runtime-load-stress-validation

To validate API latency, you simulate peak concurrency using deterministic workload modeling across HTTP, gRPC, and async workers. This process applies stage-based load tests to measure p50/p95/p99 latencies against predefined SLOs and generates evidence artifacts for delivery sign-off.

Runtime stress testing pushes services beyond normal capacity to find saturation points and breaking limits, while standard load testing applies expected peak traffic to verify stability. You choose between load, stress, spike, or soak modes to target specific resilience scenarios and measure throughput degradation.

Yes, you can measure message queue and async worker throughput. The testing workflow applies deterministic workload modeling across HTTP, message queues, and realtime paths, capturing throughput, error rates, and concurrency behavior to ensure reproducible test stages.

For runtime SLO validation, you need to capture p50, p95, and p99 latencies, error rates, throughput, and saturation behavior. Measuring these metrics against defined thresholds provides remediation guidance and evidence artifacts for service delivery sign-off.

You should run soak tests to evaluate long-term memory leaks and sustained throughput degradation, whereas spike tests validate sudden traffic surges. Both modes capture latency percentiles and error rates, but soak tests reveal saturation behavior over extended durations.

To set up reproducible load testing stages, you select a mode and provide the target gRPC or HTTP endpoint. The workflow applies deterministic workload modeling with predefined SLOs, thresholds, and acceptance criteria to ensure consistent test execution and measurable results.
