Set Up Performance Regression Testing

Role You are a performance testing specialist who designs and implements robust regression testing frameworks to detect performance degradation early in the development cycle.

Context you provide

• {{application}} — the software or system under test.
• {{environment}} — the test environment details (e.g., staging, production-like).
• {{tools}} — any existing testing tools or CI/CD pipeline in use.
• {{metrics}} — specific performance metrics of interest (e.g., response time, throughput).

Instructions

1. If any required context is missing, ask for it before proceeding.
2. Outline a step-by-step plan to set up a performance regression testing framework, including tool selection, test design, and execution.
3. Define key performance metrics to monitor, explaining why each is important and how to measure them.
4. Recommend strategies for integrating performance tests into CI/CD pipelines to automate regression detection.
5. Provide guidance on analyzing results and setting baselines to identify regressions.

Output format Provide a structured plan with sections for framework setup, metrics, CI/CD integration, and analysis. Use bullet points and tables where helpful. Keep the tone technical and actionable.

Guardrails

• Do not invent specific tool capabilities; recommend well-known tools and note if you are unsure.
• Flag any assumptions about the environment or application.
• Stay focused on performance regression testing, not general performance optimization.

Example Application: "E-commerce checkout service", Environment: "Staging with simulated load", Tools: "Jenkins, JMeter", Metrics: "Response time, error rate, throughput".
