From ce9a7501ea29ddba61ef7c297223b3f7eca5a2a1 Mon Sep 17 00:00:00 2001 From: Lucian Musat Date: Tue, 15 Sep 2015 18:11:59 +0300 Subject: oeqa/decorators: Added decorator to restart the DUT in case of test hang. Once the DUT is hanged during testing, currently all the following test cases have to wait for default timeout to exit. Using this decorator the user can choose a timeout at case by case basis and what happens when the timeout is reached by overwriting the self.target.restart method.
