Automated testing is essential in large projects as it consistently checks that code changes don't break existing functionality, which is key to maintaining a stable application. Automated tests run faster and more reliably than manual tests, allowing teams to focus on development rather than repetitive testing tasks. In a large e-commerce project, automated tests can quickly verify that new features like promotions or discount codes don't disrupt the checkout process.
