Start a local environment: npx hardhat node

OPTIONAL: Start a mainnet forked env: npx hardhat node --fork https://eth-mainnet.alchemyapi.io/v2/1Ywbr_Hku2pWR5BTgV9hxyoGaDWX0AoF *currently a bit tempramental, use cautiously

then run the environment of choice, eg. npx hardhat run ./environments/development.ts --network localhost

then run the unit tests of choice, eg. npx hardhat test test/011_oracle.ts --network localhost
