Code Coverage in .Net Core 2.0

Coverlet is a cross platform code coverage available as NuGet package.

Just add it on your test project:

dotnet add package coverlet.msbuild

And run it altogether with dotnet test command as parameter:

dotnet test /p:CollectCoverage=true

Supported Formats:

  • json (default)
  • lcov
  • opencover
  • cobertura

I made more detailed implementation about it here: .Net Core Unit Test and Code Coverage with Visual Studio Code


VSTest task cannot run .NET core tests as it uses the Test platform version 1. To run .NET core tests, we recommend using the .NET core task(preview) with the test command.

However, Code coverage and other data collection is not supported yet, no agent support.

We are fixing this issue as part of this https://github.com/Microsoft/vsts-agent/pull/1149/files Will update the thread once fix is gone and new agent is released. thread https://github.com/microsoft/vstest/issues/579#issuecomment-324401462
