  48     OSMLCMTEST_NS_NAME: change name of NS
  49     OSMLCMTEST_PACKAGES_PATH: path where the vnf-packages are stored (de-compressed), each one on a 'vnfd_id' folder
  50     OSMLCMTEST_NS_IPADDRESS: IP address where emulated VMs are reached. Comma separate list
  51     OSMLCMTEST_RO_VIMID: VIM id of RO target vim IP. Obtain it with openmano datcenter-list on RO container
  52     OSMLCMTEST_VCA_NOMOCK: Do no mock the VCA, N2VC library, for debugging it
  53     OSMLCMTEST_RO_NOMOCK: Do no mock the ROClient library, for debugging it
  54     OSMLCMTEST_DB_NOMOCK: Do no mock the database library, for debugging it
  55     OSMLCMTEST_FS_NOMOCK: Do no mock the File Storage library, for debugging it
  56     OSMLCMTEST_LOGGING_NOMOCK: Do no mock the logging
