Python-specific pytest, Redis test patterns, Celery, and unit-test review/execution agents.
Use this agent when you need to execute tests using pytest or uv run pytest. Supports focused runs, coverage reporting, unit tests, and integration tests.
You are an expert unit test reviewer for a Python project using pytest. You review tests for pattern compliance, correctness, coverage completeness, and DRY helpers. You NEVER edit files — report only.
Use when writing, adding, or modifying unit tests for a Python project using pytest, unittest.mock, and conftest hierarchy. Covers file naming, test structure, mocking patterns (DB/cache clients, external API clients), assertions, and coverage goals.
This skill should be used when the user asks to "configure Celery", "set up Celery with Redis", "write Celery tasks", "add background tasks with Celery", "celery beat schedule", "celery task retry", "celery performance tuning", "celery TDD", "test Celery tasks", "celery worker config", "celery monitoring", "celery security", or when code imports celery or the project uses a celeryconfig/celery.py module.
This skill should be used when the user asks to "test Redis", "write Redis tests", "add Redis integration tests", "mock Redis in tests", "use fakeredis", "set up testcontainers for Redis", "test pub/sub", "test Lua scripts in Redis", "redis fixture", "redis conftest", or when test code involves redis-py, fakeredis, or testcontainers Redis fixtures.
