Run Stryket on a solution with multiple test projects

[CarlosEGSouza]

Hello,

In my solution i have three test projects (Unit, UI and Integration). How do i run stryker only in a unit test project? (C# net6.0 in VS 2002)

I created a stryker-config.json in the solution path like this, but aways stryker runs ALL tests from all three projects. Why??

{
    "stryker-config":
    {
        "mutation-level": "Complete",
        "test-projects": ["Project.Test.Unit/Project.Test.Unit.csproj"]
    }
}

Looks like it's tied to so called "solution context" - when you run it from the solution directory, it analyzes the whole solution.
I've managed to filter tests by using "test-case-filter": "Category=Unit", requiring the attribute depending on the testing framework: https://github.com/Microsoft/vstest-docs/blob/main/docs/filter.md

Sorry I forgot to reply to this question. This is the correct way to do this yes!

Instead of filtering you can simply execute the dotnet stryker command from the unit tests project folder. That way it will build and execute only the unit test project instead of building the entire solution and execute all tests.
