Nano-node: how to create a testnet?

[pocesar]

Couldn't find any info on how to create a testnet to test integration with other services, how could this be done? And while at it, how the current acceptance tests work?

[jondwillis]

Not completely answering your question as to HOW to create a test net, but search through the code base for "rai_test_network" should turn up some answers.

[pocesar]

yeah, because sending useless 1 raw transactions to yourself in the mainnet for the sake of testing isn't a nice way to test heh

Well, here is my way:

1. Configure ACTIVE_NETWORK to rai_test_network with cmake gui tool and then rebuild the source.

2. Run rai_node with the following command:
   ./rai_node --daemon --data_path data-dir

3. Edit config.json in data-dir:
   set rpc_enable and enable_control to true

4.restart rai_node with the command in step 2

5.install raiblocks rpc library for python with the following command:
python -m pip install raiblocks

6.Test with the python code below:

from raiblocks import RPCClient
rpc = RPCClient('http://localhost:55000')
w = rpc.wallet_create()
print('wallet id:',w)

test_private_key = '34F0A37AAD20F4A260F0A5B3CB3D7FB50673212263E58A380BC10474BB039CE4'
test_account = rpc.wallet_add(w, test_private_key)
print('test genesis account:', test_account)

r = rpc.account_balance(test_account)
print('test_account balance:', r)

new_account = rpc.account_create(w)

r = rpc.account_balance(new_account)
print('balance of %s after account created:%s'%(new_account,r))

block_hash = rpc.send(w, test_account, new_account, 10000)
r = rpc.account_balance(new_account)
print('balance of %s after sent:%s'%(new_account,r))

rpc.receive(w, new_account, block_hash)
r = rpc.account_balance(new_account)
print('balance of %s after received:%s'%(new_account,r))

You will be able to see the following output:

wallet id: BBF38FB45A91B8AB43EBEEE1A59B598280FE0F0EC357070A9FA6793C30CDD250

test_account balance: {'balance': 340282366920938463463374607431768201455, 'pending': 0}
balance of xrb_151qb7uc6u5sn4tqgdqxr3kfsscnbqfdmx1ph1ffzaw7nbzpiyp7qtrxy7i8 after created account:{'balance': 0, 'pending': 0}
balance of xrb_151qb7uc6u5sn4tqgdqxr3kfsscnbqfdmx1ph1ffzaw7nbzpiyp7qtrxy7i8 after sent:{'balance': 0, 'pending': 10000}
balance of xrb_151qb7uc6u5sn4tqgdqxr3kfsscnbqfdmx1ph1ffzaw7nbzpiyp7qtrxy7i8 after received:{'balance': 10000, 'pending': 0}

7.Happy coding!

Thank @learnforpractice.

We can run testnet easily with Docker.

1. Build Docker image using testnet

./docker/node/build.sh -n test 

1. Start nano testnet

docker run -d \
    --name nano-testnet \
    -p 7075:7075/udp \
    -p 7075:7075 \
    -p 127.0.0.1:7076:7076 \
    -v RaiBlocksTest:/root/RaiBlocksTest \
    raiblocks-node-test

1. Test with Python code like above.
   https://github.com/dourvaris/nano-python

from nano import RPCClient


rpc = RPCClient('http://localhost:7076')

w = rpc.wallet_create()
print('wallet id:', w)

test_private_key = '34F0A37AAD20F4A260F0A5B3CB3D7FB50673212263E58A380BC10474BB039CE4'
test_account = rpc.wallet_add(w, test_private_key)
print('test genesis account:', test_account)

r = rpc.account_balance(test_account)
print('test_account balance:', r)

new_account = rpc.account_create(w)

r = rpc.account_balance(new_account)
print('balance of %s after account created:%s' % (new_account, r))


block_hash = rpc.send(w, test_account, new_account, 10000)
r = rpc.account_balance(new_account)
print('balance of %s after sent:%s' % (new_account, r))


rpc.receive(w, new_account, block_hash)
r = rpc.account_balance(new_account)
print('balance of %s after received:%s' % (new_account, r))

Another option is to use the Nano beta network, if a global network is needed.

I'm going to close this ticket since there appears to have been a response that is useful and no further follow-up from the requester.

If I want to build a testnet with a few peers, how can i do?
I have already run two single nodes in docker by the instruction given by @cuongtransc, but they cannot connect to each other even I have called ''work_peer_add" RPC.
Many thanks in advance!

[nengliangZ]

How can i connect two single nodes to make them sync with each other in this testnet?
I have run two nodes with the code given by @cuongtransc, but they are not connected even I have called 'work_peer_add' with RPC.
and I got the log:
`[2018-10-22 06:01:40.532523]: 0x7fa7b0004920 {"action": "account_create","wallet": "B3E4BC10D934B66F54038B91168453361337AF089DEEC70ABE079AD3AC4FBDF0"}
Any suggestions? Thanks in advance!
