web3-testing
Comprehensive smart contract testing with Hardhat and Foundry, supporting unit tests, integration tests, mainnet forking, and gas optimization.
- Supports both Hardhat (JavaScript/TypeScript) and Foundry (Solidity) testing frameworks with fixtures, cheatcodes, and assertion libraries
- Includes mainnet forking capabilities for realistic testing against live contract state, account impersonation, and time manipulation
- Covers gas optimization testing, fuzzing for edge cases, snapshot/revert patterns, and automated coverage reporting
- Provides Etherscan contract verification and CI/CD integration examples for automated test pipelines
