Coverlet is generating 0% line coverage

[VenkateshSrini]

Hi,
code coverage with coverlet.mbuild and .NET core 3.1 is giving issue. It is showing 0% code coverage when run using dotnet test command. The code can be been at
https://github.com/VenkateshSrini/FSEPMAPI.

The command that is used to generate code coverage is provided in runCoverage.cmd

I did some test and seem you're hitting know issue with msbuild driver https://github.com/tonerdo/coverlet/blob/master/Documentation/KnownIssues.md#1-vstest-stops-process-execution-earlydotnet-test
We have an old issue that uses RavenDB with same problem #342
I did a test with vstest integration throught collectors and works https://github.com/tonerdo/coverlet/blob/master/Documentation/VSTestIntegration.md

[VenkateshSrini]

Is there some work around that I can adopt to get the report. I need this to be submitted to management

[MarcoRossignoli]

Yes as I said you need to use collectors integration and not use msbuild follow guide https://github.com/tonerdo/coverlet/blob/master/Documentation/VSTestIntegration.md

I cloned your repo, added to test project

    <PackageReference Include="coverlet.collector" Version="1.2.1">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>

Run from root repo

dotnet test --collect:"XPlat Code Coverage"

and with report generator I generated html reports in same way.

Hi,
I tried it. It works well. I have only a small problem. I used the following code dotnet test --collect:"XPlat Code Coverage" -r "_codeCoverage" inside the _codeCoverage another directory whole name is a Guid is getting generated. It is becoming difficult to generate the reports as the GUID is unpredictable. Is there a way how we can avoid this GUID subdirectory

Is there a way how we can avoid this GUID subdirectory

Unfortunately not, I opened an issue on vstest repo microsoft/vstest#2378 it's not related to coverlet.
