python-testing SKILL.md skillA
python-testing from noesisvision/nasde-toolkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add noesisvision/nasde-toolkit/python-testing@git:20260323.75e7119Pins git:20260323.75e7119 in mdr.lock. Pin the fingerprint instead.

Python testing strategies using pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements.
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 Patterns
Comprehensive testing strategies for Python applications using pytest, TDD methodology, and best practices.
## When to Activate
- Writing new Python code (follow TDD: red, green, refactor)
- Designing test suites for Python projects
- Reviewing Python test coverage
- Setting up testing infrastructure
## Core Testing Philosophy
### Test-Driven Development (TDD)
Always follow the TDD cycle:
1. **RED**: Write a failing test for the desired behavior
2. **GREEN**: Write minimal code to make the test pass
3. **REFACTOR**: Improve code while keeping tests green
```python
# Step 1: Write failing test (RED)
def test_add_numbers():
result = add(2, 3)
assert result == 5
# Step 2: Write minimal implementation (GREEN)
def add(a, b):
return a + b
# Step 3: Refactor if needed (REFACTOR)
```
### Coverage Requirements
- **Target**: 80%+ code coverage
- **Critical paths**: 100% coverage required
- Use `pytest --cov` to measure coverage
```bash
pytest --cov=mypackage --cov-report=term-missing --cov-report=html
```
## pytest Fundamentals
### Basic Test Structure
```python
import pytest
def test_addition():
"""Test basic addition."""

How to install
mdr add noesisvision/nasde-toolkit/python-testing@sha256:b304a8c503af3264The line at the top of this page pins the label git:20260323.75e7119, 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.
