This is a set of integration tests to be run against a live cluster.
You're going to want to make your own config.ini file in the /etc/ directory, it needs to point at your running cluster.
After that try commands such as:
run_tests.sh --nova run_tests.sh --glance run_tests.sh --swift run_tests.sh --auth
There are additional README files in the various subdirectories of this project.
