Can I mock external commands with this skill?

Yes, the skill provides specific patterns for function-level mocking and command stubbing using PATH manipulation to isolate your scripts from external dependencies like curl or jq.

How do I integrate these tests into my CI/CD?

This skill includes ready-to-use configuration templates for GitHub Actions and Makefiles, allowing you to run your Bats suites automatically on every push.

Does this work for scripts intended for POSIX sh?

While Bats itself requires Bash to run the tests, this skill provides patterns for testing compatibility across different shell dialects including sh and dash.

Bats (Bash Automated Testing System) is a TAP-compliant testing framework for shell scripts that provides a simple syntax for assertions, fixtures, and parallel execution.

Security & Testing

Automates shell script verification using the Bash Automated Testing System (Bats) framework for robust and portable scripts.

This skill provides comprehensive patterns and best practices for writing production-grade unit tests for shell scripts using Bats. It covers fundamental test structures, advanced assertion logic, sophisticated mocking and stubbing of system commands, and seamless integration into CI/CD pipelines. By following these patterns, developers can implement Test-Driven Development (TDD) for shell utilities, ensuring they behave correctly across different environments and shell dialects while catching regressions early in the development lifecycle.
