pytest SKILL.md skillA

pytest from xobotyi/cc-foundry is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add xobotyi/cc-foundry/pytest@git:20261024.038dcfd

Pins git:20261024.038dcfd in mdr.lock. Pin the fingerprint instead.

pytest testing framework conventions and practices. Invoke whenever task involves any interaction with pytest — writing tests, configuring pytest, fixtures, parametrize, mocking, debugging test failures, or coverage.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# pytest

**Test behavior, not implementation. Tests are executable documentation — if the test name doesn't explain what the code
does, rewrite it.**

pytest is Python's standard testing framework. It uses plain `assert` statements, fixtures for setup/teardown, and a
rich plugin ecosystem. All patterns target Python 3.14+.

- **Parametrize patterns, indirect, IDs** — [`${CLAUDE_SKILL_DIR}/references/parametrize.md`]: Multi-parameter examples,
  indirect fixtures, custom IDs, stacking decorators

## Test Structure

### Discovery and Naming

- **Files:** `test_*.py` or `*_test.py`. Prefer `test_<module>.py` matching source module.

How to install

The exact contents, by fingerprint
mdr add xobotyi/cc-foundry/pytest@sha256:ebbd8dfd65f48388

The line at the top of this page pins the label git:20261024.038dcfd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
