Performance Testing

Purpose: Validate system performance, scalability, and reliability under expected and peak loads. Scope: Load testing, stress testing, spike testing, soak testing, latency benchmarking, capacity planning.

When to Use This Skill

• Establishing performance baselines before release
• Validating SLA compliance (latency, throughput, error rate)
• Capacity planning for expected traffic growth
• Identifying bottlenecks in APIs, databases, or infrastructure
• Testing autoscaling behavior under load
• Regression testing after performance-sensitive changes
• Pre-production load validation
