perftest

perftest is an Integration & environment testing skill for AI agents, published by mozilla-firefox in the firefox repository on GitHub. Skillspace rates perftest D (55/100) and it passed the safety scan; the rating is based on static analysis only.

Run Firefox performance tests locally or in CI. Use when the user asks how to run a perf test, needs the mach invocation for Raptor, Talos, MozPerftest, AWSY, or browsertime, wants to push perf tests to try, wants to run the tests belonging to an alert summary (`mach try perf --alert <id>`), or mentions `mach try perf`, `mach perftest`, `mach raptor`, or `mach talos-test`. Covers picking the right harness, finding a test's name, and the local-vs-CI tradeoff. Not for triaging or root-causing a Perfherder regression bug — confirming whether a regression is real, identifying the culprit patch, interpreting a PerfCompare result, or deciding backout vs fix-forward (use perf-regression-triage). Not for analyzing an existing Firefox profile (use profiler-analysis) or SpiderMonkey/JS engine benchmarking (use js-perf-investigation).
