# this is a smoke-test using "./bin/tahoe" to:
|
||||
#
|
||||
# 1. create an introducer
|
||||
# 2. create 5 storage nodes
|
||||
# 3. create 2 client nodes (client0 = alice, client1 = bob)
|
||||
# 4. Alice creates a magic-folder ("magik:")
|
||||
# 5. Alice invites Bob
|
||||
# 6. Bob joins
|
||||
#
|
||||
# After that, some basic tests are performed; see the "if True:"
|
||||
# blocks to turn some on or off. Could benefit from some cleanups
|
||||
# etc. but this seems useful out of the gate for quick testing.
|
||||
#
|
||||
# TO RUN:
|
||||
# from top-level of your checkout (we use "./bin/tahoe"):
|
||||
# python src/allmydata/test/check_magicfolder_smoke.py
|
||||
#
|
||||
# This will create "./smoke_magicfolder" (which is disposable) and
|
||||
# contains all the Tahoe basedirs for the introducer, storage nodes,
|
||||
# clients, and the clients' magic-folders. NOTE that if these
|
||||
# directories already exist they will NOT be re-created. So kill the
|
||||
# grid and then "rm -rf smoke_magicfolder" if you want to re-run the
|
||||
# tests cleanly.
|
||||
#
|
||||
# Run the script with a single arg, "kill" to run "tahoe stop" on all
|
||||
# the nodes.
|
||||
#
|
||||
# This will have "tahoe start" -ed all the nodes, so you can continue
|
||||
# to play around after the script exits.
