Show coverage summary on terminal

Today at the end of the tests msbuil/.net tool drivers show a table with coverage result on console. For instance:

This is not supported at the moment for vstest collectors integration.

We use an another approach with the coverlet vstest collector on GitLab. Coverlet is configured to output the results as opencover format. After the test run a script extracts the coverage from the report and prints it to console.

PERCENTAGE=$(grep -m 1 -o -P '(?<=sequenceCoverage=")(\d+.\d+|\d+)' $DIRECTORY/coverage.opencover.xml)
echo "Line coverage: ${PERCENTAGE}%"

Thanks @MarcoRossignoli for working on this issue ASAP. this is the biggest blocker for us, using the vstest collector.
