To write unit tests for shell scripts using Bats, you install bats-core, create test files under a tests directory, and execute them with the bats command to validate shell utility behavior.

Best practices for Bats test structure involve using setup and teardown functions for fixture management, enforcing deterministic tests, and applying consistent assertion strategies to ensure reliable shell utility validation.

Mocking commands in Bats tests involves creating stub functions within the test environment to intercept shell utility calls, ensuring deterministic test execution and isolated assertion validation.

Bats testing supports cross-shell compatibility and CI integration by enforcing deterministic tests and best practices across setup, teardown, and assertions to build reliable CI pipelines for shell utilities.

You should use Bats for shell script testing to automate robust validation of shell utilities, leveraging its specialized patterns for fixtures, mocking, and cross-shell compatibility within maintainable test suites.
