[dev] Shell script testing functions
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() {
