ArticlesHigh-Tech Tool for Low-Down Bugs


March 1996 / Applications Development News & Views / High-Tech Tool for Low-Down Bugs
Robert L. Hummel

The complexity of today's large applications seems destined to foil the attempt of even the most thorough development team to ship bug-free software. Seemingly small defects can ripple through a product, branding it with a reputation for being unreliable and bug-ridden. Ultimately, the cost of bugs to the developer and the company can far exceed their original impact.

Automatic testing of release candidates coupled with a large-scale beta-testing program will generally uncover a majority of the most common bugs. But what about those occasio nal bugs that occur only in odd configurations? Can you be sure you've gotten them all?

The cost of fixing bugs at a late stage of product development is high, requiring patches, updates, and technical support. The optimum and most cost-effective time to detect and correct bugs is as they're coded.

Well known for its Soft-ICE family of debugging products, NuMega recently announced a new edition of its BoundsChecker automated error-detection and analysis product for Windows 95 and Windows NT applications. BoundsChecker Professional automatically detects 72 categories of Windows errors -- three times as many as the standard edition detects -- while your program is running. These include dynamic memory overruns, resource leaks, pointer checks, and Windows API function failures. Along with flagging errors, the program provides comprehensive explanations and code examples of the errors, and instructions on how to correct them.According to Jim Moskun, chairman of NuMega, "The ability to 'check early, check often' will accelerate error detection and make it faster and easier to isolate and fix programming errors." NuMega claims that you can cut up to 20 percent of a project's development time by using BoundsChecker Professional to speed debugging.

If you develop applications using Microsoft Visual C++ , you can take advantage of BoundsChecker Professional without departing your integrated development environment (IDE). The program appears on the toolbar, in the pull-down menus, and as a folder tab. BoundsChecker Professional mimics the user interface of Visual C++, allowing you to use it as easily as the standard commands to build, run, and test your programs.

The program also features NuMega's Compile-Time Integration technology, which enhances debugging while leaving your original source code unchanged. At compile time, BoundsChecker Professional automatically inserts error-checking code into your program, saving you hours of editing and recompiling and encouraging frequent bug-checking. To meet the increased demand for software quality assurance, developer s must assume a greater responsibility for thoroughly testing their code. With tools like BoundsChecker Professional, you can do so in a convenient and nonintrusive way.
