How Contract Testing Prevented Microservices Breaking Changes

When a fintech team with 15 microservices was spending 20 hours per week on regression testing just to avoid breaking downstream consumers, they turned to consumer-driven contract testing with Pact. In this episode, we break down how they shifted ownership of API contracts to the consumers, automated verification in CI, and reduced production incidents by 40 percent. We also explore the practical trade-offs — like the overhead of maintaining pact files and handling versioning — and how this approach fits into a broader quality strategy. If your team has ever deployed a change only to find out it broke someone else's integration, this episode is for you. #ContractTesting #Microservices #Pact #ConsumerDrivenContracts #SoftwareEngineering #TechPodcast #FexingoBusiness #BusinessPodcast #Tech #Engineering #QualityAssurance #API #DevOps #Testing #AutomatedTesting #CI/CD #ContinuousDelivery #Reliability Keep every episode free: buymeacoffee.com/fexingo
