A simple testing framework for bash scripts
Test your bash scripts in the fastest and simplest way.
Why bashunit
A lightweight, fast testing framework for Bash 3.0+, focused on developer experience. It ships 93 assertions plus spies, mocks, data providers, snapshots and more.
Quick start
Install the latest version into your project:
curl -s https://bashunit.com/install.sh | bash
Write a test in tests/example_test.sh:
#!/usr/bin/env bash
function test_bashunit_is_working() {
assert_same "bashunit is working" "bashunit is working"
}
Run it:
./lib/bashunit tests/
Assertions at a glance
One representative example per family — the full catalogue and every signature is at
bashunit.com/assertions, or run bashunit doc locally:
| Family | Example |
|---|---|
| Equality & truth | assert_equals "foo" "$actual" |
| Strings | assert_string_starts_with "Hello" "$greeting" |
| Exit codes | assert_exit_code "1" (checks $? of the previous command) |
| Numeric | assert_greater_than "1" "$count" |
| Arrays | assert_array_length 3 "${my_array[@]}" |
| Files & dirs | assert_file_permissions 644 "$file" |
JSON (needs jq) |
assert_json_contains ".name" "bashunit" "$json" |
| Dates | assert_date_before "2026-01-01" "$date" |
| Duration | assert_duration_less_than "echo hello" 500 |
| Snapshots | assert_match_snapshot "$(my_cmd)" |
| Test doubles | assert_have_been_called_times 2 my_fn |
Documentation
Full documentation, covering installation options, every feature and examples, lives at bashunit.com.
Shell tab-completion for bash and zsh is available under completions/ — see the installation docs.
Using an AI coding agent? bashunit.com/ai-agents covers machine-readable
results and the API traps that make generated bash tests pass for the wrong reason. The docs are also
published as plain text at llms.txt and
llms-full.txt, with a drop-in skill at
bashunit-skill.md.
