From ffba215ff0d6e2f840740bbca4c09e12d38c572e Mon Sep 17 00:00:00 2001 From: Susant Sahani Date: Jun 29 2018 12:39:17 +0000 Subject: Adds tests according to the CI justification Adds tests according to the CI wiki specifically the standard test interface in the spec. The playbook includes Tier1 level test cases that have been tested in the following contexts and is passing reliably: Classic. Test logs are stored in the artifacts directory. The following steps are used to execute the tests using the standard test interface: Test enveronment Make sure you have installed packages from the spec ``` ansible-2.4.1.0-2.fc28.noarch python2-dnf-2.7.5-1.fc28.noarch libselinux-python-2.7-2.fc28.x86_64 standard-test-roles-2.5-1.fc28.noarch ``` Run tests for Classic Snip of the example test run for Classic tests: ``` :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: Test :: Test :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: [ 17:42:55 ] :: [ LOG ] :: Starting libnet tests ... :: [ 17:42:55 ] :: [ LOG ] :: Starting libnet tests ... :: [ 17:42:55 ] :: [ BEGIN ] :: Running '/usr/bin/test-libnet' [==========] Running 2 test(s).
