git clone https://github.com/curvefi/curve-zaps.git
cd curve-zaps
pip install -r requirements.txt

Running the Tests

To run the entire suite:

brownie test --network <network_name>-fork

# network_name: mainnet (ethereum), optimism, xdai, polygon, fantom, arbitrum, avalanche

To run for particular pools:

brownie test --pools 3pool,compound,aave --network mainnet-fork
