松露測試 - 錯誤：契約尚未部署到檢測到的網路（網路/工件不匹配）

  • November 15, 2021

當我過度閱讀所有給出的文章並且沒有解決我的問題時，我正在打開這個文章。請不要認為每個測試都是有用的，因為我正在開發有用的測試。如前所述，它與*(network/artifact mismatch) 錯誤*有關。

在下面你會找到我的原始碼

./test/TestEscrow.js文件

/* 
 @dev: web3 instance is available in each test
*/

// Contracts that need to be interacted within the test
const TestEscrow = artifacts.require("../contracts/Escrow.sol");

contract("Testing Escrow SC", (accounts) => {
 const importer = accounts[0];
 const exporter = accounts[1];
 const carrier = accounts[2];

 it("ESCROW: Initial escrow contract test", async () => {
   const escrow = await TestEscrow.deployed();
   console.log(escrow); //checking if contract was properly deployed

   const escrowBalance = await escrow.getBalance.call(accounts[0]);
   console.log(escrowBalance);
   const escrowBalanceToNumber = await escrowBalance;
   console.log(escrowBalanceToNumber);
   assert.equal(escrowBalance, 100, "100 was not in the first account");
 });

 it("ESCROW: Constructor test", async () => {
   const escrow = await TestEscrow.deployed();
   console.log(escrow); //checking if contract was properly deployed

   await escrow.new(carrier, exporter, 10, { from: accounts[0] });
   assert.equal(
     escrow.owner,
     importer,
     "The importer is not the contract owner, which is accounts[0]."
   );
   assert.equal(escrow.exporter, exporter, "The exporter is not accounts[1].");
   assert.equal(escrow.carrier, carrier, "The carrier is not accounts[2].");
   assert.equal(
     escrow.value,
     10,
     "THe value of the ESCROW account is not 10."
   );
 });
});

./contracts/Escrow.sol

//SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.10;

contract Escrow{
   
   address payable owner;
   address payable importer; 
   address payable exporter;
   address carrier;
   uint value;
   State state;


   event EscrowCreated(address indexed _importer, address indexed _exporter, address indexed _carrier, uint _value);

   constructor (address payable _carrier, address payable _exporter, uint256 _value) {
       require(_carrier != address(0), "Carrier missing");
       require(_exporter != address(0), "Exporter missing");
       owner = payable(msg.sender); //we assume the impoert is the person calling
       importer = payable(msg.sender);
       carrier = _carrier;
       exporter = _exporter;
       value = _value;
       state = State.waitingForDeposit;
       emit EscrowCreated(msg.sender, _exporter, _carrier, _value);
   }
   
}

./migrations/1_initial_migrations.js

var Migrations = artifacts.require("./Migrations.sol");

module.exports = function (deployer) {
 deployer.deploy(Migrations);
};

./migrations/2_deploy_contracts.js

var Escrow = artifacts.require("../contracts/Escrow.sol");
var Lc = artifacts.require("../contracts/Lc.sol");

module.exports = function (deployer, network, accounts) {
 deployer.then(async () => {
   deployer
     .deploy(Escrow, accounts[1], accounts[2], 10, {
       from: accounts[0],
     })
     .then((inst) => console.log(inst));
   deployer.deploy(Lc);
 });
};

truffle-config.js

const path = require("path");

module.exports = {
 // See <http://truffleframework.com/docs/advanced/configuration>
 // to customize your Truffle configuration!
 // contracts_build_directory: path.join(__dirname, "client/src/contracts"),
 networks: {
   develop: {
     host: "127.0.0.1",
     port: 8545,
     network_id: "*",
   },
   test: {
     host: "127.0.0.1",
     port: 8545,
     network_id: "*",
   },
 },
 compilers: {
   solc: {
     version: "^0.8.0",
     settings: {
       /* 
         Optimizer is able to allocate assigned variables in a more efficient way. For example it adds up multiple uint64 to a whole uint256 block. 
       */
       optimizer: {
         enabled: true,
         runs: 200,
       },
     },
   },
 },
};

