Bats-core: Bash Automated Testing System (2018)

Bats is a TAP-compliant testing framework for Bash. It provides a simpleway 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.

#!/usr/bin/env bats

@test "addition using bc" {
  result="$(echo 2+2 | bc)"
  [ "$result" -eq 4 ]
}

@test "addition using dc" {
  result="$(echo 2 2+p | dc)"
  [ "$result" -eq 4 ]
}

Bats is most useful when testing software written in Bash, but you can use it totest any UNIX program.

Test cases consist of standard shell commands. Bats makes use of Bash'serrexit (set -e) option when running test cases. If every command in thetest case exits with a 0 status code (success), the test passes. In this way,each line is an assertion of truth.

Why was this fork created?

There was an initial call for maintainers for the original Bats repository, but write access to it could not be obtained. With development activity stalled, this fork allowed ongoing maintenance and forward progress for Bats.
