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

Coverage Report →

a) Run all the tests and enable coverage --> go test ./... -coverprofile coverage.out

b) Get coverage for individual functions as well as overall coverage → go tool cover -func coverage.out

c) See the lines covered and the ones not covered by your tests → go tool cover -html=cover.out -o coverage.html. Open the coverage.html file hereby generated in the browser and analyze the detailed coverage info.
