After finishing the ICO Smart contract. We need deploy and test it.

Truffle support we define the scenario of the deployment in .js file in migrations directory.

Writing the script

We start writing the delopy script. Open your IDE, create/update 2_deploy.contracts.js in migrations directory and copy source code as the below:

const IcoToken = artifacts.require('IcoToken');
const IcoContract = artifacts.require('IcoContract');

module.exports = function(deployer) {
  deployer.deploy(
    IcoToken,
    'Test Token',
    'TST',
    '18',
    '1.0'
  ).then(() => {
    return deployer.deploy(
      IcoContract,
      '0xc3d2a1629d3990d8b9d9799c8675ec18c6f00247', // Your ETH Address
      IcoToken.address,
      '100000000000000000000000000', // 100000000 Token
      '1000', // 1 ETH = 1000 Token
      '1504051200', // 30/08/2017
      '1514592000', // 30/12/2017
      '100000000000000000' // 0.1 ETH
    ).then(() => {
      return IcoToken.deployed().then(function(instance) {
        return instance.setIcoContract(IcoContract.address);
      });
    });
  });
};

Note: you should change parameter Your ETH Address, and endtime ('1514592000', // 30/12/2017)

Deploy the contracts

After that, return root directory and run the deploy command from the terminal

truffle deploy --reset

If success, the output should be:

$ truffle deploy --reset

In the output above, we see the addresses of the contracts:

• IcoToken Address: 0xb598a4a58dc9ae01e75b215f7028db2a926d21e4 => this is your ERC20 Token address
• IcoContract Address: 0x781f0faf06b17ea69cb2aa2bbc9c4942ae4ab398 => this is your token sale contract address. Invertors will send ETH to this address to get the ICO Tokens

Note: please save the addresses above to use for the next steps
