Subject: Enadled --serial option for run_tests.sh
X-Git-Tag: 0.2~1672
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=66df82a76334015e3e2d25ddcc22b343b110320c;p=functest-xtesting.git

Enadled --serial option for run_tests.sh

It could be useful to execute e.g. Tempest test cases in a single
thread in order to troubleshoot possible concurrency problems.
