Exciting new features for Stryker.NET | Stryker Mutator

The new Stryker.NET is packed with a lot of new awesome features 🚀 For the past few months we've been working hard and introduced a lot of new mutators. This can have an effect on your mutation score. So don't be surprised if your score comes out a bit higher or lower after updating. Here is a short summary of everything new.

Congrats on this release 🎉. A huge milestone! "Test all projects in a solution" will be a game changes for larger projects!

Right now I've got next structure of the application:
sln
|--src
|--.API
|--.Application
|--.Core
|--.Contracts
|--.Client
|--.Infrastructure
tests
|--.API.UnitTests
|--.Application.UnitTests
|--.Infrastructure.UnitTests

I want to mutate and test only API, Application and Infrastructure. Mutations work perfectly if I started them from every test project directory. But in this case there are three separate reports with numbers at the end created (e.g. mutation-report-1, mutation-report-2 etc.). So I've got next questions:

1. Is there a way to name every report after Project Name that is mutated if I started mutations from Test Project Context?
2. Is there a way to exclude some projects that I don't need to be mutated from Solution Context?

1. Stryker doesn't generate these names. Looks like you're talking about the azure devops extension? There's an option in Stryker to set the report file name: https://stryker-mutator.io/docs/stryker-net/configuration/#report-file-name-string There's also an option in the extension to use the report file name instead of "1, 2, 3" as the display name. Combine these two to get your desired result.
2. There is currently no way to do this in solution mode.
