Of course you do! But are those tests sufficient? Coverage tools provide an answer. Unfortunately, coverage analysis is often insufficient. Even test suites with 100% code coverage often miss bugs. Some test suites bring only little added value in practice. With Mutation Testing you can check the quality of your tests yourself! Stryker puts your tests to the test. You get a more realistic statement, how well your suite can actually find errors and learn how to improve it. The tool integrates into your project and pipeline with little effort and gets results fast! Learning Objectives: * Understand why 100% coverage means little * Integrate Stryker into your own projects * Improve test suites with the help of mutation reports ## Speaker ### [Marco Emrich](https://www.wearedevelopers.com/@marco-emrich) Consultant and software crafter at @codecentric ## Related talks at this congress - [Test Intelligence for Developers](https://www.wearedevelopers.com/events/world-congress-2024/sessions/418-test-intelligence) — Elmar Jürgens - [Why I Love End-2-End Tests and How To Get Them Right](https://www.wearedevelopers.com/events/world-congress-2024/sessions/27-why-i-love-end-2-end) — Johannes Stern - [Test-reduction - Doing more with less](https://www.wearedevelopers.com/events/world-congress-2024/sessions/272-test-reduction-doing) — Ewald - [Real World TDD](https://www.wearedevelopers.com/events/world-congress-2024/sessions/9-real-world-tdd) — Andreas Kleinbichler
