SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Performance testing enables teams to quantify API/UI responsiveness, validate SLA compliance, and uncover bottlenecks before production.

Core Features & Use Cases

  • Load testing to measure throughput and latency under normal conditions.
  • Stress and spike testing to identify failure points and recovery behavior.
  • Frontend performance budgets with Lighthouse CI and resource budgets.
  • Profiling and benchmarking across API, frontend, and database interactions.

Quick Start

Run a baseline load test against your API or UI using the provided script and configure thresholds to match your SLA.

Frequently Asked Questions about performance-tester

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate API load testing to measure SLA adherence?▼

You can automate API load testing using k6 to simulate traffic and measure latency against configurable SLA thresholds. This generates structured output artifacts that quantify throughput and identify backend bottlenecks under normal load conditions.

What is the difference between stress and spike testing for APIs?▼

Stress testing identifies API failure points by pushing load beyond normal capacity, while spike testing evaluates recovery behavior during sudden traffic surges. Both techniques uncover performance bottlenecks and validate system resilience before production deployment.

How do I set up frontend performance budgets with Lighthouse CI?▼

Set up frontend performance budgets with Lighthouse CI by configuring audit thresholds for resource loading and UI responsiveness. This generates structured performance reports that enforce front-end budgets and identify rendering bottlenecks across web application components.

Can I profile database interactions and API latency together?▼

Yes, you can profile database interactions and API latency together by running benchmarks across backend and frontend components. This integrated profiling identifies bottlenecks across database queries and API endpoints to quantify overall system responsiveness.

What is soak testing and when do I need it for API performance validation?▼

Soak testing evaluates API performance and memory stability under sustained load over extended periods. You need it to uncover memory leaks and ensure long-term SLA compliance before deploying applications to production environments.
