From f49f27f1bc67d07440b0ac9a7d767a8ea1589bfe Mon Sep 17 00:00:00 2001 From: Alexander Kanavin Date: Tue, 15 Dec 2015 15:50:44 +0200 Subject: [PATCH 5/5] Modify vg_test wrapper to support PTEST formats Change the valgrind regression test script vg_regtest to support the yocto ptest stdout reporting format. The commit adds '--yocto-ptest' as an optional argument to vg_regtest, which alters the output to use the ptest infrastructure reporting format: "[PASS|SKIP|FAIL]: testname" instead of valgrind's internal test reporting format. Without the added option, --yocto-ptest, the valgrind regression test output is unchanged. Enforce 30 seconds limit for the test. This resume execution of the remaining tests when valgrind hangs.
