What is Bats in the context of shell scripting?

Bats (Bash Automated Testing System) is a TAP-compliant testing framework that allows you to write tests for shell scripts with a simple, natural syntax, making it easier to verify script behavior.

Can I test scripts meant for different shells like Dash or Sh?

Yes, it includes patterns for validating script behavior across various shell dialects and environments to ensure portability and POSIX compliance.

Does it support CI/CD integration?

Absolutely, the skill includes ready-to-use patterns for integrating Bats tests into GitHub Actions workflows and Makefile-based build systems.

How does the skill handle temporary test files?

The skill covers advanced setup and teardown patterns using mktemp to create isolated test environments that are automatically cleaned up after test execution.

Can this skill help with mocking external commands?

Yes, it provides specific patterns for function mocking and command stubbing to isolate your scripts from external system dependencies during testing.

セキュリティとテスト

Implements comprehensive unit testing for shell scripts using the Bash Automated Testing System (Bats) framework.

概要

Bats Shell Testing Patterns provides Claude with the specialized expertise required to design, write, and maintain production-grade test suites for shell utilities and CI/CD pipelines. This skill enables the application of test-driven development (TDD) principles to shell scripting by providing a library of patterns for assertions, mocking external dependencies, and managing complex fixtures. Whether you are validating exit codes, capturing multi-line output, or ensuring cross-shell compatibility between Bash, Sh, and Dash, this skill helps create reliable, maintainable automation code that integrates seamlessly into modern DevOps workflows.
