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

In addition to the good answers above, I find these three lines to be the simplest way to get it (which includes all packages):

go test -v -coverprofile cover.out ./YOUR_CODE_FOLDER/...
go tool cover -html=cover.out -o cover.html
open cover.html

Note that in the HTML file you will find a dropdown button that will direct you to all files.
