hi do you have a (.Net) SDK installed on this machine ? Stryker needs a complete build environment to run. For some reason, dotnet build solution.sln failed so Stryker tried to use MsBuild instead. But it failed to find any instance of it, so it simply failed. I am not use Stryker invokes MsBuild properly on Linux; this logic was intended for old Desktop framework/net classic (or whatever it is called these days). The main question is why dotnet build failed. Sadly, Stryker does not currently provide details for this step

mu88 commented 1 month ago

Thx for your reply.

Yes, the .NET SDK is installed on this machine. If that wouldn't be the case, it should already fail on the very first run (i. e. project-a), shouldn't it?

dupdob commented 1 month ago

I am not sure single project would fail: they could pass if they are light enough. I just updated my PR to improve on logging for such a situation and use 'dotnet msbuild' on Linux (instead of MsBuild.Exe). It will at least provide details on why dotnet build fails. Could try running dotnet build on the solution and see what happens?

mu88 commented 1 month ago

That was a good guess, man 💪🏻 running dotnet build ProjectD.sln fails with the following error:

/usr/share/dotnet/sdk/8.0.300/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error NETSDK1100: To build a project targeting Windows on this operating system, set the EnableWindowsTargeting property to true. [/home/jenkins/agent/workspace/s_Utility_MutationTesting_master/project-d/src/ProjectD.TestApp/Company.ProjectD.TestApp.csproj]

When changing this to dotnet build ProjectD.sln -p:EnableWindowsTargeting=true, the build succeeds. So the question is: can I somehow pass the MSBuild argument EnableWindowsTargeting to Stryker or do I have to set it in the corresponding Company.ProjectD.TestApp.csproj?

dupdob commented 1 month ago

Thanks, but that's not a guess, it was logged.

09:07:41  [07:07:41 INF] Building solution Company.ProjectD.sln
09:07:43  [07:07:42 WRN] Dotnet build failed, trying with MsBuild.

As of today, there is no way to pass MsBuild properties across Stryker, but you can add the properties in windows targeting projects' csproj files:

<PropertyGroup>
  <EnableWindowsTargeting>true</EnableWindowsTargeting>
</PropertyGroup>

I think it should do the trick

You can probably set this with a condition Condition=" '$(OS)' != 'Windows_NT' " so it's only set on non-windows operating systems. See: https://stackoverflow.com/questions/43499222/how-to-get-the-current-operating-system-in-msbuild

Thx, I will give it a try and report back

I tried it yesterday multiple times with enabling EnableWindowsTargeting and confirmed that this works. So first of all thank you for your help 💪🏻

However, what I don't understand is the following: I'm using a Stryker config file like this:

{
  "stryker-config": {
    "test-case-filter": "Category=Unit",
    "project": "Company.ProjectD.Features",
    "test-projects": ["tests/Company.ProjectD.Tests.Component/Company.ProjectD.Tests.Component.csproj"]
  }
}

According to the docs, I'm not using Stryker's solution file context, but yet the solution is built by Stryker. When only running dotnet build tests/Company.ProjectD.Tests.Component/Company.ProjectD.Tests.Component.csproj, the necessary projects are built successfully on the Linux host without adding EnableWindowsTargeting. This somehow contradicts what the docs are implying 🤔

When you run from a folder containing a solution file, you run in solution mode. Since you're specifying a relative path to your test project and are setting a project name, it does indeed look like you're running in solution mode. The pipeline also makes it seem like you're running in solution mode since you seem to set the working directory to the repository root: dir("${repositoryName}").

So I have to explicitly dir out of the Solution directory to force Stryker into the solution mode, got it. Thx for the clarification 👍🏻

The primary way stryker determines the execution mode is based on the information available (do we have a solution file, do we have a project file, do we have a test project file). This information can be provided using config but stryker also tries to auto-detect this based on the current working directory. If the current working directory contains a solution file, we automatically run in solution mode. If the current working directory contains a project file we try to determine whether or not this is a test project. If it is a test project, we run in test project mode. Otherwise we run in source project mode. If no solution file or project file is found in the working directory we base the mode to use solely on the configuration provided by the user.
