Test

Pre requirements: Clone a key-exchange-server and near-smartcontracts. Deploy their docker instances:

⚠️ Please keep the order(near-smartcontracts depends on the key-exchange-server network)

1. key-exchange-server: bash docker-compose up -d
2. near-smartcontracts: bash docker-compose -f docker-compose.yml -f docker-compose.tests.yml up -d

Then:

docker-compose up
