スタディサプリのQAチームです。 今回のBlogではスタディサプリで実施している自動化テストの一部の取り組みについて紹介させていただきます。 なお、スタディサプリQAチームの特性を活かし、本記事については日英中３言語で記載します。より多くのオーディエンスに読んで頂ければ嬉しいです。 自動化する動機 まず、なぜ自動化テストを導入するのでしょうか。 1. 新規機能が追加される度に、既存機能への影響を確認するための回帰テストをしなければなりません。 2. 繰り返し同じテストを手動実行することにより、テストコストが増加します。 3. 人間が実施すると、人為的ミスによる不具合の検出漏れが発生してしまう可能性が否定できません。 そのため、品質を担保した上でより早くリリースすることを目的とし自動化を導入しました。 現在の開発およびテストフロー QAが回帰テストの自動化テストスクリプトをGit

Unit Testing React without Jest
Unit Testing React without Jest Jest is clearly a polished testing tool, but with the advent of Node.js 18, we really don't need it any more. Jest also has a huge surface area, is perhaps inexorably linked to Webpack, and needs its own binary—you can't just "run the tests" as a script. So it has some modern challenges. This blog post will teach you how to set up your code, rather than provide an a
