Contract-Based Testing in Microservices

This chapter explores the concept of contract-based testing, particularly in the context of microservices, using Swagger to define and manage REST API contracts. It emphasizes the importance of establishing contracts prior to coding to ensure compatibility and facilitate communication between services, as well as discussing strategies for backwards compatibility and API evolution at Landbay. The chapter also addresses the distinction between contract testing and functional business testing, highlighting how the former ensures smooth service interaction rather than content verification.
