I have the following sol file "Token.sol"

pragma solidity ^0.4.2; contract Token { /// @return total amount of tokens function totalSupply() constant returns (uint256 supply) {} /// @param _owner The address from which the balance will be retrieved /// @return The balance function balanceOf(address _owner) constant returns (uint256 balance) {} /// @notice send `_value` token to `_to` from `msg.sender` /// @param _to The address of the recipient /// @param _value The amount of token to be transferred /// @return Whether the transfer was successful or not function transfer(address _to, uint256 _value) returns (bool success) {} /// @notice send `_value` token to `_to` from `_from` on the condition it is approved by `_from` /// @param _from The address of the sender /// @param _to The address of the recipient /// @param _value The amount of token to be transferred /// @return Whether the transfer was successful or not function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {} /// @notice `msg.sender` approves `_addr` to spend `_value` tokens /// @param _spender The address of the account able to transfer the tokens /// @param _value The amount of wei to be approved for transfer /// @return Whether the approval was successful or not function approve(address _spender, uint256 _value) returns (bool success) {} /// @param _owner The address of the account owning tokens /// @param _spender The address of the account able to transfer the tokens /// @return Amount of remaining tokens allowed to spent function allowance(address _owner, address _spender) constant returns (uint256 remaining) {} event Transfer(address indexed _from, address indexed _to, uint256 _value); event Approval(address indexed _owner, address indexed _spender, uint256 _value);} contract StandardToken is Token { function transfer(address _to, uint256 _value) returns (bool success) { //Default assumes totalSupply can't be over max (2^256 - 1). //If your token leaves out totalSupply and can issue more tokens as time goes on, you need to check if it doesn't wrap. //Replace the if with this one instead. //if (balances[msg.sender] >= _value && balances[_to] + _value > balances[_to]) { if (balances[msg.sender] >= _value && _value > 0) { balances[msg.sender] -= _value; balances[_to] += _value; Transfer(msg.sender, _to, _value); return true; } else { return false; } } function transferFrom(address _from, address _to, uint256 _value) returns (bool success) { //same as above. Replace this line with the following if you want to protect against wrapping uints. //if (balances[_from] >= _value && allowed[_from][msg.sender] >= _value && balances[_to] + _value > balances[_to]) { if (balances[_from] >= _value && allowed[_from][msg.sender] >= _value && _value > 0) { balances[_to] += _value; balances[_from] -= _value; allowed[_from][msg.sender] -= _value; Transfer(_from, _to, _value); return true; } else { return false; } } function balanceOf(address _owner) constant returns (uint256 balance) { return balances[_owner]; } function approve(address _spender, uint256 _value) returns (bool success) { allowed[msg.sender][_spender] = _value; Approval(msg.sender, _spender, _value); return true; } function allowance(address _owner, address _spender) constant returns (uint256 remaining) { return allowed[_owner][_spender]; } mapping (address => uint256) balances; mapping (address => mapping (address => uint256)) allowed; uint256 public totalSupply;} contract HumanStandardToken is StandardToken { function () { //if ether is sent to this address, send it back. throw; } /* Public variables of the token */ /* NOTE: The following variables are OPTIONAL vanities. One does not have to include them. They allow one to customise the token contract & in no way influences the core functionality. Some wallets/interfaces might not even bother to look at this information. */ string public name; //fancy name: eg Simon Bucks uint8 public decimals; //How many decimals to show. ie. There could 1000 base units with 3 decimals. Meaning 0.980 SBX = 980 base units. It's like comparing 1 wei to 1 ether. string public symbol; //An identifier: eg SBX string public version = 'H0.1'; //human 0.1 standard. Just an arbitrary versioning scheme. function HumanStandardToken( uint256 _initialAmount, string _tokenName, uint8 _decimalUnits, string _tokenSymbol ) { balances[msg.sender] = _initialAmount; // Give the creator all initial tokens totalSupply = _initialAmount; // Update total supply name = _tokenName; // Set the name for display purposes decimals = _decimalUnits; // Amount of decimals for display purposes symbol = _tokenSymbol; // Set the symbol for display purposes } /* Approves and then calls the receiving contract */ function approveAndCall(address _spender, uint256 _value, bytes _extraData) returns (bool success) { allowed[msg.sender][_spender] = _value; Approval(msg.sender, _spender, _value); //call the receiveApproval function on the contract you want to be notified. This crafts the function signature manually so one doesn't have to include a contract in here just for this. //receiveApproval(address _from, uint256 _value, address _tokenContract, bytes _extraData) //it is assumed that when does this that the call *should* succeed, otherwise one would use vanilla approve instead. if(!_spender.call(bytes4(bytes32(sha3("receiveApproval(address,uint256,address,bytes)"))), msg.sender, _value, this, _extraData)) { throw; } return true; }} 

which truffle splits into 3 .sol files. The contract HumanStandardToken has an initializer function but can't figure out how to trigger the code in the deploy_contracts.js file.

I'm doing the following

var Coin = artifacts.require("Token") module.exports = function(deployer) { deployer.deploy(Coin, '800000000000000000000000000', 'CoinName', 18, 'MDC',{gas: 4700000}) }; 

But the test do not pass when I check for totalSupply().

pragma solidity ^0.4.2; import "truffle/Assert.sol"; import "../contracts/Token.sol"; contract TestToken { function testTotalSupplyOfCoin() { Token meta = new Token(); uint expected = 8000000000000; Assert.equal(meta.totalSupply(), expected, "Owner should have 8000000000000 Coins initially"); } } 

Error: Owner should have 8000000000000 MetaCoin initially (Tested: 0, Against: 8000000000000)

Edit: I have to add that when I use the console it works as expected

Web3 = require('web3') web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545")); code = fs.readFileSync('contracts/Token.sol').toString() contract = web3.eth.compile.solidity(code) CoinContract = web3.eth.contract(contract.info.abiDefinition) deployedContract = CoinContract.new('800000000000000000000000000', 'CoinName', 18, 'MDC',{data: contract.code, from: web3.eth.accounts[0], gas: 4700000})}) contractInstance = CoinContract.at(deployedContract.address) contractInstance.totalSupply() { [String: '8e+26'] s: 1, e: 26, c: [ 8000000000000 ] } 
0

Try to change the deploy script as follows

var HumanStandardToken = artifacts.require("HumanStandardToken") module.exports = function(deployer) { deployer.deploy(HumanStandardToken, '800000000000000000000000000', 'CoinName', 18, 'MDC',{gas: 4700000}) }; 

This way you're deploying the HumanStandardToken rather than the abstract base class.
