From 09590ac76a19ee1b1b4a9188f7fce5029f0de52a Mon Sep 17 00:00:00 2001 From: Markus Lehtonen Date: Wed, 29 Jun 2016 19:45:41 +0300 Subject: oeqa.buildperf: introduce runCmd2() Special runCmd() for build perf tests which doesn't raise an AssertionError when the command fails. This causes command failures to be detected as test errors instead of test failures. This way "failed" state of tests is reserved for future making it possible to set e.g. thresholds for certain measurement results.
