NAME

       bats - Bash Automated Testing System

SYNOPSIS

       bats [-c] [-p | -t] test [test ...]

       test is the path to a Bats test file, or the path to a directory containing Bats test files.

DESCRIPTION

       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.

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

       See bats(7) for more information on writing Bats tests.

RUNNING TESTS

       To  run your tests, invoke the bats interpreter with a path to a test file. The file´s test cases are run
       sequentially and in isolation. If all the test cases pass, bats exits with a 0 status code. If there  are
       any failures, bats exits with a 1 status code.

       You  can  invoke  the  bats  interpreter with multiple test file arguments, or with a path to a directory
       containing multiple .bats files. Bats will run each test file individually and aggregate the results.  If
       any test case fails, bats exits with a 1 status code.

OPTIONS

       -c, --count
              Count the number of test cases without running any tests

       -h, --help
              Display help message

       -p, --pretty
              Show results in pretty format (default for terminals)

       -t, --tap
              Show results in TAP format

       -v, --version
              Display the version number

OUTPUT

       When you run Bats from a terminal, you´ll see output as each test is performed, with a check-mark next to
       the test´s name if it passes or an "X" if it fails.

           $ bats addition.bats
            ✓ addition using bc
            ✓ addition using dc

           2 tests, 0 failures

       If  Bats  is  not  connected  to  a terminal--in other words, if you run it from a continuous integration
       system or redirect its output to a file--the results are displayed  in  human-readable,  machine-parsable
       TAP format. You can force TAP output from a terminal by invoking Bats with the --tap option.

           $ bats --tap addition.bats
           1..2
           ok 1 addition using bc
           ok 2 addition using dc

EXIT STATUS

       The bats interpreter exits with a value of 0 if all test cases pass, or 1 if one or more test cases fail.
