Shortcuts for installing via WP-CLI. I have a Sites directory in my users directory where I create my tests. Replace items in all caps with proper values:

cd ~/Sites
mkdir sharon
cd sharon

wp core download
wp config create --dbname=DBNAME --dbuser=DBUSER --dbpass=DBPASS
wp db create
wp core install --url=URL.test --title="TITLE" --admin_user=ADMIN_USER --admin_password=ADMIN_PASSWORD --admin_email=YOUR@EMAIL.COM
