Scream Testing

 Scream testing is a practice used to determine whether a legacy service, server, API, or component is still in use by temporarily disabling or shutting it down and waiting to see if anyone complains "screams". 

 In modern software architecture and cloud infrastructure, orphan dependencies and zombie assets frequently remain active without clear documentation or ownership. While it carries operational risk and should be treated as a last resort with an immediate rollback strategy, scream testing helps teams identify hidden downstream dependencies, clean up technical debt, and decommission unused systems safely.
