ERC4626 Testing Utilities

Introduction

This repository contains testing utilities for ERC4626 vaults, including mocks that can simulate various failure modes and yield scenarios.

Overview

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.

Usage

To use these utilities in your project, you use Foundry to install them as dependencies:
