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.
