web3-testing

To write unit tests for Solidity smart contracts, you can use this framework to set up a Hardhat project and implement robust unit and integration tests using both Hardhat and Foundry environments.

Mainnet forking creates a realistic testing environment by copying mainnet state. It supports advanced patterns like snapshotting and account impersonation to thoroughly validate DeFi protocols and complex contract interactions.

Yes, you can analyze smart contract gas optimization during testing. The framework evaluates contract performance and cost-efficiency, allowing you to identify and resolve gas-heavy operations before testnet deployment.

Web3 testing supports fuzzing for Solidity contracts. It provides comprehensive testing capabilities that include fuzzing alongside unit tests, integration tests, and gas optimization analysis to ensure contract reliability.

You can integrate smart contract testing into CI/CD pipelines for automated quality assurance. The framework connects your Hardhat and Foundry test suites directly to automated pipelines, ensuring continuous validation.

The best way to test ERC20 token transfer logic and access controls is using comprehensive unit and integration tests. This framework validates transfer mechanisms, permissions, and gas usage before mainnet deployment.
