python-testing SKILL.md skillA

python-testing from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add athola/claude-night-market/python-testing@git:20260902.4a35d69

Pins git:20260902.4a35d69 in mdr.lock. Pin the fingerprint instead.

Python testing patterns with pytest, fixtures, TDD, mocking, async and integration tests. Use when writing or auditing a Python test suite.

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

# Python Testing Hub

Testing standards for pytest configuration, fixture management, and TDD implementation.

## Quick Start

1.  **Dependencies**: `pip install pytest pytest-cov pytest-asyncio pytest-mock`
2.  **Configuration**: Add the following to `pyproject.toml`:
    ```toml
    [tool.pytest.ini_options]
    testpaths = ["tests"]
    addopts = "--cov=src"
    ```
3.  **Verification**: Run `pytest` to confirm discovery of files matching `test_*.py`.

## When To Use

- Constructing unit and integration tests for Python 3.9+ projects.
- Isolating external dependencies using `pytest-mock` or custom monkeypatching.
- Validating asynchronous logic with `pytest-asyncio` markers and event loop management.
- Configuring project-wide coverage thresholds and reporting.

## When NOT To Use

- Evaluating test
  quality - use pensive:test-review instead
- Infrastructure test
  config - use leyline:pytest-config

## Modules

This skill uses modular loading to manage the system prompt budget.

### Core Implementation
- See `modules/unit-testing.md` - AAA (Arrange-Act-Assert) pattern, basic test structure, and exception validation.

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/python-testing@sha256:00ee3e6d50c69a2b

The line at the top of this page pins the label git:20260902.4a35d69, 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.
