API Contract Testing and Schema Governance for Microservices at Enterprise Scale

Abstract

Author(s): David Rossi, Anika Patel, Mei O'Connor. This study explores api contract testing and schema governance for microservices at enterprise scale with a focus on practical engineering trade-offs in modern cloud-native environments. We present an implementation-driven methodology, reference architectures, and evaluation criteria that teams can adopt in quality engineering programs. Results highlight measurable improvements in reliability, security posture, and end-user performance when the proposed practices are applied.
