QA Web3 - Balance Check

This project demonstrates a simple Web3 test script that connects to an Ethereum-compatible network and retrieves the ETH balance of a wallet address.

📊 Objective

As a QA automation engineer transitioning into Web3, this test validates that:

• The dApp can connect to a provider (e.g. Infura or Alchemy).
• The wallet address is valid.
• The balance is retrieved correctly in Ether (ETH).

🚀 How to Run

1. Clone the repository:

git clone https://github.com/yourusername/qa-web3-balance-check.git
cd qa-web3-balance-check

2. Install dependencies:

npm install

3. Create a .env file with the following content:

RPC_URL=https://mainnet.infura.io/v3/YOUR_PROJECT_ID
WALLET_ADDRESS=0xYourWalletHere

4. Run the script:

node qa-web3-balance-check.js

📊 Sample Output

✅ Wallet balance for 0x1234...abcd: 2.735 ETH

✅ Testing (optional)

You can add a test to assert that the retrieved balance is a valid number and the address format is correct. A sample test will be provided using Jest or Mocha.
