Bats Testing Patterns

Acerca de

This skill provides Claude with expert-level guidance on the Bash Automated Testing System (Bats) to ensure shell scripts are reliable, portable, and maintainable. It covers essential testing patterns including environment setup and teardown, status and output assertions, file system verification, and advanced mocking or stubbing of external commands. It is particularly useful for developers building CLI tools, complex automation scripts, or CI/CD pipelines who want to apply Test-Driven Development (TDD) principles to shell environment utilities.
