EXECUTING TEST 1
[2017-09-15T11:08:49.433932] End of scenario
Test scenario 'technique' failed on platform 'centos7'

• broken policy generation (the path of the technique to test is invalid - it is directly /var/rudder/configuration-repository/techniques/1.0 - so missing mandatory technique name)
• system techniques are empty (/var/rudder/configuration-repository/techniques/system/common is empty)
