You can inject network delays and HTTP errors during load tests by leveraging the xk6-disruptor extension within Grafana k6 to simulate faults directly into Kubernetes services. This validates system stability under degraded conditions.

Yes, you can test circuit breaker functionality by simulating a partial outage in k6, such as injecting a 10% error rate and 500ms delays into critical APIs. This observes how your system handles degraded performance and measures recovery.

For chaos engineering in Kubernetes, you can inject HTTP errors, gRPC errors, network delays, and pod terminations into your services. This allows you to proactively identify system weaknesses by simulating real-world failure scenarios.

Grafana k6 supports pod termination fault injection for resilience testing through the xk6-disruptor extension. This allows you to validate system behavior, test recovery mechanisms, and measure recovery times during active load tests.

You validate system recovery mechanisms during a Kubernetes load test by injecting faults like gRPC errors and network delays, then observing how the system handles the degraded performance and recovers. This proactively identifies resilience weaknesses.
