If a tester is "somebody who knows that things can be different," then Marshall McLuhan was a tester par excellence. According to McLuhan, the English professor who proposed the Laws of Media, the message of a medium is not its content but rather its effects. Find out how this translates to software testing and how we evaluate requirements.

One of the testing challenges we face is how to handle the large numbers of test cases we sometimes need to create and execute. We can't test everything, but pairwise testing using orthogonal arrays or an all-pairs algorithm can help generate pair combinations that reduce the number of test cases we run while still finding a large percentage of bugs.

When the design and the coding are complete, and the product seems ready to ship, it’s hard to understand why testing takes so long. Discover how your source code management system can help you unblock the testing bottleneck.

There are no industry standards for Web response times. How long a user is willing to wait for a Web page to load depends on any number of variables and conditions. Find out how to determine and quantify performance criteria and use those criteria to create happy customers.
