Nach dem Ausführen des Trüffeltests erhalte ich die folgende Fehlermeldung:

Wenn keine Ereignisse ausgegeben wurden, was genau schlägt dann fehl?
das ist mein js:
var DappToken = artifacts.require("./xyzToken.sol");
contract('xyzToken', function(accounts) {
var tokenInstance;
it('sets the total supply upon deployment', function() {
return xyzToken.deployed().then(function(instance) {
tokenInstance = instance;
return tokenInstance.totalSupply();
}).then(function(totalSupply) {
assert.equal(totalSupply.toNumber(), 600000000, 'sets the total supply to 600,000,000');
return tokenInstance.balanceOf(accounts[0]);
}).then(function(adminBalance) {
assert.equal(adminBalance.toNumber(), 600000000, 'it allocates the inital supply to the admin account');
});
});
});
und Festigkeit:
pragma solidity ^0.4.23;
contract xyzToken {
uint256 public totalSupply;
mapping(address => uint256) public balanceOf;
function xyzToken (uint256 _initialSupply) public {
balanceOf[msg.sender] = _initialSupply;
totalSupply = _initialSupply;
}
}
Ich habe die Gesamtversorgung für Anzahl und Admin-Guthaben geltend gemacht und Ganache-Konten mit einem assoziativen Array konfiguriert. Was genau ist an meinem Token nicht definiert?
jede Hilfe wäre willkommen
Die oberste Zeile Ihres Javascripts ist falsch. Sie haben das Artefakt aufgerufen, DappTokenaber versucht, es mit zu instanziieren xyzToken, was nicht definiert ist, und daher der Fehler, den Sie erhalten.
Ziehen Sie auch in Betracht, wie folgt zu async/await zu wechseln – es macht die Tests für die Augen viel einfacher:
const DappToken = artifacts.require("./xyzToken.sol");
contract('xyzToken', accounts => {
it('sets the total supply upon deployment', async () => {
const tokenInstance = await DappToken.deployed()
, initSupply = 600000000
, totalSupply = await tokenInstance.totalSupply()
, adminBalance = await tokenInstance.balanceOf(accounts[0])
assert.equal(totalSupply.toNumber(), initSupply, `Total supply should be ${initSupply}!`)
assert.equal(adminBalance.toNumber(), initSupply, 'Initial supply should be allocated to admin account!')
})
})
