Run TestUniswapTPS is a test case to measure the transactions per second (TPS) of Uniswap. The test case follows these steps: 1. Arrange

• Create a deployer user with sufficient balance
• Create multiple test users with initial balance
• Deploy Uniswap core contracts (WETH9, UniswapV2Factory, UniswapV2Router01)
• Deploy a set of ERC20 token contracts
• Approve the router contract to spend tokens on behalf of test users
• Distribute the test tokens to each test user
• Generate all possible token pairs from the deployed ERC20 tokens
• Add liquidity to the token pairs on Uniswap

2. Act

• Each test user performs a series of token swaps on Uniswap
• The swaps are performed concurrently to simulate real-world usage

3. Assert

• Calculate and report the transactions per second (TPS) achieved during the test
