Re: [libposix-development] [PATCH] strncpy implementation and tests

[Chris F. <ch...@fa...>]

I have no idea about cmake/ctest; I don't use them for my own stuff, since I try to avoid needing a C++ compiler.
Anyway, here's what I use for an embedded project. It's probably horrible in lots of ways, but it allows you to write tests like:

TEST( my_test_name )
{
	assert( blah );
}

or 

TEST( my_other_test, "somestubs.c", "someotherstubs.c" )
{
	assert( blah blah );
}

It's just two files:

$(PROJECT)/gentests.sh:

#!/bin/bash

# generate and run test wrappers
# c. forbes (ch...@fa...)

testsources=`grep -l "TEST(" *.c`
succeeded=0
failed=0

for f in $testsources
do
	echo -n "Searching for tests in \`$f\`... "
	tests=`grep "TEST(" $f | cut -d'(' -f 2 | cut -d, -f1 | cut -d')' -f1`
	echo `echo $tests | wc -w` found.

	for t in $tests
	do
		deps=`grep "$t" $f | cut -sd, -f2- | cut -d')' -f1`
		deps=`echo $deps | sed -e 's/[,\"]//g'`
#		echo $t deps: $deps 

		testbin=.test-$f-$t
		tmpsrc=`mktemp`.c
		cat > $tmpsrc << EOT
extern void __test__{{}}( void );

int main( int argc, char ** argv )
{
	__test__{{}}();
	return 0;
}
EOT
		cat $tmpsrc | sed -e "s/{{}}/$t/g" > $testbin.c
		gcc -DTEST_FRAMEWORK -o $testbin.elf -pipe $testbin.c $f $deps

		if ./$testbin.elf; then
#			echo SUCCESS
			let "succeeded=succeeded+1"
		else
#			echo FAILED
			let "failed=failed+1"
		fi
	done
done

rm .test*
if [ $failed = 0 ]; then
	echo "$succeeded tests passed."
else
	echo "FAILURES!!!"
	echo "$failed failed      $succeeded ok"
fi



$(INCLUDE)/testfx.h:

#ifndef _TESTFX_H
#define _TESTFX_H

#define TEST( test_name, ... )\
  void __test__ ## test_name( void )

#endif

 What do you have in mind ?

things in various places? The required plumbing can be done with just
sh+coreutils.

 But can it be done with CMake/CTest too ?
