bats-testing-patterns
Allows your agent to comprehensively test shell scripts using Bats. It's ideal for CI/CD pipelines and test-driven development.
What it does
This tool helps you create automatic tests for your command-line scripts (shell scripts). It ensures your scripts work as expected by checking their output, errors, and other behaviors.
When to use it
- ✓When writing tests for scripts you've created.
- ✓When you want to ensure your scripts function correctly in various scenarios.
- ✓To automate script verification within continuous integration (CI/CD) processes.

Bats Testing Patterns
Comprehensive guidance for writing comprehensive unit tests for shell scripts using Bats (Bash Automated Testing System), including test patterns, fixtures, and best practices for production-grade shell testing.
Use this skill when
- Writing unit tests for shell scripts
- Implementing TDD for scripts
- Setting up automated testing in CI/CD pipelines
- Testing edge cases and error conditions
- Validating behavior across shell environments
Do not use this skill when
- The project does not use shell scripts
- You need integration tests beyond shell behavior
- The goal is only linting or formatting
Instructions
- Confirm shell dialects and supported environments.
- Set up a test structure with helpers and fixtures.
- Write tests for exit codes, output, and side effects.
- Add setup/teardown and run tests in CI.
- If detailed examples are required, open
resources/implementation-playbook.md.
Resources
resources/implementation-playbook.mdfor detailed patterns and examples.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
FAQ
What are 'shell scripts'?
They are small programs that run directly in your computer's terminal, used to automate tasks.
What is 'CI/CD'?
It's a way to automate the software development and delivery process, where tests are run automatically.
What are 'unit tests'?
These are tests that check small parts of a program (like a function or a script) in isolation to ensure they work correctly.
