# 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 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.
# -m # Run tests in a multipass machine.
# -d <distro> # Ubuntu distro of the multipass machine to run tests
# # within. Defaults to bionic.
