How do I handle temporary test files and directories?

The skill recommends using setup() and teardown() functions with 'mktemp -d' to create isolated temporary environments for each test, ensuring no side effects remain after the test suite runs.

What is Bats in shell scripting?

Bats (Bash Automated Testing System) is a TAP-compliant testing framework for Bash that provides a simple way to verify that shell scripts behave as expected using a natural syntax.

How do I mock external commands in Bats tests?

You can mock commands by creating a directory of 'stubs' (executable scripts), adding that directory to the beginning of your PATH during the test setup, and removing it during teardown.

Can Bats be used in CI/CD pipelines?

Yes, Bats is designed for CI/CD. It can output results in the Test Anything Protocol (TAP) format, which is easily consumed by tools like GitHub Actions, Jenkins, and GitLab CI.
