Advanced Testing with Foundry/Hardhat

Welcome to advanced smart contract testing! As contracts grow in complexity, simple unit tests aren't enough to guarantee robustness.

We need powerful strategies to catch subtle bugs and ensure security. This lesson dives into sophisticated techniques using frameworks like Foundry or Hardhat.

Basic tests check expected behavior, but what about unexpected inputs or complex interactions? Advanced testing helps with:

• Edge Cases: Fuzz testing helps find inputs you didn't anticipate.
• Interactions: Integration tests verify how multiple contracts work together.
• Security: Advanced methods uncover vulnerabilities before deployment.

These are crucial for building battle-hardened smart contracts.
