Writing Tests for Shell Scripts

Writing Tests for Shell Scripts

Testing shell scripts using Bats-core (Bash Automated Testing System):

# test/math.bats
@test "addition calculates correctly" {
    result="$(./calc.sh 2 3)"
    [ "$result" -eq 5 ]
}

@test "missing argument throws exit code 1" {
    run ./calc.sh
    [ "$status" -eq 1 ]
}
