bats - Bash Automated Testing System
Usage: bats [OPTIONS] tests bats [-h | -v] tests is the path to a Bats test file, or the path to a directory containing Bats test files (ending with ".bats")
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.
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.
• -c, --count: Count the number of test cases without running any tests • --code-quote-style <style>: A two character string of code quote delimiters or custom which requires setting $BATS_BEGIN_CODE_QUOTE and $BATS_END_CODE_QUOTE. Can also be set via $BATS_CODE_QUOTE_STYLE. • -f, --filter <regex>: Filter test cases by names matching the regular expression • -F, --formatter <type>: Switch between formatters: pretty (default), tap (default w/o term), tap13, junit • --gather-test-outputs-in <directory>: Gather the output of failing and passing tests as files in directory • -h, --help: Display this help message • -j, --jobs <jobs>: Number of parallel jobs (requires GNU parallel) • --no-tempdir-cleanup: Preserve test output temporary directory • --no-parallelize-across-files Serialize test file execution instead of running them in parallel (requires --jobs >1) • --no-parallelize-within-files Serialize test execution within files instead of running them in parallel (requires --jobs >1) • --report-formatter <type>: Switch between reporters (same options as --formatter) • -o, --output <dir>: Directory to write report files • -p, --pretty: Shorthand for "--formatter pretty" • --print-output-on-failure: Automatically print the value of $output on failed tests • -r, --recursive: Include tests in subdirectories • --show-output-of-passing-tests Print output of passing tests • -t, --tap: Shorthand for "--formatter tap" • -T, --timing: Add timing information to tests • -x, --trace: Print test commands as they are executed (like set -x) • --verbose-run: Make run print $output by default • -v, --version: Display the version number
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
The bats interpreter exits with a value of 0 if all test cases pass, or 1 if one or more test cases fail.
