How can I mock external commands like curl in my shell tests?

This skill provides patterns for mocking by overriding commands with local functions or using shellspec's dedicated 'Mock' syntax to simulate responses without making actual network calls.

Which Bash testing framework should I choose?

Use shunit2 if you need a simple, portable, xUnit-style framework for basic unit testing. Choose shellspec for a more modern, feature-rich BDD approach that is better suited for complex projects and behavior-driven specs.

How do I test Bash functions that require user interaction?

The skill demonstrates how to use heredocs and the 'printf' command to pipe simulated user input into interactive prompts, allowing for automated testing of 'yes/no' confirmations and data entry.

Can I test if a script exits with a specific error code?

Yes, the skill includes patterns for capturing the exit status ($?) and asserting its value using framework-specific matchers like 'assertEquals' in shunit2 or 'The status should eq' in shellspec.

Security & Testing

Streamlines shell script validation by providing standardized patterns and frameworks for unit testing and behavior-driven development.

The Bash Testing skill equips developers with the necessary tools and implementation patterns to build robust test suites for shell scripts using industry-standard frameworks like shunit2 and shellspec. It provides comprehensive guidance on xUnit-style unit testing, BDD-style specifications, and advanced mocking techniques to isolate script logic from the environment. Whether you are validating exit codes, capturing stdout/stderr, or simulating interactive user input, this skill ensures your automation scripts remain reliable, maintainable, and production-ready through rigorous testing practices.
