ChaosMockApi – Mock APIs with integrated chaos testing for resilient systems

Summary: ChaosMockApi combines API mocking with chaos engineering by simulating failures, latency, and outages to build resilient systems. It enables creating pipelines of responses that introduce controlled chaos, reflecting real-world unpredictable conditions. This approach helps test retry logic, fallbacks, and error handling as they occur in production environments.

What it does

ChaosMockApi allows defining sequential responses for the same endpoint and injecting latency, errors, throttling, and dropped connections. It can proxy real requests to third-party APIs while applying chaos to simulate production-like failures.

Who it's for

It is designed for developers and teams building mission-critical, microservices-based systems requiring realistic testing beyond predictable mocks.

Why it matters

It addresses the gap in testing caused by assuming perfect conditions, enabling validation of system resilience under real-world failure scenarios.
