Implements comprehensive unit testing for shell scripts using the Bash Automated Testing System (Bats) framework.
This skill equips Claude with specialized knowledge to write, debug, and maintain production-grade test suites for shell scripts and CLI utilities. It covers advanced Bats patterns including status code assertions, multi-line output verification, file-system state testing, and sophisticated mocking techniques for external commands. Whether you are building robust CI/CD pipelines or practicing test-driven development (TDD) for DevOps scripts, this skill ensures your shell automation is reliable, portable, and error-resistant across various shell dialects and environments.
