# Bash Testing (BATS)
Test shell scripts reliably with the Bash Automated Testing System.
## Run tests
```bash
# Run a test file
bats test/my_script.bats
# Run all tests in directory
bats test/
# Verbose output
bats --verbose-run test/
# TAP format output (for CI)
bats --formatter tap test/
# Pretty output
bats --formatter pretty test/
```
## Write a test
```bash
# test/example.bats
#!/usr/bin/env bats
setup() {
# Runs before each test
source ./my_script.sh
}
teardown() {
# Runs after each test
rm -f /tmp/test_output
}
@test "function returns expected output" {
result=$(my_function "input")
[ "$result" = "expected output" ]
}
@test "script exits with code 0 on success" {
run ./my_script.sh --valid-arg
[ "$status" -eq 0 ]
}
@test "script exits with code 1 on bad input" {
run ./my_script.sh --invalid
[ "$status" -eq 1 ]
[[ "$output" =~ "Error" ]]
}
@test "output contains expected string" {
run ./my_script.sh
[ "$status" -eq 0 ]
[[ "$output" =~ "Success" ]]
}
@test "file is created" {
run ./my_script.sh --create /tmp/test_output
[ "$status" -eq 0 ]
[ -f /tmp/test_output ]
}
```
## Key assertions
```bash
# Exit status
[ "$status" -eq 0 ]
# Exact output match
[ "$output" = "expected" ]
# Regex match
[[ "$output" =~ "pattern" ]]
# Line-specific output
[ "${lines[0]}" = "first line" ]
[ "${lines[1]}" = "second line" ]
# File exists
[ -f "$filepath" ]
# String not empty
[ -n "$result" ]
# Numeric comparison
[ "$count" -gt 5 ]
```
## Using helper libraries
```bash
# With bats-support and bats-assert (install separately)
setup() {
load 'test_helper/bats-support/load'
load 'test_helper/bats-assert/load'
}
@test "readable assertions" {
run ./my_script.sh
assert_success
assert_output --partial "expected text"
refute_output --partial "error"
assert_line --index 0 "first line"
}
```
## Notes
- Install helpers: `git clone https://github.com/bats-core/bats-support test/test_helper/bats-support` and `git clone https://github.com/bats-core/bats-assert test/test_helper/bats-assert`.
- Use `setup_file()` / `teardown_file()` for expensive one-time setup.
- The `run` keyword captures both stdout and exit status into `$output` and `$status`.
- Tests run in subshells — variable changes don't leak between tests.
