Executing the very short development cycle of test-driven development requires discipline and practice. However, the .NET ecosystem offers a wide variety of tools that support us in authoring a high-quality suite of unit tests, not only defending production code against defects but also enabling safe refactoring of codebases.
Utilizing the magnificent Stryker.NET, we explore how mutation testing can further improve the effectiveness of C# test suites by testing our unit tests with this technique, and how to continuously integrate it into Pipelines and Workflows. Moreover, we will take a peek under the hood of mutation testing and its possible implementations.
Let's kill some mutants!
