部署升级测试

# 环境变量配置
export PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

# 部署第一版本的合约
forge script ./script/UUPSContractV1Script.sol:UUPSContractV1Script  --rpc-url 127.0.0.1:8545 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --broadcast

升级前测试

cast send --rpc-url 127.0.0.1:8545 0xB7f8BC63BbcaD18155201308C8f3540b07f84F5e  "setValue(uint256)" 100 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
cast call --rpc-url 127.0.0.1:8545 0xB7f8BC63BbcaD18155201308C8f3540b07f84F5e  "value()(uint256)"

部署第二版本合约

部署第二版合约时需要执行：forge clean && forge build

forge script ./script/UUPSContractV2Script.sol:UUPSContractV2Script  --rpc-url 127.0.0.1:8545 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --broadcast

升级后测试

cast call --rpc-url 127.0.0.1:8545 0xB7f8BC63BbcaD18155201308C8f3540b07f84F5e  "value()(uint256)"
