Dive into the sixth part of an Ethereum Smart Contract Programming tutorial series, focusing on writing unit tests for a ballot smart contract using Brownie, Python, and Pytest. Learn how to achieve 100% test coverage for the main functionalities of the contract developed in the previous episode. Explore the process of testing Solidity smart contracts with Python, leveraging Brownie's powerful testing framework. Gain insights into best practices for ensuring the reliability and security of your smart contracts through comprehensive unit testing. Build upon the knowledge from earlier parts of the series and prepare for the upcoming episode on deploying the contract to the Rinkeby Network.
