# This is a "basic" test script for Microstack. It will install the
# microstack snap, spin up a test instance, and verify that the test
# instance is accessible, and can access the Internet.
#
# The multipass snap and the petname debian package must be installed
# on the host system in order to run this test.
#
# The basic test accepts two command line arguments:
#
# -u <channel> # First installs a released snap from the named
# # channel, in order to test basic upgrade functionality.
#
# -d <distro> # Specifies the distro of the multipass vm.
