About Masterclass

Unit/contract tests prove a service works alone; users experience flows that span APIs - Kafka - databases. This masterclass teaches end-to-end (E2E) testing that validates real business journeys, catching integration, timing, and data issues before release.

Masterclass Outcomes

Test flows, not calls: e.g., Create Order - Order Placed - Inventory - Persist - Notify.
Tame eventual consistency: correlation IDs, resilient polling, idempotent endpoints.
Assert end-to-end: HTTP responses, Kafka payloads/schemas, and DB state.
De-flake suites: backoff, deterministic data, and disciplined timeouts.
