[LTP] [PATCH] run-posix-option-group-test.sh: Log and exit if one attempts to run tests without compiling

[shatur.linux]

From: Sharan Turlapati <sturlapati@vmware.com>

Currently, run-posix-option-group-test.sh erroneously
logs "***Tests Completed***" when no test has actually run if the script is invoked
to run without actually compiling the tests.

Check if the .run-test files actually exist before attempting to run them.
If not found, log a message indicating the problem and suggest to check if
the tests were compiled. Exit the script without attempting to run other
tests.

Can you please describe how this happen? open POSIX failed to compile?

[[ ]] are bashisms, we require support for POSIX shell (i.e. dash, busybox sh)

TL;DR: simply use:
if [ -n "$list_of_tests" ]; then
NOTE [ ] require using quotes (unlike [[ ]]).

You can check similar error yourself:
$ checkbashisms run-posix-option-group-test.sh
possible bashism in run-posix-option-group-test.sh line 26 (alternative test command ([[ foo ]] should be [ foo ])):
	if [[ -n $list_of_tests ]]

All is described in:
https://github.com/linux-test-project/ltp/wiki/Test-Writing-Guidelines#22-shell-coding-style

I'd prefer slightly different version:
* check for error first, then for can be out of else (readability)
* add local

run_option_group_tests()
{
	local list_of_tests

	list_of_tests=`find $1 -name '*.run-test' | sort`

	if [ -z "$list_of_tests" ]; then
		echo ".run-test files not found under $1. Were the tests compiled?"
		exit 1
	fi

	for test_script in $list_of_tests; do
		(cd "$(dirname "$test_script")" && ./$(basename "$test_script"))
	done
}

Kind regards,
Petr

OK, you noted this in the commit message.

Merged with fixed bashism, improved style and commit message.

Thanks!

Kind regards,
Petr
