Esto puede ser muy útil para configurar **recursos** que necesitas usar para toda la app, y que son **compartidos** entre requests, y/o que necesitas **limpiar** después. Por ejemplo, un pool de conexiones a una base de datos, o cargando un modelo de machine learning compartido.

## Caso de Uso { #use-case }

package cmd

import (
	"testing"
)

func TestNewRequestID(t *testing.T) {
	// Ensure that it returns an alphanumeric result of length 16.
	id := mustGetRequestID(UTCNow())

	if len(id) != 16 {
		t.Fail()
	}

	var e rune
	for _, char := range id {
		e = char

		// Ensure that it is alphanumeric, in this case, between 0-9 and A-Z.
		isAlnum := ('0' <= e && e <= '9') || ('A' <= e && e <= 'Z')

Agora que sabemos a diferença entre os termos **processo** e **programa**, vamos continuar falando sobre implantações.
