Every time you open an app on your phone or computer, have you ever stopped to wonder why it works so smoothly? It’s not just luck—there’s a dedicated team behind the scenes making sure everything functions perfectly. That’s where Manual QA Engineers come in.

Here’s how it works: Developers create the app, but before it reaches users like you, Manual QA Engineers step in to test every feature. They click buttons, navigate menus, and explore every function—just like a real user would. If they find errors, glitches, or anything that seems off, they report them so developers can fix the issues before the app goes live.

But testing isn’t just about finding bugs. As a Manual QA Engineer, you also help improve the user experience. Should the checkout button be easier to find? Would the app feel more intuitive if a menu was placed differently? You’ll be asking these questions and shaping how users interact with software.

The best part? This is a high-demand job that pays well. Companies are always looking for QA testers because every app, website, or software product needs thorough testing before release. Many companies also offer remote work options, giving you the flexibility to work from home or in a hybrid setup.

Now, if you’re curious about how software works and love the idea of ensuring smooth user experiences, this practical book is the perfect starting point. You'll learn everything from the essential tools and testing processes to career growth strategies.

Packed with a bunch of code samples and hands-on practice exercises, this book allows you to apply what you learn in real-world scenarios, helping you build confidence and technical skills.

By the time you finish reading, you’ll have a clear roadmap to launching your career in Manual and Automated QA Testing—no prior experience needed.

With this book as your guide, you can take the first step toward your new career today!
