Blockchain Testing

Purpose

Guide blockchain smart contract testing covering the full testing pyramid: unit tests, integration tests, fuzz tests, invariant tests, formal verification, and audit preparation. Ensures contract correctness before deployment.

Input Context

• Smart contracts to test (with source files)
• Framework preference (Foundry/Hardhat/Truffle)
• Testing phase (unit/fuzz/invariant/formal/audit)
• Existing test suite and coverage
• Target chains (EVM/Solana/Cosmos)
• Security requirements (audit timeline, TVL at risk)
