Bats-core: Bash Automated Testing System

Bats is a TAP-compliant testing framework for Bash. It provides a simple way to verify that the UNIX programs you write behave as expected. A Bats test file is a Bash script with special syntax for defining test cases. Under the hood, each test case is just a function with a description. Bats is most useful when testing software written in Bash, but you can use it to test any UNIX program.
