# 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.
