Unit Testing

Unit testing is the practice of testing individual components or functions of a smart contract in isolation to ensure they work as expected. By breaking down complex logic into smaller, verifiable units, developers can catch bugs early in the development cycle.

These tests are typically written in the same language as the contract and are executed frequently during the build process. Unit tests provide a baseline for reliability and make it easier to refactor code without introducing new errors.

In financial systems, unit testing is the first line of defense against logic flaws. It is an essential component of modern software development practices.
