# Here is a list of testing tools that can be run with 'python' from a
# virtualenv in which Tahoe has been installed. There used to be Makefile
# targets for each, but the exact path to a suitable python is now up to the
# developer. But as a hint, after running 'tox', ./.tox/py27/bin/python will
# probably work.

# src/allmydata/test/bench_dirnode.py


# The check-speed and check-grid targets are disabled, since they depend upon
# the pre-located $(TAHOE) executable that was removed when we switched to
# tox. They will eventually be resurrected as dedicated tox environments.

# The check-speed target uses a pre-established client node to run a canned
# set of performance tests against a test network that is also
# pre-established (probably on a remote machine). Provide it with the path to
# a local directory where this client node has been created (and populated
# with the necessary FURLs of the test network). This target will start that
# client with the current code and then run the tests. Afterwards it will
# stop the client.
#
# The 'sleep 5' is in there to give the new client a chance to connect to its
# storageservers, since check_speed.py has no good way of doing that itself.
