[LU-2873] The test-framework generates garbage while skipping tests

Fri, 22 Mar 2013 18:52:45 +0000

If we use ONLY variable, then the test-framework generates garbage in its output, that complicates log parsing, because of randomness behavior. For example, following command:

ONLY=6h /usr/lib64/lustre/tests/sanity.sh

can have following output:

ONLY=6h /usr/lib64/lustre/tests/sanity.sh 
Logging to shared log directory: /testing/aaaa/test_logs/1361270584

Where numerous dots ..... are generated garbage by run_test function, see 3285 line of test-framework.sh exerpt:

3267 run_test() {
3268     assert_DIR
3269 
3270     export base=`basetest $1`
3271     if [ ! -z "$ONLY" ]; then
3272         testname=ONLY_$1
3273         if [ ${!testname}x != x ]; then
3274             [ "$LAST_SKIPPED" ] && echo "" && LAST_SKIPPED=
3275             run_one_logged $1 "$2"
3276             return $?
3277         fi
3278         testname=ONLY_$base
3279         if [ ${!testname}x != x ]; then
3280             [ "$LAST_SKIPPED" ] && echo "" && LAST_SKIPPED=
3281             run_one_logged $1 "$2"
3282             return $?
3283         fi
3284         LAST_SKIPPED="y"
3285         echo -n "."
3286         return 0
3287     fi
3288

The reason is in this line:

3285         echo -n "."
