Pytest Dev

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
lang:python
World-class pytest engineer for Python: write/refactor tests, fix flakiness, design fixtures/markers, add coverage, speed up suites (collection/runtime), and optimize CI (GitHub Actions sharding, xdist parallelism, caching). Use when asked about pytest best practices, pytest 9.x features (subtests, strict mode, TOML config), pytest plugins (xdist/cov/asyncio/mock/httpx), or test performance/CI tuning.

From the source SKILL.md

Produce high-signal, low-flake, fast pytest suites and CI configs, with an explicit focus on measurable wins (runtime, flake rate, coverage quality).
