-"""
-vstart_runner: override Filesystem and Mount interfaces to run a CephFSTestCase against a vstart
-ceph instance instead of a packaged/installed cluster. Use this to turn around test cases
-quickly during development.
-
-Simple usage (assuming teuthology and ceph checked out in ~/git):
-
- # Activate the teuthology virtualenv
- source ~/git/teuthology/virtualenv/bin/activate
- # Go into your ceph build directory
- cd ~/git/ceph/build
- # Invoke a test using this script
- python ~/git/ceph/qa/tasks/vstart_runner.py --create tasks.cephfs.test_data_scan
-
-Alternative usage:
-
- # Alternatively, if you use different paths, specify them as follows:
- LD_LIBRARY_PATH=`pwd`/lib PYTHONPATH=~/git/teuthology:~/git/ceph/qa:`pwd`/../src/pybind:`pwd`/lib/cython_modules/lib.2 python ~/git/ceph/qa/tasks/vstart_runner.py
-
- # If you wish to drop to a python shell on failures, use --interactive:
- python ~/git/ceph/qa/tasks/vstart_runner.py --interactive
-
- # If you wish to run a named test case, pass it as an argument:
- python ~/git/ceph/qa/tasks/vstart_runner.py tasks.cephfs.test_data_scan
