How programmers test

Have you ever wondered how developers ensure their applications run smoothly? Welcome to the fascinating world of software testing! In this lesson, we'll dive into what software testing is and why it's a crucial part of the programming process. Software testing is the process of evaluating and verifying that a software application meets the required standards and works as intended. Think of it as a safety net that catches bugs before they reach the users. For instance, consider an online shopping website. If a user tries to add an item to their cart and it fails, that’s a critical bug that needs fixing. By testing the functionality of the 'add to cart' feature, programmers can ensure that customers have a seamless experience.

In this lesson, we'll explore different types of testing, including unit testing, integration testing, and system testing. Each type serves a unique purpose in the development lifecycle, helping to identify issues at various stages. We'll also discuss how testing can save time and resources in the long run by preventing major problems from surfacing post-launch.

1. Define software testing in your own words.
2. List at least three reasons why software testing is important.
3. Identify a software application you use regularly and think of one potential bug that could occur.
