Software Errors Volume Number: 6 Issue Number: 11 Column Tag: Developer's Forum Software Errors: Prevention and Detection By Karl E. Wiegers, Ph.D., Fairport, NY Software Errors: Prevention and Detection Most programmers are rather cavalier about controlling the quality of the software they write. They bang out some code, run it through some fairly obvious ad hoc tests, and if it seems okay, they’re done.

While this approach may work all right for small, personal programs, it doesn’t cut the mustard for professional software development. Modern software engineering practices include considerable effort directed toward software quality assurance and testing.

The idea, of course, is to produce completed software systems that have a high probability of satisfying the customer’s needs. There are two ways to deliver software free of errors. The first is to prevent the introduction of errors in the first place. And the second is to identify the bugs lurking in your code, seek them out, and destroy them. Obviously, the first method is superior. A big part of software quality comes from doing a good job of defining the requirements for the system you’re building and designing a software solution that will satisfy those requirements. Testing concentrates on detecting those errors that creep in despite your best efforts to keep them out. Crash 1996 Uncut Download Movies.

In this article we’ll take a look at why the issue of software quality should be on the tip of your brain whenever you’re programming, as well as discussing some tried-and-true methods for building high-quality software systems. Then we’ll explore the strategies and tactics of software testing. Why Worry About Software Quality? Driver Bluetooth Download Usb.

The computer hobbyist doesn’t think much about software quality. We write some little programs, experiment with graphics tricks, delve into the operating system, and try to learn how the beast works. On occasion we write something useful, but mostly just for own benefit. The “quality” of one-user, short-lived programs like these doesn’t really matter much, since they’re not for public consumption. The professional software engineer developing commercial products or systems for use by his employer has a more serious problem.

Besides the initial effort of writing the program, he has to worry about software maintenance. “Maintenance” is everything that happens to a program after you thought it was done. In the real world, software maintenance is a major issue. Industry estimates indicate that maintenance can consume up to 80 percent of a software organization’s time and energy.

As a great example of the importance of software maintenance, consider how many versions of the Macintosh operating system have existed prior to version 7.0. Each new system version was built upon the previous one, probably by changing some existing code modules, throwing out obsolete modules, and splicing in new ones. The chore of maintenance is greatly facilitated if the software being changed is well-structured, well-documented, and well-behaved. More often, however, code is written rather sloppily and is badly structured.

Over time, such code becomes such a tangle of patches and fixes and kludges that eventually you’re better off re-writing the whole module, rather than trying to fix it once again. High-quality software is designed to survive a lifetime of changes. What is Software Quality? Roger Pressman, a noted software engineering author and consultant, defines software quality like this: Conformance to explicitly stated functional and performance requirements, explicitly documented development standards, and implicit characteristics that are expected of all professionally developed software. A shorter definition is that a high-quality software system is one that’s delivered to the users on time, costs no more than was projected, and, most importantly, works properly.
