How does Bats handle temporary files during tests?

These patterns utilize setup and teardown functions along with mktemp to create isolated work directories that are automatically cleaned up after each test run.

How do I mock external commands using these patterns?

The skill demonstrates both function-based mocking and PATH-based command stubbing to isolate your scripts from external dependencies during testing.

What is the Bash Automated Testing System (Bats)?

Bats is a TAP-compliant testing framework for shell scripts that provides a simple syntax for assertions, setup/teardown fixtures, and parallel execution.

Can I use this skill to test scripts in CI/CD?

Yes, this skill provides specific patterns and YAML templates for integrating Bats tests into GitHub Actions and other automated pipeline environments.

Does this skill help with shell portability?

Absolutely. It includes patterns for testing scripts against multiple shell dialects including bash, POSIX sh, and dash to ensure your utilities work across environments.

セキュリティとテスト

Provides comprehensive guidance and implementation patterns for testing shell scripts using the Bash Automated Testing System (Bats).

概要

This skill equips Claude with advanced knowledge of the Bash Automated Testing System (Bats) to help developers write robust, production-grade unit tests for shell scripts. It covers everything from basic assertions and setup/teardown logic to sophisticated mocking of external commands, file fixture management, and CI/CD integration. Use this skill when building reliable CLI tools, shell-based utilities, or complex DevOps automation scripts that require a test-driven development (TDD) approach and cross-shell compatibility validation.
