Solidity智能合约开发测试环境搭建

以太坊合约开发工具非常多，但是功能上各有优缺点，因此如何选择搭配一套比较好用的开发和测试环境就非常重要。我在开发实践中摸索发现了一种方便快捷的开发和测试方法。

总结下来就是：

1、使用https://ethfiddle.com/进行代码开发，调试

2、使用testrpc和geth做发布前功能测试

3、使用metamask进行发布

1、使用https://ethfiddle.com/进行代码开发，调试

打开网站https://ethfiddle.com/，这个工具使用非常简单，只需要在左边的编辑框内输入代码，下面的error就会同步编译并展示错误信息，代码编辑完成后，直接点击右边的deploy就可以发布合约，合约发布后，右边框内可以出现合约可以调用的函数，

点击call就可以调用合约对应的代码

注意：如果函数名称为空，我们可以先写个名字用来调试，发布的时候去除这个名称就可以了；同理对private的函数也可以先设置为public来调试

2、使用testrpc和geth做发布前功能测试

本文在windows开发环境下，当然其他环境也验证了可以成功

我们需要安装testrpc和geth

A、安装testrpc

npm install -g ethereumjs-testrpc

运行testrpc后显示版本信息：EthereumJS TestRPC v6.0.3 (ganache-core: 2.0.2)

B、geth 下载：

https://geth.ethereum.org/downloads/

运行geth version后显示版本信息

Version: 1.8.1-stable

Git Commit: 1e67410e88d2685bc54611a7c9f75c327b553ccc

C、在cmd窗口启动testrpc

直接testrpc回车

D、在另外一个cmd窗口启动geth

输入：geth attach http://127.0.0.1:8545

E、在geth控制台创建帐号并转账

转账测试：

eth.accounts
personal.newAccount("123456")
eth.getBalance(eth.accounts[0])
eth.coinbase
eth.getBalance(eth.accounts[10])
eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[10],value:web3.toWei(5,'ether')})

F、合约发布

https://ethfiddle.com/ 网站没有给我们生成web3脚本，我们这里使用remix来自动生成脚本

打开http://remix.ethereum.org，新增文件Token.sol，内容如下：

pragma solidity ^0.4.18;
contract Token {
    address issuer;
    mapping (address => uint) balances;
    event Issue(address account, uint amount);
    event Transfer(address from, address to, uint amount);
    function Token() public payable{
        issuer = msg.sender;
    }
    function issue(address account, uint amount) public {
        assert(msg.sender == issuer);
        balances[account] += amount;
    }
    function transfer(address to, uint amount) public {
        assert (balances[msg.sender] >= amount);
        balances[msg.sender] -= amount;
        balances[to] += amount;
        Transfer(msg.sender, to, amount);
    }
    function getBalance(address account) public constant returns (uint) {
        return balances[account];
    }
}

选择右边的编译，然后点击detail，选择WEB3DEPLOY，点击复制，把下面的内容放入geth console中

var tokenContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"account","type":"address"},{"name":"amount","type":"uint256"}],"name":"issue","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"to","type":"address"},{"name":"amount","type":"uint256"}],"name":"transfer","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"account","type":"address"}],"name":"getBalance","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":false,"name":"account","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Issue","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"from","type":"address"},{"indexed":false,"name":"to","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Transfer","type":"event"}]);
var token = tokenContract.new(
   {
     from: web3.eth.accounts[0],
     data: '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',
     gas: '4700000'
   }, function (e, contract){
    console.log(e, contract);
    if (typeof contract.address !== 'undefined') {
         console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
    }
 })

成功编译，显示：

Contract mined! address: 0xd481dea9b8e8399c263e7e77bb09d9e617da2a92 transactionH

ash: 0xec04e48ed031122d5fc57481aefa55c9bc79cd863ce6f364eec79e47d3608d0e

注意：上面是两行web3代码，我们分别复制到geth控制台，然后回车，否则可能看不到Contract mined! Address这些信息

G、合约测试

在geth控制台，测试充值：

token.issue(eth.accounts[0], 100, {from: eth.accounts[0]});

查看余额：

token.getBalance(eth.accounts[0])

转账：

token.transfer(eth.accounts[1], 30, {from: eth.accounts[0]})

查看余额：

token.getBalance(eth.accounts[0])
token.getBalance(eth.accounts[1])

3、使用metamask进行发布

这个参考http://liyuechun.org/2017/09/03/solidity-MetaMask/ ，使用remix和metamask搭配，在metamask里面选择main network就可以发布了，只是前提是要去买点eth。
