    Sample input

    Create a Locust test plan and script for our new checkout API. We expect 500 concurrent users at peak, and I need to make sure we don't exceed a 2s response time for the 95th percentile.

    Sample output

    I've scaffolded a Locust project for your Checkout API. It includes a modular locustfile.py with custom LoadTestShape for the 500-user ramp-up, environment variable support for API keys, and a --check-p95 2000 validation handler to fail the CI build if response times exceed your SLA.

    About This Skill

    Professional Performance Testing Strategy & Automation

    Transform vague performance requirements into rigorous, ISTQB-aligned testing suites. This skill acts as a senior performance architect and Locust expert to help you design, scaffold, and review enterprise-grade load tests.

    What it does

    • Test Planning: Generates comprehensive, risk-based performance test plans following ISTQB standards.
    • Workload Modeling: Converts user personas into technical operational profiles and multi-stage load schedules (Ramp-up, Soak, Stress, Spike).
    • Locust Scaffolding: Builds complete, modular Python Locust projects with industry-standard script patterns, environmental variable handling, and CI/CD readiness.
    • Quality Assurance: Validates generated scripts via syntax checks and provides a scorecard for existing plans to identify gaps in monitoring or strategy.
    • SLA Guidance: Recommends measurable NFRs and baseline approaches when production data or requirements are missing.

    Why use this skill?

    Generic AI prompts often produce brittle, "hello world" load scripts that lack realistic pacing, fail to handle secrets, or ignore critical failure thresholds. This skill ensures your testing is methodologically sound, safe for your infrastructure, and produces results that stakeholders can actually trust for sign-off.

    Use Cases

    • Construct ISTQB-aligned performance test plans from high-level requirements.
    • Generate modular, maintainable Locust suites with realistic workload shapes.
    • Audit existing test plans using a 100-point rubric for risk and coverage.
    • Define discovery-based baselines when formal SLAs or NFRs are unavailable.
    • Model complex user personas into technical load profiles for realistic testing.
