# Bats Testing Patterns Comprehensive guidance for writing comprehensive unit tests for shell scripts using Bats (Bash Automated Testing System), including test patterns, fixtures, and best practices for production-grade shell testing. ## Use this skill when - Writing unit tests for shell scripts - Implementing TDD for scripts - Setting up automated testing in CI/CD pipelines - Testing edge cases and error conditions - Validating behavior across shell environments ## Do not use this skill when - The project does not use shell scripts - You need integration tests beyond shell behavior - The goal is only linting or formatting ## Instructions - Confirm shell dialects and supported environments. - Set up a test structure with helpers and fixtures. - Write tests for exit codes, output, and side effects. - Add setup/teardown and run tests in CI. - If detailed examples are required, open `resources/implementation-playbook.md`. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples.
