What Is Failure-Directed Testing?

Fail fast, fail often. The idea that a software program can be tested with the same level of thoroughness as a human is pretty ridiculous. It's like expecting your computer to solve world hunger. Sure, it might be able to do it in theory, but it's not going to happen in practice! and even if we did have the technology to create a computer that could do everything a human can do. There are still some things that computers aren't built for. They don't have intuition or common sense—they don't know what's essential and what isn't, so they're not going to be able to tell the difference between what matters and what doesn't. That's why failure-directed testing is so important: it allows you to focus on the most likely errors for a software or program while still getting the complete picture of how well it works. It tries to work more intelligently than a blanket or standard testing because it knows precisely what you should expect from this type of product or program and how those expectations might differ from other kinds of programs or products (or humans). If you're a tester and you've had to test a piece of code that was nothing but a black box, then you know how frustrating it can be. Black-box testing is when the person who runs your tests doesn't have access to the source code—they just run the program with no idea what's going on under the hood. Sure, it's great for ensuring that your program works in its current state, but it's not so great at catching bugs in specific areas of your code base. But don't worry! There's an easy way around this problem: failure-directed testing! Failure-directed testing focuses on areas where failure is more likely to happen. You do this by analyzing which parts of your code have more complex or nebulous data and running tests specifically focused on those areas. So next time someone asks you why they should care about failure-directed testing? Tell them it'll help them save precious time by focusing their efforts where they're most likely to find bugs!
