This repository contains testing utilities for ERC4626 vaults, including mocks that can simulate various failure modes and yield scenarios.
The main components are:
-
MockERC4626Tester: A mock ERC4626 vault that can:- Simulate different types of reverts (normal revert, out-of-gas, return bomb, etc.)
- Manipulate yield by increasing/decreasing the asset/share ratio
- Mint unbacked shares
- Configure decimals offset
-
MockERC20Tester: A mock ERC20 token for testing the vault with.
To use these utilities in your project, you use Foundry to install them as dependencies:
