Hello,

Mutation testing is a technique that helps you understand the quality of your tests. It introduces bugs in your production code and then runs your tests and makes sure they fail - proving that they are indeed providing the safety net you need.

In Java there has been a tool for a long time called http://pitest.org/

However in .NET we still don't have an actively maintained / working tool that does this.

This why I'd like us all to vote this user voice idea that asks Microsoft to build this in Visual Studio themselves. So please have a look and upvote this if you find it useful as well: https://visualstudio.uservoice.com/forums/121579-visual-studio-ide/suggestions/20500363-support-mutation-testing-for-c

Thank you.
