How to incorporate Stryker.NET tool in Azure DevOps pipelines in case of multiple project dependencies in a test project?

Question

I have a unit test project file which depends on two other projects. ABC.Service.UnitTest is the test project and its dependencies are XYZ.Service.csproj and LMN.Aggregator.csproj.

In this case, what exactly do we need to have in our config file and how exactly can we incorporate this scenario into our ADO pipelines?

Answer 1

You can specify the project you want to mutation test using -p option:

dotnet stryker -p XYZ.Service.csproj
dotnet stryker -p LMN.Aggregator.csproj

Alternatively, you can use project config file option, though you'll need to have two config files then. Either way, this will produce two different reports in the two latest StrykerOutput folders.

What to do with this - depends on you. For example, you can attach these files to builds using the dedicated extension, see the full guide here.
