【Techブログ更新】 GoConf mini Sendai 2026に参加した弊社エンジニアがセッションきっかけで、Mutation Testingを導入 AIが生成する"中身のないテスト"をgremlinsで可視化・撃破した記録をまとめました💡 👇 np-techblog.hatenablog.com/entry/mutation… #Go言語 #MutationTesting #テスト品質

Wanna take your tests to the next level? 🚀 #MutationTesting helps you find the weak spots in your code. We'll show you how to implement this technique efficiently and kill those sneaky mutants 👇

¿Quieres llevar tus tests al siguiente nivel? 🚀 El #MutationTesting te ayuda a encontrar las debilidades de tu código. Te contamos cómo implementar esta técnica de forma eficiente y matar a esos mutantes escurridizos. 📝

If your tests don't fail when they should, you have a problem. 🕵️ We explain what #MutationTesting is and how to use it to find weak spots in your testing strategy and ensure your code quality. Read the full post here! 👇🧐

100% code coverage… and your tests still miss bugs? Julius Mischok shows why coverage measures execution, not verification — and how #MutationTesting with #PIT proves whether tests actually fail when code changes. Add PIT + kill surviving mutants: javapro.io/2026/01/21/tes… #Java

¿Crees que tus tests son a prueba de balas? ✋ El #MutationTesting los pone a examen introduciendo errores para ver si saltan las alarmas. Te contamos cómo funciona esta técnica con un ejemplo práctico 👇

Deine Tests laufen bei jedem Build? Dann sind sie wichtig genug, getestet zu werden. Julius Mischok zeigt, wie #MutationTesting mit #PIT Schwachstellen in deiner #CI sichtbar macht. Stärke deine Teststrategie: javapro.io/de/teste-deine… #Java #CleanCode #DevOps #DevTools #JAVAPRO

El #MutationTesting no tiene porqué ser lento 🐌. Con Pitest y una buena configuración, puedes potenciar tus tests en proyectos #Java con #SpringBoot3. Te explicamos cómo excluir clases y optimizar el proceso 🧐👇
