I sometimes enjoy testing my shell scripts. Opinions?

#!/bin/sh

tap_inited=false
tap_i=0
tap_exitstatus=0

tap_printline()
{
[ "$1" -eq 0 ] && printf "ok %d - %s\n" $tap_i "$current" && return;

printf "not ok %d - %s\n" $tap_i "$current"
exitstatus=1
}

tap_test() {
lastexitstatus=$?

! $tap_inited && current="$1" && tap_inited=true && tap_pretest && return;
tap_i=$((tap_i+1))

tap_printline $lastexitstatus
tap_posttest
current=$1
tap_pretest
}

tap_printplan() {
printf "1..%s\n" "$tap_i"
}

tap_finish() {
lastexitstatus=$?
[ -z "$current" ] && exit
tap_printline $lastexitstatus
tap_printplan
exit $exitstatus
}

trap tap_finish EXIT

tap_pretest() {
true
}

tap_posttest() {
true
}

tap_test "one plus zero is zero"
sum=$((1+0))
[ sum -eq 0 ]

tap_test "one plus one is one"
sum=$((1+1))
[ sum -eq 2 ]

tap_test "one plus one is three"
sum=$((1+1))
[ sum -eq 3 ]

tap_test "two plus two is four"
sum=$((2+2))
[ sum -eq 4 ]
