Kei Finance Testing Library

A comprehensive testing library for Ethereum smart contracts, featuring pre-configured setups for Uniswap V2/V3 testing environments.

Features

• Pre-configured Uniswap V2 and V3 testing environments
• Mock ERC20 tokens and WETH implementations
• Base testing utilities for common testing scenarios
• Foundry-compatible testing framework

Installation

yarn add @kei.fi/testing-lib

Usage

Basic Test Setup

Inherit from the base test contracts to access testing utilities:

import {BaseTest} from "@kei.fi/testing-lib/BaseTest.sol";

contract MyTest is BaseTest {
    function testSomething() public {
        // Your test code here
    }
}

Uniswap Testing

For Uniswap-specific testing, use the pre-configured environments:

import {UniswapTest} from "@kei.fi/testing-lib/UniswapTest.sol";

contract MyUniswapTest is UniswapTest {
    function testUniswapInteraction() public {
        // Access pre-deployed Uniswap contracts
        // uniswapV2Factory, uniswapV2Router02, uniswapV3Factory, etc.
    }
}
