To launch the testnet you should use zombienet.
# First, make sure that the binaries `polkadot` and `sugondat-node` are in your PATH.
export PATH=/Users/pepyakin/dev/parity/polkadot/target/release/:$PATH
export PATH=/Users/pepyakin/dev/parity/sugondat-chain/sugondat-chain/target/release/:$PATH
# Then, launch the testnet.
#
# You will find logs in the `zombienet` directory.
#
# In order to relaunch the testnet, you should remove the `zombienet` directory.
./bin/zombienet-macos spawn -p native --dir zombienet testnet.toml
