FAQPage Schema

How do I write Foundry tests for Solidity smart contracts?▼

Generate Foundry fuzz tests for Solidity smart contracts by using this Skill to scaffold test skeletons in the tests/ directory, reducing boilerplate for property-based testing.

How do I generate deployment scripts for Ethereum smart contracts?▼

Generate deployment scripts for Ethereum smart contracts by using this Skill to produce reproducible Foundry deployment script templates within the scripts/ directory.

What is the best way to structure invariant and fork tests in Foundry?▼

The best way to structure invariant and fork tests in Foundry is to use standard Solidity test patterns generated by this Skill, which scaffolds reusable test skeletons for complex scenarios.

Do I need standard Solidity test patterns to use the web3-foundry skill?▼

Yes, you need standard Solidity test patterns and Foundry tooling installed, as the Skill requires these to produce test skeletons, cheat sheets, and deployment scripts correctly.

Can I scaffold integration tests and deployment scripts together for a smart contract ecosystem?▼

You can scaffold integration tests and deployment scripts together by using this Skill to generate templates across both tests/ and scripts/ directories, ensuring reliable tests and reproducible deployments.
