How to measure code coverage in Golang?

Question

Has anyone succeeded in generating code coverage for Go unit tests? I can\'t find a tool for that on the web.

Answer 1

Inspired by the help menus and other answers to this question, just run:

f=cover.out; if [ -f $f ]; then rm $f; fi; go test ./... -coverprofile $f && \
go tool cover -html $f && \
rm $f
