Setting up Gitlab CI for Golang Project

After searching how to set up gitlab CI for my golang project for a while (probably 1.5 day). I wanna take some note here to save your time.

The flow is basically talking to gitlab API.

The step is:
1. Get the output
Either from gitlab runner log or artifact
with Golang, It is the output from command: go test ./...

2. Config the regex for gitlab CI to parse the output from all runner
Setting -> CI/CD -> General Pipelines
Fill regex in section Test coverage parsing

That’s all.
You can do the whole process with .gitlab-ci.yml without touching gitlab UI page by specifying coverage in .gitlab-ci.yml file

You can also change the label of showing the result in
Setting -> General -> Badges
