Question 1

How to set up Stryker.NET in a .NET Core project?

Accepted Answer

Install it globally using 'dotnet tool install -g dotnet-stryker', navigate to your unit test project folder, and run 'dotnet stryker'. Refer to the getting started guide for detailed steps and configuration options.

Question 2

Stryker.NET vs code coverage tools like Coverlet – which is better?

Accepted Answer

Stryker.NET measures test effectiveness by simulating bugs, while code coverage only shows which code is executed. Use Stryker for rigorous quality assurance, but combine with coverage for a holistic view, as each serves different purposes.

Question 3

Does Stryker.NET work with xUnit or NUnit test frameworks?

Accepted Answer

Yes, Stryker.NET is compatible with common .NET test frameworks like xUnit, NUnit, and MSTest. It runs your existing test suite to detect mutations, so ensure your tests are properly configured in the project.

Question 4

How can I speed up Stryker.NET runs for large codebases?

Accepted Answer

Use configuration options to limit mutation types, exclude certain files, or run in parallel. However, mutation testing is inherently slow, so consider running it only in CI/CD or for critical code sections.

Question 5

What does a high mutation score mean in Stryker.NET reports?

Accepted Answer

A high mutation score indicates that most simulated bugs were detected by your tests, suggesting a robust test suite. A low score highlights gaps where tests might miss real defects, guiding improvements.

Question 6

Can I integrate Stryker.NET with Azure DevOps or GitHub Actions?

Accepted Answer

Yes, Stryker.NET can be integrated into CI/CD pipelines using command-line execution. Generate reports like HTML or JSON for visualization, and use badges to display mutation scores in dashboards.
