45 """ Perform unittests using asynctest of osm_lcm.ns module
46 It allows, if some testing ENV are supplied, testing without mocking some external libraries for debugging:
47 OSMLCMTEST_NS_PUBKEY: public ssh-key returned by N2VC to inject to VMs
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
57 OSMLCM_VCA_XXX: configuration of N2VC
