Transform Your Software

Bring out the best in your code. Systematic code transformations are an important tool for test-driven development. Refactoring and generalization—common code transformations in TDD—improve the code while preserving its behavior and broaden the capabilities of the software. Each technique has its place, and together they help make TDD effective.

What's on Your Dashboard?

Just because a metric is easy to capture doesn't mean it is useful. The metrics that are really needed are the ones that can help you make good decisions. Find out how to establish a project dashboard with meaningful metrics that will guide your project safely to its destination without getting bogged down in an endless pursuit of unnecessary information.

Pairwise Testing: An Easy Guide to Orthogonal Arrays & All-Pairs Combinations

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.

The Secret to Software Development

In the wake of Rhonda Byrne's bestseller The Secret, Carol Dekkers examines whether the theories behind Byrne's blockbuster can be applied to software development. Can the Law of Attraction and positive energy really be all it takes for successful, positive project results—or is that just wishful thinking?

The Lecture

Whether you're being admonished for having more than ten items in the express lane at the supermarket or you are telling off a tester for missing a bug, at some point we've all been on the giving and on the receiving end of The Lecture. We're all human and fallible. Isn't there a more effective (and mature) way to communicate when a problem arises?

Navigating the Installation

If you've ever popped a CD into a drive and run an install for software you're about to test, then you might be performing installation testing indirectly. If not properly installed, an application could give false results for all other testing. A better strategy is to test the install process directly, which will give you greater confidence in the quality of your software.

Ready, Aim, Release

Think you know what your customer wants? Can you afford to be wrong? Based on the concept of tracer ammunition, which allows a shooter to follow the path of a bullet toward its target and adjust his aim as needed, tracer bullet software development can help you better understand your users’ wants so you can build a product that hits the mark.

Skills for Software Smokejumpers

Sometimes the only way to get a fire under control is to call in the smokejumpers. These specially trained firefighters parachute into a region to take on a blaze and contain it before any more damage is done. Some software development projects have smokejumpers, too. These professionals enter struggling projects midstream, assess the situation, and hopefully lead the team to a successful outcome.

Users We Don't Like

Mom always said, "If you can't say something nice, don't say anything at all." But Michael Bolton made an interesting discovery when he asked testers to talk about users they don't like. While nobody likes a complainer, listening to what your users are saying--even if you don't like it--can help you spot problems you may have overlooked.
