*I mean beginner programmers

As a coding newbie, you’ve surely encountered tests. Online coding programs like Codecademy and FreeCodeCamp rely on tests to check users’ input against expected outcomes. There’s nothing more satisfying than having someone (or something) else verify that your code is working correctly. Tests are awesome! They provide feedback and help guide our progress toward an eventual goal. Unfortunately, the real world doesn’t come pre-equipped with tests.
