I want to track test coverage on a go project using Coveralls, the instructions for the integration reference using https://github.com/mattn/goveralls
cd $GOPA
In Go 1.13, following command generates coverage for multiple packages
go test -v -coverpkg=./... -coverprofile=profile.cov ./... go tool cover -func profile.cov
for html report
go tool cover -html=profile.cov -o cover.html
