How do I clean up files after a test runs?

Bats provides a teardown() function that runs automatically after every test case, allowing you to safely remove temporary directories and files created during the test.

Can Bats tests be integrated into GitHub Actions?

Yes, Bats produces TAP (Test Anything Protocol) output which is easily consumed by CI/CD tools, and it can be installed via npm or homebrew in runner environments.

What is Bats (Bash Automated Testing System)?

Bats is a TAP-compliant testing framework for Bash that provides a simple way to verify the behavior of shell scripts through automated assertions.

How do I mock external commands in shell tests?

You can mock commands by creating temporary function overrides or by placing stub scripts in a high-priority directory within the PATH during the test execution.

Security & Testing

Master the Bash Automated Testing System (Bats) to implement robust, unit-tested shell scripts and CI/CD pipelines.

About

This skill provides comprehensive patterns and best practices for using Bats-core to test shell scripts. It guides developers through creating natural test syntax, managing complex fixtures, and implementing advanced mocking and stubbing for external commands. Whether you are building simple utility scripts or complex DevOps automation, this skill ensures your shell code is reliable, portable across different dialects like Bash and Dash, and ready for production-grade CI/CD environments.

Key Features

Advanced mocking and command stubbing techniques for isolated unit testing
Integration-ready TAP output patterns for GitHub Actions and Makefiles
Robust setup and teardown patterns for managing temporary test environments
Cross-shell compatibility testing for Bash, Sh, and Dash environments
0 GitHub stars
Comprehensive assertion library for exit codes, output strings, and file states

Use Cases

Implementing Test-Driven Development (TDD) for complex shell utilities
Validating infrastructure-as-code and CI/CD pipeline scripts before deployment
Ensuring shell script portability and regression safety across multiple platforms
