How would you design a system that incorporates Test-Driven Development (TDD) across multiple services in a microservices architecture, ensuring each service maintains high test coverage?

COVER // HOW WOULD YOU DESIGN A SYSTEM THAT INCORPORATES TEST-DRIVEN DEVELOPMENT (TDD) ACROSS MULTIPLE SERVICES IN A MICROSERVICES ARCHITECTURE, ENSURING EACH SERVICE MAINTAINS HIGH TEST COVERAGE?

I would start by defining clear interfaces and contracts between services, then ensure each service has its own suite of unit and integration tests built using TDD principles. Continuous integration should be set up to automatically run tests whenever changes are made, and I would advocate for shared testing libraries to standardize approaches across services.
