Day 72: Consumer-Driven Contract Testing (Pact)

"Tired of breaking production every time a downstream API changes its field names? Traditional end-to-end tests are slow, brittle, and often too late to catch issues. Welcome to Day 72 of our Architect Series! In this video, we dive deep into Consumer-Driven Contract Testing (CDCT) using the Pact framework. You'll learn how to shift-left your integration testing by letting consumers define their requirements, ensuring your providers never break a contract again. What we cover: Why 100M RPS systems can't rely on E2E tests alone. The "Consumer-Provider" relationship. Generating Pact files and using a Pact Broker. A hands-on Spring Boot tutorial implementing a real-world contract. Don't let your microservices become a house of cards. Master the contract!"
