I've also created microsoft/vstest#1590

Steps to reproduce

• Create xunit test project dotnet new xunit
• Set environment variable SET TEAMCITY_PROJECT_NAME to some value to simulate running under TeamCity, for instance: SET TEAMCITY_PROJECT_NAME=my
• Run tests using some verbosity level: dotnet test --verbosity Minimal or dotnet test -v quiet

Expected behavior

You should find messages like ##teamcity[testStarted in stdOut
for all verbosity levels

Actual behavior

There are no any messages like ##teamcity[testStarted in stdOut

Environment

dotnet --version:
2.1.200
2.1.300-rc1-008673
