• Experience with API clients, test-data builders, configuration management, reusable assertions, cleanup, and reporting.
• Experience preventing flaky tests and supporting safe parallel execution.

7. Microservices and Asynchronous Systems

• Understanding of eventual consistency, retries, idempotency, circuit breakers, concurrency, and partial failures.
• Ability to validate asynchronous outcomes using bounded polling and meaningful timeout handling.

8. Kafka and Event-Driven Testing

• Ability to inspect Kafka topics, keys, headers, payloads, partitions, offsets, and consumer behavior.
• Experience validating event publication, consumption, duplicates, ordering, retries, and dead-letter handling.

9. Mocking and Test Environments

• Experience with Mockito, WireMock, or equivalent tools.
• Ability to simulate dependency behavior, errors, and timeouts.
• Experience managing test configuration, dependencies, and isolated data.
• Familiarity with Testcontainers is desirable.

10. Database and Data Validation

• Proficiency in SQL, including joins, filtering, and aggregation.
• Ability to compare JSON payloads, validate persisted state, and reconcile data across services.

11. Commerce, Payments, and Orders

• Understanding of cart, checkout, pricing, promotions, tax, shipping, inventory, payment authorization/capture/void/refund, order creation, fulfillment, and cancellation.
• Ability to validate complete flows and regional variations.

12. Integration and Downstream Validation
