Stop Missing Bugs With This Simple Trick!

Most bugs don’t hide in the middle of your app. They hide at the edges. In this video, you’ll learn the exact testing trick that exposes the errors developers never expect: Boundary Value Analysis.

If your app requires passwords to be 8–12 characters, most people test with 10. But real testers? We test 7, 8, 12, and 13—because that’s where the real failures live. These “magic numbers” reveal validation mistakes, off-by-one errors, and hidden logic flaws faster than any other technique.

Using my Dream Achievement App as an example, you’ll discover why adding 9, 10, and then attempting the 11th goal often uncovers the biggest crashes and inconsistencies. This single method can find more bugs in 5 minutes than random testing can in an hour.

If you want to become the tester every development team relies on, this video is your starting point.

Want to know the secret to finding the nastiest bugs? This video explains why effective `software testing` demands a focus on `boundary value analysis` and `limit testing`, not just testing in the middle. We'll show you how proper `input validation` at the edges is crucial for efficient `bug fixing` and building truly resilient software.
