The validation utility is engineered as an intermediary CI/CD and data quality gate. It accepts two inputs: an authoritative JSON Schema definition provided by upstream producers, and ingested JSON sample payloads recorded from real-world telemetry or staging queues. It…
You need deterministic, fast feedback from each service before you push a change across teams. Isolated testing is the pragmatic way to give you that feedback—it lets you validate a microservice's business logic, persistence, and API contract without bringing…
