Foundry DeFi Stablecoin CodeHawks Audit Contest

Summary

I adjusted the AMOUNT_COLLATERAL in the conftest.py file in brownie framework and the unit test failed as liquidator_weth_balance>expected_weth + 55.

tests/unit/test_dsce.py:288: AssertionError
def test_liquidation_payout_is_correct(liquidated_dsce, liquidator):

assert expected_weth - 55 <= liquidator_weth_balance <= expected_weth + 55
E assert 611111111111111111111110 <= (611111111111111110555555 + 55)

AMOUNT_COLLATERAL = web3.toWei(1000000, "ether")
AMOUNT_DSC_TO_MINT = web3.toWei(101000000, "ether")
COLLATERAL_TO_COVER = web3.toWei(21000000, "ether")
