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.
