How does this skill help with mocking shell commands?

It provides specific patterns for function overriding and PATH manipulation, allowing you to intercept calls to external tools like curl, git, or docker to simulate various scenarios without running the actual commands.

Can these testing patterns be used in CI/CD?

Yes, the skill includes patterns for setting up test infrastructure, managing temporary directories, and organizing fixtures that are essential for stable execution in GitHub Actions or other CI environments.

What is Bats in the context of shell testing?

Bats (Bash Automated Testing System) is a TAP-compliant testing framework for Bash that allows you to write tests in a format similar to standard shell scripts to verify command output and behavior.

Does it handle differences between Linux and macOS?

Yes, the skill includes platform-specific guidance, such as handling the different flags required for the 'stat' command when checking file permissions on Linux versus macOS.

Security & Testing

Provides comprehensive patterns and best practices for writing automated shell script tests using the Bats framework.

About

This skill equips Claude with specialized knowledge for creating robust Bash test suites using the Bash Automated Testing System (Bats). It includes detailed implementation patterns for verifying exit codes, asserting multi-line command output, and performing complex file system checks. Users can leverage this skill to implement advanced testing techniques like command stubbing via PATH manipulation, function mocking, and efficient fixture management, ensuring shell scripts remain reliable, maintainable, and bug-free throughout the development lifecycle.

Key Features

Advanced setup and teardown patterns for test isolation and global resource management
Automated fixture management for organizing and generating dynamic test data
Comprehensive assertions for exit codes, multi-line output, and regex matching
0 GitHub stars
Command stubbing and mocking techniques using PATH manipulation and environment variables
Platform-specific guidance for cross-platform Linux and macOS shell testing compatibility

Use Cases

Implementing automated testing pipelines for infrastructure-as-code shell wrappers
Developing unit and integration tests for complex Bash utility scripts and CLI tools
Mocking external API calls or CLI tools to test script logic in isolated environments
