Use of Test Test Accounts: A guide for beginners
As a developer, it is essential to carefully test their intelligent contracts and applications before deploying them on the main network. One of the most effective ways to proceed is to use test accounts on time tests. In this article, we will address how to configure test accounts in Ropsten, one of the most popular time tests for the development of Ethereum.
Why test the accounts on testnets?
Test accounts allow us to simulate real -world transactions and interactions with their smart contracts without risking money or displaying their maintenance keys. This is particularly important when testing the complex logic of intelligent contracts or interaction with external services.
Configuration of a Ropsten Test Account
To create a Ropsten test account, you will need to use the truffle suite. Here is a step by step guide:
- Create a new test account : You can do it by running the following command at your terminal:
`Bash
Truffles Init -T Ropsten
'
This will configure a new test account with an initial balance of 100 ether.
- Set the test network test : Update theconfig.json
file to include the Ropsten Testnet URL, such as http: // ropsten.infura.io / v3 / your_project_id.
Json
{
"network": {
"Name": "Ropsten",
"rpcurl": "
},
// other settings ...
}
'
Replaceyour_project_idid 'with your real infura project id.
Use of test accounts to interact with your contract
After creating a test account, you can use it to interact with your smart contract. Here is an example of how to call the "transfer" function:
JavaScript
Consta {ether} = requires ('truffles');
// Get your contract address and ABI
CONSCEDDRESS = '0xyourcotractaddress';
Consta Abbi = [...]; // Replace with your ABI contract
// Create a new test account
Ethers.wallet.create ({
From: '0xyourtaccount',
Network: "Ropsten"
})
.Then (account => {
console.log ("Ropsten connected");
});
// Call the transfer function
Contacterdress.Transfer (Account.Address, {VALUE: ETHERS.UTILS.PARETHER ('1')});
'
In this example, we created a new test account usingEther.wallet.create`. Then we call the “transfer” function in our contract, transmitting the account address and the amount of the ether to be sent.
Best Practices
Here are some recommended practices to be remembered when using test accounts:
* Use separate portfolios
: Create a new portfolio for each test account to avoid conflict.
* Keep your test accounts safe
: Do not share your private keys or do not connect identification information to anyone.
* Test regularly : Test regularly your smart contract to ensure that they work as planned.
By following these steps, you can create effective Ropsten test accounts to carefully test your intelligent contracts and applications before deploying them on the main network. Do not forget to always follow the recommended practices when using test accounts to maintain your safety and integrity intact.
