Sua infraestrutura se comporta como deveria? Da maneira mais simples: Behavior Driven Infrastructure é BDD para infraestrutura. Quotando James Turnbull: systems testing should be about behaviour not about metrics. Who cares if the host is up and reports normal load if it doesn’t do the ACTUAL job it’s designed to: server web pages, send and receive email, resolve hosts, authenticate, backup and restore, etc, etc.
