brownie-token-tester's Issues

if already initialised as interface.ERC20, MintableForkToken Contract does not have mint attributes

Environment information

brownie Version: 1.17.0
brownie-token-tester Version: 0.3.2
ganache-cli Version: 6.12.2
Python Version: 3.9.10
OS: macos

What was wrong?

tokens that already have been initialised with brownie.interface.ERC20 do not have the mint attribute:

AttributeError: Contract 'ERC20' object has no attribute 'mint'

How can it be fixed?

instead of simply inheriting Contract, i think the MintableForkToken class should use a custom, hardcoded interface which extends brownie.interface.ERC20 with the necessary functions:

mint
updateGlobalPoolContract
createTokens
changeMaxSupply
issue
configureMinter

Functionality not available: I tired installing brownie-token-tester using pipx, pip and setuptools.
I am in anaconda environment and I can see it has been installed.

what command you ran
brownie run scripts/stake.py --network mainnet-fork-dev
the code that caused the failure in stake.py:

from brownie_tokens import MintableForkToken
....
dai = MintableForkToken(dai_addr)
