testing-perf
Load and performance tests with k6 and Locust, plus pytest speed (xdist). Use when writing load tests or speeding up a test suite.
Why this skill is useful
Provides specific performance testing patterns and executable scripts for k6 and Locust that the AI wouldn't reliably generate on its own.
What it needs
Requires k6, locust installed locally. About 3k tokens when loaded. Last updated 2026-08-06. 215 stars on the source repository.
What this skill does
Performance & Load Testing Patterns Focused skill for performance testing, load testing, and pytest execution optimization. Covers k6, Locust, pytest-xdist parallel execution, custom plugins, and test type classification.

Auto extension provisioning: k6 run pulls required extensions automatically; manual xk6 build is superseded for most workflows. Browser module import: import browser from 'k6/browser' — the old k6/experimental/browser path was removed in v0.52+. Any generated code using /experimental/ will fail. OTLP output built in: k6 run --out experimental-opentelemetry=... — stream results straight to your tracing backend. …
