SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you validate Solidity smart contracts thoroughly so you can catch logic bugs, edge cases, gas regressions, and integration issues before deployment.

Core Features & Use Cases

  • Unit and Integration Testing: Build reliable test suites for contract behavior, state changes, and event emission.
  • Advanced Validation: Use fuzzing, snapshot and revert flows, gas comparison, and time-based assertions to harden protocol logic.
  • Mainnet Forking and Verification: Recreate real-world DeFi conditions with forked network tests and verify contracts after deployment.
  • Use Case: You are launching a token or DeFi protocol and need confidence that transfers, permissions, and external protocol interactions behave correctly under realistic conditions.

Quick Start

Use this skill to design a complete smart contract test strategy for my Solidity project, including unit tests, integration tests, forked mainnet checks, and verification steps.

Frequently Asked Questions about web3-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test smart contracts for logic bugs and edge cases?▼

Testing smart contracts for logic bugs requires building unit and integration suites with Hardhat and Foundry to validate state changes and event emission, plus applying fuzzing to catch edge cases.

How do I set up mainnet fork testing for DeFi protocol interactions?▼

Mainnet fork testing recreates real-world DeFi conditions by executing tests against a forked network environment, allowing you to validate external protocol interactions and permissions accurately before deployment.

Can I use Foundry fuzzing with Hardhat fixture-based setup?▼

Foundry fuzzing and Hardhat fixture-based setups are supported together to harden protocol logic through randomized inputs, snapshot flows, revert validations, and time-based assertions within your test suites.

What's the best way to check gas optimization regressions in Solidity?▼

Checking gas optimization regressions in Solidity is done through automated gas comparison checks within your test suites, ensuring that code changes do not unexpectedly increase transaction gas costs.

Do I need Etherscan verification steps after testing smart contracts?▼

Etherscan verification is needed after testing smart contracts to confirm deployed contract code on the network, and this workflow is supported alongside coverage reporting and forked network execution.
