# This testcase simply checks that the DHT command-line tools work.
# It launches a single peer, stores a value "testdata" under "testkey",
# and then gives the system 50 ms to fetch it.
#
# This could fail if
# - command line tool interfaces fail
# - DHT plugins for storage are not installed / working
# - block plugins for verification (the test plugin) is not installed
#
# The code does NOT depend on DHT routing or any actual P2P functionality.
