Tests must be run as root on machine with sfcbd broker.
There are number of environment variables, that affect test running:
  LMI_CIMOM_USERNAME
  LMI_CIMOM_PASSWORD
  LMI_CIMOM_BROKER
  LMI_CIMOM_URL
  LMI_RUN_DANGEROUS      - valid values: 0, 1
  LMI_SOFTWARE_USE_CACHE - valid values: 0, 1
    - says, whether to use cache to download rpm packages, which will
      be used to speed up testing
  LMI_SOFTWARE_CACHE_DIR 
    - directory, where to store rpm packages and other information
    - if not set and LMI_SOFTWARE_USE_CACHE == '1', a temporary
      directory will be created and deleted, when tests are
      complete

Simple usage:
  Each test module can be run as a stand-alone script or with run_tests.py
  script:
    $ ./run_tests.py -c --cache-dir=/var/tmp
  To pass any arguments to underlying unittest.main() function, append them
  after "--" swith like this:
    $ ./run_tests.py -c --cache-dir=/var/tmp -- -v TestSoftwarePackage
  All environment variables defined above can be overriden by command-line
  arguments.
