Unit and Integration Testing Strategies — Forge College

Why differentiate unit and integration tests? Clear test scope and isolation are the difference between flaky CI and deterministic, fast feedback loops for smart contracts.

What you'll learn
You will learn practical techniques to design both unit and integration tests using Foundry and the foundry-testing-suite. The lesson shows how to isolate a single FeeCalculator function for deterministic assertions and how to compose a Vault + Token integration test to validate end-to-end flows. You'll see how to use local mocks and stubs, test lifecycle hooks, and fixtures to keep tests fast and repeatable. The lesson also covers selecting the right Foundry workflow scope (unit vs integration), using forge test flags, and writing assertions and failure traces that remain stable across CI environments.

Who this is for
This lesson is aimed at intermediate Solidity developers who already know basic Foundry test lifecycle hooks, test folder layout, and simple assertions. Prior experience running forge test is helpful but not required.

Key topics covered
- Criteria that distinguish unit tests from integration tests in Solidity
- Isolating behavior for deterministic assertions with mocks and stubs
- Building a FeeCalculator unit test using the foundry-testing-suite
- Composing a Vault + Token integration test to validate end-to-end logic
- Choosing Foundry workflow scopes and using forge flags for targeted runs
- Test lifecycle hooks, local fixtures, and CI-friendly assertions
