Modern test framework for Maker repositories to get up and running with MCD faster. Extends forge-std.
First do forge install makerdao/dss-test (or dapp equivalent) in your newly setup repository.
Look at src/tests/IntegrationTest.t.sol for a bunch of examples.
There is a special GodMode library which provides useful functions such as giving auth access to an arbitrary contract or setting token balances to any amount.
A DssInstance is mostly just for keeping a bundle of references to all the common mcd contracts. If you are doing integration testing this can be loaded from the chainlog automatically with MCD.loadFromChainlog(). MCD also provides some high level functions:
initIlk(...)- This will deploy a new ilk to theDssInstancealong with standard liquidation and oracle components.
MCDUser instances can be used to interact with MCD. They represent the end users and can perform any number of actions. Usually what you will want to do is inherit this contract and extend the functionality to whatever library you are building. MCDUser provides some high level functions:
createAuction(address join, uint256 amount)- Kicks off a new auction for the specifiedjoinadapter for theamountof collateral specified.
