solidity合约事务性测试

目标：验证交易具有事务性
结果：具有事务性

1. 部署合约
   部署成功后，查询初始化数据：

2. 测试交易

• name 传参为空，然后调用getUsers。
  结果：交易回滚了，data合约里也没有存储数据。

• name 传参，然后调用getUsers。
  结果：data和voting合约都存储了数据。

合约demo示例

3. 逻辑合约

// SPDX-License-Identifier: GPL-3.0

pragma solidity >=0.7.0 <0.9.0;

import "./data.sol";
import "./voting.sol";

contract Logic {
    Data private _data;
    voting private _voting;
    constructor(address dataAddr, address votingAddr){
        _data = Data(dataAddr);
        _voting = voting(votingAddr);
    }

    function getUsers(string memory name) public view returns(Data.User[] memory){
        if(bytes(name).length >0){
            Data.User[] memory _users = new Data.User[](1) ;
            _users[0] =_data.getUsers()[0];
            return _users;
        }
        return _data.getUsers();
    }

     function addUserAndProposal(string memory name, uint age) public{
        Data.User memory newUser;
        newUser.name=name;
        newUser.age=age;
        //
        _data.addUser(newUser);
        //
        _voting.addProposal(name);
    }

}

2. 数据合约

// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;

contract Data {
     
    struct User {
        string name;
        uint age;
    }
    // 
    User[] private users;
    
    constructor() {
        users.push(User("zxl",1));
        users.push(User("zxl2",2));
        users.push(User("zxl3",3));
    }

    function getUsers() public view returns(User[] memory){
        return users;
    }

    function addUser(User memory newUser) public{
        users.push(newUser);
    }

}

1. 投票合约

pragma solidity >=0.7.0 <0.9.0;

contract voting{

    string public proposalCode;
    function addProposal(string memory code) public{
        require(bytes(code).length>0,"voting: code can not be empty.");
        proposalCode = code;
    }
}
