Can't produce coverage in Docker container

[RPM1984]

Hi there,

I'm having trouble getting coverlet to run in my docker container. My problems seems similar to this issue, although the problem persists, and there are some differences.

Setup

• .NET 6 tests project.
• References have Microsoft.NET.Test.Sdk v17.2.0 (latest), and coverlet.collector v3.1.2 (latest)

I'm running the tests in a Dockerfile, like so:

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
COPY ["src/MyAPI/", "src/MyAPI/"]
COPY ["tests/MyAPI.Handlers.Tests/", "tests/MyAPI.Handlers.Tests/"]
WORKDIR "/tests/MyAPI.Handlers.Tests"
RUN dotnet restore "MyAPI.Handlers.Tests.csproj" --configfile NuGet.config

FROM build AS publish
WORKDIR /tests/MyAPI.Handlers.Tests
RUN dotnet publish "MyAPI.Handlers.Tests.csproj" -c Release -o /tests/publish --no-restore

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS final
WORKDIR /tests
COPY --from=publish /tests/publish .
ENTRYPOINT ["dotnet", "test", "MyAPI.Handlers.Tests.dll", "--collect:\"XPlat Code Coverage\""]

So i am doing a dotnet publish, and running the tests from there. That should mean that everything is there, that needs to run the tests / coverage.

When i run, i get this error:

Data collection : Unable to find a datacollector with friendly name '"XPlat Code Coverage"'.

What i've confirmed:

• Command works outside docker fine (e.g if i do a dotnet publish, then dotnet test with coverage)
• I've listed the files in the directory in the container, and confirmed the coverlet DLL's are there

Any suggestions would be great! Thanks in advance :)

Solved. Didn't need the quotes around XPlat Code Coverage.

Fixed line:

ENTRYPOINT ["dotnet", "test", "MyAPI.Handlers.Tests.dll", "--collect:XPlat Code Coverage"]
