Run package Tests

1. Run the test backend in one of the terminals

cd backend
cartesi build
cartesi run

2. Open a new terminal to deploy the ERC721 contract and mint the NFT used for tests

export MNEMONIC="test test test test test test test test test test test junk"
export RPC_URL="http://localhost:8545"
export PUBLIC_KEY="0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC"
export ERC721_ADDRESS="0x36C02dA8a0983159322a80FFE9F24b1acfF8B570"

cd backend/contracts

forge build

forge create --rpc-url "${RPC_URL}" --mnemonic "${MNEMONIC}" --json src/simpleERC721.sol:SimpleERC721

cast send --mnemonic "${MNEMONIC}" --rpc-url "${RPC_URL}" ${ERC721_ADDRESS} "mintTo(address)" ${PUBLIC_KEY}

3. Go Back to cartesi-client root dir and run the tests

cd ../../

npm run test
