Performance Test Plan

Performance Test Plan

Core Workflow

1. Identify performance goal, user journey or endpoint, expected load, baseline, environment, and release risk.
2. Choose metrics: latency percentiles, throughput, error rate, resource use, Core Web Vitals, query time, queue lag, or job duration.
3. Define test setup, data, traffic model, warmup, duration, and pass/fail thresholds.
4. Include profiling and observability needed to diagnose failures.
5. Separate synthetic, local, staging, and production-safe checks.
6. Add regression gates and follow-up tuning options.

Safety Rules

• Do not run load tests against production without explicit approval and a safe window.
• Do not invent baseline numbers or capacity claims.
• Verify current platform-specific performance metrics from official docs when exact definitions matter.

Deliverable Shape

For performance test plans, provide:

• Target and goal
• Metrics and thresholds
• Environment and data
• Traffic model
• Test steps
• Observability and profiling
• Regression gate
• Risks and follow-up
