To Test

First add a .secret file containing your 12 word mnemonic phrase to the root of the directory. This will be the account that does the transactions. Then add a .infura file containing the url for your infura node (if using infura, if using another node you will need to change how the web3 provider is set up in test/test.js).

Inside test.js in the test folder, change the TRADING_ADDRESS variable and Handler to the contract you wish to test and the contract's ApprovalHandler contract. If it is your first time using the contract, inside the test folder you'll need to run node test.js approve to approve your DAI tokens for trading.

Then, again inside the test folder run node test.js exchange where exchange is the DEX you want to test. This will test a 1 DAI-ETH trade on the DEX. You can add a dry option to see the trade data along with the gas price if the transaction would be succesful without actually sending the transaction (node test.js kyber dry).

Exchange options:

kyber

uniswap

multi (tests a 2 DAI-ETH multi dex trade between Uniswap and Kyber, 1 DAI on each DEX)
