What this skill does
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. When to Use This Skill Writing unit tests for shell scripts Implementing test-driven development (TDD) for scripts Setting up automated testing in CI/CD pipelines Testing edge cases and error conditions Validating behavior across different shell environments Building maintainable test suites for scripts Creating fixtures for complex test scenarios Testing multiple shell dialects (bash, sh, dash) Bats Fundamentals What is Bats? Bats (Bash Automated Testing System) is a TAP (Test Anything Protocol) compliant testing framework for shell scripts that provides: Simple, natural test syntax TAP output format compatible with CI systems Fixtures and setup/teardown support Assertion helpers Parallel test execution Installation File Structure Basic Test Structure Simple Test File Assertion Patterns Exit Code Assertions Output Assertions File Assertions Setup and Teardown Patterns Basic Setup and Teardown Setup with Resources Global Setup/Teardown Mocking and Stubbing Patterns Function Mocking Command Stubbing Variable Stubbing Fixture Management Using Fixture Files Dynamic Fixture Generation Advanced Patterns Testing Error Conditions Testing with Dependencies Testing Shell Compatibility Parallel Execution Test Helper Pattern testhelper.sh Integration with CI/CD GitHub Actions Workflow Makefile Integration Best Practices 1. Test one thing per test - Single responsibility principle 2. Use descriptive test names - Clearly states what is being tested 3. Clean up after tests - Always remove temporary files in teardown 4. Test both success and failure paths - Don't just test happy path 5. Mock external dependencies - Isolate unit under test 6. Use fixtures for complex data - Makes tests more readable 7. Run tests in CI/CD - Catch regressions early 8. …
