# The 'run' performs a simple test that verifies that STI image.
# The main focus here is to exercise the STI scripts.
#
# IMAGE_NAME specifies a name of the candidate image used for testing.
# The image has to be available before this script is executed.
#
# For each client package test, XXX_REVISION specifies which
# branch or tag should be tested; by default it uses the latest
# released version as reported by `npm show XXX version` where
# XXX is the name of the npm package.
#
# For each client package XXX_REPO must be defined in this
# test file to set the repository that corresponds to the
# npm package XXX.