所以現在的問題是，如果我正在跑步truffle test或truffle test --network develop. 儘管編譯了合約並部署了初始合約，但因為它返回了EscrowCreated事件（請參閱 參考資料Escrow.sol），它仍然表示兩個測試都失敗了，並且在這兩種情況下都會發出 <(network/artifact mismatch)> 錯誤。請參閱下面的錯誤消息：

希望有人可以向我解釋我的測試與工件不匹配到底發生了什麼。答案越詳細，我會學到的越多。期待你的回复！

親切的問候，安德烈亞斯

#2 已編輯（問題）：分享一個想法：我認為我可能對遷移文件之間的關係有誤（因為我在那裡呼叫了 Escrow 構造的建構子及其參數）並且我認為實際的初始化在定義我的實際測試案例時，契約更有可能發生在測試文件中。期待您能澄清這個額外的問題/想法。

#3 已編輯（附加資訊）：即使我刪除了.build/contracts/目錄中的所有文件，重新執行truffle compile，truffle migrate --reset --network develop錯誤仍然存在。

#4 已編輯（問題）：此外，我觀察到契約 ABI 在其參數中./build/contracts/不包含值。"networks": {}這正常嗎？

你的問題在這裡：

var Escrow = artifacts.require("../contracts/Escrow.sol");
var Lc = artifacts.require("../contracts/Lc.sol");

module.exports = function (deployer, network, accounts) {
 deployer.then(async () =&gt; {
   deployer
     .deploy(Escrow, accounts[1], accounts[2], 10, {
       from: accounts[0],
     })
     .then((inst) =&gt; console.log(inst));
   deployer.deploy(Lc);
 });
};

您正在使用 Promise，但您永遠不會返回它，因此它永遠不會實現並且部署資訊永遠不會更新。

如果您希望保留承諾版本（不推薦），請切換到此版本（稍作修改的版本未部署我沒有的 LC 契約）：

var Escrow = artifacts.require("Escrow");

   module.exports = function (deployer, network, accounts) {
     deployer.then(async () =&gt; {
       return deployer.deploy(Escrow, accounts[1], accounts[2], 10, {from: accounts[0]})
     });
   };

或者您可以簡單地切換到您已經在其他地方使用的 async/await（推薦）：

var Escrow = artifacts.require("Escrow");

module.exports = function (deployer, network, accounts) {
 deployer.then(async () =&gt; {
   await deployer.deploy(Escrow, accounts[1], accounts[2], 10, {from: accounts[0]})
 });
};

您的第一個測試仍然失敗，但您沒有提供完整的實現，所以我只驗證了部署是否成功。

我用這段程式碼測試過：

 it("ESCROW: Initial escrow contract test", async () =&gt; {
   const escrow = await TestEscrow.deployed();
   //const escrowBalance = await escrow.getBalance.call(accounts[0]);
   //const escrowBalanceToNumber = await escrowBalance;
   //assert.equal(escrowBalance, 100, "100 was not in the first account");
 });

鑑於您目前的契約程式碼，您的第二個測試將不起作用：

address payable owner;
address payable importer; 
address payable exporter;
address carrier;
uint value;
State state;

預設可見性internal因此無法從外部訪問。在需要時簡單地指定 public 將允許外部訪問您的公共變數（假設它們都需要是公共的）：

address payable public owner;
address payable public importer; 
address payable public exporter;
address public carrier;
uint public value;
State public state;

然後將第二個測試的程式碼更改為：

 it("ESCROW: Constructor test", async () =&gt; {

   const escrow = await TestEscrow.new(carrier, exporter, 10, { from: accounts[0] });

   assert.equal(
     await escrow.owner(),
     importer,
     "The importer is not the contract owner, which is accounts[0]."
   );
   assert.equal(await escrow.exporter(), exporter, "The exporter is not accounts[1].");
   assert.equal(await escrow.carrier(), carrier, "The carrier is not accounts[2].");
   assert.equal(
     await escrow.value(),
     10,
     "THe value of the ESCROW account is not 10."
   );
 });

利用自動生成的“getter”，您可以讀取公共變數的狀態。

在這些更改之後，我這邊一切正常。
