How to run bcoin on testnet?

In the documentation you can specify a network param, but the default main network name isn't the same as bitcoind (livenet). What is the name of testnet on bcoin?

EDIT: When going by the documentation and adding network: testnet to bcoin.conf, I get the error

AssertionError [ERR_ASSERTION]: Unknown network.

My bcoin.conf file is

network: testnet
prefix: ~/.bcoin
prune: true
http-port: 8332
api-key: ******
uri: http://localhost

Are you referring to http://bcoin.io/ ??

Yep! And alternate to bitcoind – arshbot – 2017-07-16T19:45:20.100

Just curious what is the advantage of bcoin to bitcoind? – Marc Alexander – 2017-07-17T19:00:45.687

Very modular, entirely written in node.js, has an extensive api built out so you can easily build on top of a node (previously only possible with bitcore), and has an active team whose focus seems to be making this more developer friendly. For example, I'm building a mobile wallet with bcoin as a local backend (without using the node functionality). You can't do that with bitcoind. – arshbot – 2017-07-18T14:42:08.380

This might be as a result of a previous ChainDB having been initialized at ~/.bcoin/chain.ldb/ . You can find information inside of the debug.log file. e.g.

[I:2017-07-17T09:11:47Z] (chaindb) Opening ChainDB... [E:2017-07-17T09:11:47Z] (node) Network mismatch for chain.

create a new location for the chain, e.g. ~/.bcoin/testnet/
copy the above config with the updated prefix as per the above
execute bcoin --prefix ~/.bcoin/testnet/

Default prefix is "~/.bcoin/", you can override this by using the prefix cli flag

To add to this, you can specify a config file with bcoin --config=~/.bcoin/bcoin.conf (your config location) or you can set a different config file in the testnet or main folder and bcoin should pick it up – arshbot – 2017-07-18T14:46:19.293

As stated by the configuration page, you set

network: testnet

In your bcoin.conf file.

See the question again, I updated it with an error related to this solution (provided by the documentation) – arshbot – 2017-07-16T19:44:32.130

Did you add the network: testnet to your config file? – MattyAB – 2017-07-16T19:46:26.330

Yes, the error occurs when using that config file. The command I use to specify the conf file is bcoin -config=~/.bcoin/bcoin.conf – arshbot – 2017-07-16T19:49:45.913
