pytest-test-generator_skill

Overview

This skill automates generation of pytest tests and related configurations for Python projects. It helps produce unit and integration test scaffolding, fixtures, mocks, and CI-friendly test layouts. Use it to accelerate test coverage, enforce patterns, and produce runnable pytest code samples.

How this skill works

The skill inspects the target code, test requirements, and project layout to propose pytest test functions, fixtures, and parametrized cases. It generates code snippets, configuration files (pytest.ini, tox, or GitHub Actions), and suggests mocking or dependency-injection points. Outputs are validated against common pytest conventions and basic linting rules.

When to use it

• When you need scaffolded pytest tests for existing functions or modules
• When creating fixtures, parametrized tests, or mocking strategies
• When configuring CI test runs or pytest.ini / tox setups
• When you want production-ready test templates following pytest best practices
• When improving or expanding test coverage quickly

Best practices

• Generate small, isolated unit tests that assert one behavior per test
• Use fixtures for shared setup and parametrization for multiple input cases
• Prefer monkeypatch or unittest.mock for external dependencies to avoid network I/O
• Include clear arrange-act-assert structure and meaningful test names
• Add CI configuration that runs tests in a clean environment and fails fast

Example use cases

• Create pytest test skeletons for a new Python module with typical edge cases
• Auto-generate fixture-based integration tests for database access using transaction rollbacks
• Produce parametrized tests for function inputs and expected outputs
• Generate pytest.ini and GitHub Actions workflow to run tests on push and pull requests
• Suggest mock patterns and example mocks for external APIs or filesystem interactions
