What problem does it solve?
This Skill provides a structured approach to implementing and maintaining robust Python tests using pytest, TDD, fixtures, mocking, and coverage benchmarks, reducing debugging time and increasing software quality.
Core Features & Use Cases
- Test-Driven Development (TDD): Emphasizes red-green-refactor cycles to guide design and implementation.
- Comprehensive Testing Patterns: Fixtures, parametrization, mocking, and asynchronous test patterns for Python projects.
- Code Coverage & Quality Gate: Guidance to achieve 80%+ coverage on critical paths and maintainable test suites.
- Use Case: A developer adds a new feature to a Python module, writes tests following TDD, runs pytest with coverage, and iterates until the suite passes and coverage goals are met.
Quick Start
To start applying this skill, install Python and pytest, create a simple test file (e.g., test_sample.py), and run tests with coverage:
- Install Python and pytest
- Write a basic pytest test
- Run pytest --cov --cov-report=term-missing
