Unit Tests

To run the unit tests suite (in Javascript), you'll need to manually run Hardhat in order to enable ESM support:

node --require esm ./node_modules/.bin/hardhat test --network hardhat

Alternatively, you can run a local Hardhat node in another terminal using

yarn chain --network hardhat

then run the following:

yarn test

It might happens that Hardhat cannot resolve custom error (test failing on "Expecter nameOfTheError() but reverted without a reason string"), just restart yarn chain.

System Tests

End-to-end tests have been written in Solidity, using Foundry.

To get set up:

  1. Install Foundry.
curl -L https://foundry.paradigm.xyz | sh
  1. Install external lib(s)
git submodule update --init
  1. Run tests:
forge test
  1. Update Foundry periodically:
foundryup

Coverage

To check current unit tests coverage:

node --require esm ./node_modules/.bin/hardhat coverage --network hardhat

A few notes:

  • Hardhat doesn't support esm yet, hence running manually with node.
  • We are currently using a forked version of solidity-coverage that includes optimizer settings. Ideally we will move to the maintained version after this is fixed on their end.
  • Juicebox V2 codebase being quite large, Solidity Coverage might run out of memory if you modify/add parts to it. Please check Solidity-coverage FAQ in order to address the issue.

Deploy

Juicebox uses the Hardhat Deploy plugin to deploy contracts to a given network. But before using it, you must create a ./mnemonic.txt file containing the mnemonic phrase of the wallet used to deploy. You can generate a new mnemonic using this tool. Generate a mnemonic at your own risk.

Then, to execute the ./deploy/deploy.js script, run the following:

npx hardhat deploy --network $network

_You'll likely want to set the optimizer runs to 10000 in ./hardhat.config.js before deploying to prevent contract size errors. The preset value of 1000000 is necessary for hardhat to run unit tests successfully. Bug about this opened here.

Contract artifacts will be outputted to ./deployments/$network/** and should be checked in to the repo.

Verification

To verify the contracts on Etherscan, make sure you have an ETHERSCAN_API_KEY set in your ./.env file. Then run the following:

npx hardhat --network $network etherscan-verify

This will verify all of the deployed contracts in ./deployments.
