When Robert Sabourin set up a testing lab for a major e-commerce Web-based application, he chose eValid from Software Research, Inc., as the tool for use in functional, performance, and load testing of the application. The product did the job at a very reasonable price, and they were able to find some very important bugs well ahead of their target delivery dates.

Testing, in its broadest sense, means ensuring that your visionaries and programmers are creating a helpful product that people will actually use. As the two authors of this installment of Bug Report illustrate, understanding how those users will operate your application is more than an exercise in empathy; it's a simple key to avoiding some real usability meltdowns.

Errors start with individuals, and a primary job of testers/QA people is to prevent those errors in the first place. But an equally important part of the job is to find them once they are there, understanding that errors will happen. Jon Hagar asks, "What can we do personally, above and beyond the normal day-to-day jobs that we testers and developers have?"

STORM is a software-driven combination of hardware and software that recreates multiple, real-life, WAN links in terms of bandwidth limitations, packet loss, latency, jitter, and more–all in a local area network (LAN) lab. By providing a test bed that brings the WAN into a controlled and repeatable LAN environment, we can test and evaluate the performance and robustness of IP applications or devices before wide-scale deployment, or compare new technologies before field testing.
