Before following the guide, you should be familiar with GPG and Keybase... oh and Linux ofcourse!

The dollar sign($) means the terminal input.

Requirements

- gpg # which is preinstalled in linux
- git
- zsh
- oh-my-zsh

Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

	#!/usr/bin/env bash
	#shellcheck disable=SC2016

	set -euo pipefail

	if [[ -z "${DOTLY_PATH:-}" ]] \|\| ! output::empty_line > /dev/null 2>&1; then
	red='\033[0;31m'
	green='\033[0;32m'
	bold_blue='\033[1m\033[34m'
	normal='\033[0m'

	{
	"AL": {
	"name": "Alabama",
	"capital": "Montgomery",
	"lat": "32.361538",
	"long": "-86.279118"
	},
	"AK": {
	"name": "Alaska",
	"capital": "Juneau",

	# Clean the exited containers
	docker rm $(sudo docker ps -a \| grep Exit \| cut -d ' ' -f 1)

	# Clean the untagged images (or old images)
	docker rmi $(docker images \| tail -n +2 \| awk '$1 == "<none>" {print $'3'}')

	# On Docker 1.9+ you can remove the orphan volumes with the next command
	docker volume rm $(docker volume ls -qf dangling=true)
