Testing helps us find bugs, but it can never prove the software is completely bug-free. It's about uncovering what's wrong, not proving that everything works perfectly. Secondly, exhaustive testing is impossible. It's not practical or even possible to test every single scenario. That's why we focus on the most important areas based on risk and priority. Next up, early testing saves time and money. The earlier you find defects in the development process, the cheaper and easier they are to fix. It's like catching a small leak before it becomes a flood. Fourth, defects cluster together. You'll often find that the majority of bugs are concentrated in a few parts of the…
