Distributed Systems and Microservices Testing Questions

Covers strategies and best practices for testing applications composed of multiple services and distributed components. Topics include integration and end to end testing across service boundaries, handling eventual consistency and asynchronous interactions, managing service dependencies and startups in test pipelines, designing resilient tests that are robust to infrastructure changes, contract testing between services, service virtualization and mocking of downstream systems, test data management for distributed environments, and techniques to reduce flakiness such as retries, idempotent test design, and observability and logging to diagnose failures.
