COVER STORY
• Testing Complex Systems
  By Gigi Sayfan
When dealing with complex systems, you have to design testability from the get go or refactor toward it. The good news is that good design (modular and loosely coupled elements with well defined responsibilities and interfaces between modules) leads to systems that are more testable, scalable, performant, and secure.


• Testing Browser Apps
  By Andy Sylvester
The QUnit framework makes it easy to test Web apps directly in the browser. By showing the red/green results in the browser with links to the failing tests, it makes it possible to write, test, and correct quickly.

GUEST EDITORIAL

Tired of grinding out unit tests by hand? Worried that you've missed a set of values to test for? Dino Esposito suggests that Microsoft's little-known Pex could be your solution.

FROM THE VAULT
• Perl Testing
  By Peter Scott
Perl supports enough testing mechanisms to facilitate applications with hundreds of thousands of lines of code, multiple developers, enterprise-level, mission critical, and so on. In typical Perl community style, there are so many testing modules available that you can find something to support just about any preference, no matter how idiosyncratic.
