Bats Testing Patterns

What it does

Bats Testing Patterns provides actionable guidance, templates, and patterns for testing shell scripts with Bats (Bash Automated Testing System). It explains setup/teardown, common assertion styles (exit codes, output, files), fixture management, mocking/stubbing techniques, CI integration, and parallel test strategies so engineers can build reliable, maintainable shell test suites.

When to use it

Use this skill when you need to: write unit tests for shell scripts; introduce test-driven development for bash utilities; add automated script tests into CI/CD; verify behavior across shell dialects (bash, sh, dash); or create reproducible fixtures and mocks for complex script scenarios. It's aimed at developers, DevOps engineers, and CI authors working with shell tooling.

What's included

• Scripts: none bundled in the SKILL.md (has_scripts=false) — the doc includes many example snippets you can copy.
• References: none listed in sibling files (has_references=false) — links in the body point to bats-core and documentation.
• Instructions: practical examples covering file/assertion patterns, setup/teardown, global setup/teardown, mocking/stubbing, fixture generation, CI (GitHub Actions) workflow snippets, and Makefile/test integrations. The skill contains ready-to-use test templates and recommended practices for reliable test suites.

Compatible agents

Best consumed by code-oriented assistants and agents that can provide or edit repository files (e.g., Claude Code, Copilot/GitHub Copilot, Codex-style tools) or configure CI workflows.
