【问题描述】：
当我在终端上运行 truffle test 时，我收到以下错误 Error: Attempting to run transaction which calls a contract function, but recipient address 0x3ad2c00512808bd7fafa6dce844a583621f3df87 is not a contract address 我不明白为什么会这样，因为我的 build 文件夹是正常含义，如果我运行 truffle migrate --reset 终端中的地址是与构建文件中的地址相同。当我运行 truffle migrate 时，它可以工作。此外，每次我运行松露测试时，收件人地址总是会发生变化。不知道有什么可以帮忙的。
另一件事只有在我使用代码selfdestruct(admin); 时才会发生，然后我会收到此错误。管理员是 = msg.sender，这是 ganache 中的第一个帐户，所以我不知道出了什么问题。
我正在使用this 视频。我已经完成了这个人的所有其他视频，一切都很好，直到现在 15:11 分钟，他进行了最终测试，对他来说，它有效，但对我来说，它给了我上面的错误。
请大家帮忙
这是我的测试（javascript）
var CinoCoin = artifacts.require("./CinoCoin.sol");
var CinoCoinSale = artifacts.require("./CinoCoinSale.sol");
contract('CinoCoinSale', function(accounts) {
var tokenInstance;
var tokenSaleInstance;
var admin = accounts[0];
var buyer = accounts[1];
var tokenPrice = 1000000000000000; // in wei 0.01 ether
var tokensAvailable = 750000;
var numberOfTokens;
it('initializes the contract with the correct values', function() {
return CinoCoinSale.deployed().then(function(instance) {
tokenSaleInstance = instance;
return tokenSaleInstance.address
}).then(function(address) {
assert.notEqual(address, 0x0, 'has contract address');
return tokenSaleInstance.tokenContract();
}).then(function(address) {
assert.notEqual(address, 0x0, 'has token contract address');
return tokenSaleInstance.tokenPrice();
}).then(function(price) {
assert.equal(price, tokenPrice, 'token price is correct');
});
});
it('facilitats token buying', function() {
return CinoCoin.deployed().then(function(instance) {
//Grab token instance first
tokenInstance = instance;
return CinoCoinSale.deployed();
}).then(function(instance) {
//Then grab token sale instance
tokenSaleInstance = instance;
//Provision 75% of all tokens to the token sale contract
return tokenInstance.transfer(tokenSaleInstance.address, tokensAvailable, { from: admin})
}).then(function(receipt) {
numberOfTokens = 10;
return tokenSaleInstance.buyTokens(numberOfTokens, { from: buyer, value: numberOfTokens * tokenPrice })
}).then(function(receipt) {
assert.equal(receipt.logs.length, 1, 'triggers one event');
assert.equal(receipt.logs[0].event, 'Sell', 'should be the "Sell" event');
assert.equal(receipt.logs[0].args._buyer, buyer, 'logs the account that purchased the tokens');
assert.equal(receipt.logs[0].args._amount, numberOfTokens, 'logs the number of tokens purchased');
return tokenSaleInstance.tokensSold();
}).then(function(amount) {
assert.equal(amount.toNumber(), numberOfTokens, 'increments the number of tokens sold');
return tokenInstance.balanceOf(buyer);
}).then(function(balance) {
assert.equal(balance.toNumber(), numberOfTokens);
return tokenInstance.balanceOf(tokenSaleInstance.address);
}).then(function(balance) {
assert.equal(balance.toNumber(), tokensAvailable - numberOfTokens);
//Try to buy tokens different from the ether value
return tokenSaleInstance.buyTokens(numberOfTokens, { from: buyer, value: 1 });
}).then(assert.fail).catch(function(error) {
assert(error.message.indexOf('revert') >= 0, 'msg.value must equal number of tokens in wei');
return tokenSaleInstance.buyTokens(800000, { from: buyer, value: numberOfTokens * tokenPrice });
}).then(assert.fail).catch(function(error) {
assert(error.message.indexOf('revert') >= 0, 'connot purchase more tokens than available');
});
});
it('ends token sale', function () {
return CinoCoin.deployed().then(function(instance) {
//Grab token instance first
tokenInstance = instance;
return CinoCoinSale.deployed();
}).then(function(instance) {
//Then grab token sale instance
tokenSaleInstance = instance;
//try to end sale from account other than admin
return tokenSaleInstance.endSale({ from: buyer });
}).then(assert.fail).catch(function(error) {
assert(error.message.indexOf('revert' >= 0, 'must be admin to end sale'));
//End sale as admin
return tokenSaleInstance.endSale({ from: admin });
}).then(function(receipt) {
return tokenInstance.balanceOf(admin);
}).then(function(balance) {
assert.equal(balance.toNumber(), 999990, 'returns all unsold cino coins to admin');
//Check that the token price was reset when selfFestruct was called
return tokenSaleInstance.tokenPrice();
}).then(function(price) {
assert.equal(price.toNumber(), 0, 'token price was reset');
});
});
});
这是我的合约代码（solidity）
pragma solidity ^0.4.23;
import "./CinoCoin.sol";
contract CinoCoinSale {
address admin;
CinoCoin public tokenContract;
uint256 public tokenPrice;
uint256 public tokensSold;
event Sell(address _buyer, uint256 _amount);
function CinoCoinSale(CinoCoin _tokenContract, uint256 _tokenPrice) public {
//Assign an admin / an external account connected to the blockchain that has certain priviliges
admin = msg.sender;
//Assign token contract
tokenContract = _tokenContract;
//Token Price how much the token will cost
tokenPrice = _tokenPrice;
}
//multiply function for
function multiply(uint x, uint y) internal pure returns (uint z) {
require(y == 0 || (z = x * y) / y == x);
}
//Buy tokens
function buyTokens(uint256 _numberOfTokens) public payable {
//Require that the value is equal to tokens
require(msg.value == multiply(_numberOfTokens, tokenPrice));
//Require that there are enough tokens in the contrat
require(tokenContract.balanceOf(this) >= _numberOfTokens);
//Require the transfer is successful
require(tokenContract.transfer(msg.sender, _numberOfTokens));
//Keep track of number of tokens sold
tokensSold += _numberOfTokens;
//Trigger a sell event
Sell(msg.sender, _numberOfTokens);
}
//ending token CinoCoinSale
function endSale()public {
//Only an admin can end the end the sale
require(msg.sender == admin);
//Transfer the amount of token in the sale back to the admin
require(tokenContract.transfer(admin, tokenContract.balanceOf(this)));
//Destroy contract
selfdestruct(admin);
}
}
当我注释掉 selfdestruct(admin); 时，它说我的测试通过了，所以这似乎是一个问题
感谢您的帮助
【问题讨论】：
-
显示您的测试。
-
像我所有的代码这样的测试是什么意思？或者我的终端说什么？
-
我添加了用 javascript 编写的测试和我的可靠合同，我希望这会有所帮助
-
我修复了它，这是自毁代码的错误，感谢您的帮助，我很高兴我修复了它
