Virtual Realities: Best Practices and Common Pitfalls of Adopting Virtual Lab Automation

Virtual Lab Automation (VLA) is a ground-breaking technology that promises quantifiable benefits for application development and test organizations, including faster lab deployment, less manual setup work, greater resource flexibility and utilization, and easier reproduction of defects. In this article, Skytap's Ian Knox discusses the best practices and common pitfalls associated with adopting a VLA solution. In addition, he outlines the steps to evaluate a virtualization solution for your test organization and provides further resources to help you get started.

The Trouble with Derivation

This article discusses the dark underbelly of derivation: the fragile base class. It's possible to modify a base class in such a way that, even though you've improved its implementation and all your tests work just fine, you've nonetheless damaged the derived classes, perhaps fatally.

Resistance Is Futile

Why do so many people resist change, even when that change will be for the better? It's simple, really. Every change ends something, and endings mean loss. People don't like loss. Even the best changes mean something familiar will end.

Understanding Software Performance Testing Part 1

Most people don't fully understand the complexities and scope of a software performance test. Too often performance testing is assessed in the same manner as functional testing and, as a result, fails miserably. In this four-part series we will examine what it takes to properly plan, analyze, design, and implement a basic performance test. This is not a discussion of advanced performance techniques or analytical methods; these are the basic problems that must be addressed in software performance testing.

Reloadable Test Data-O-Matic

Reloadable test data takes more time up front (as compared to on-the-fly data creation), but saves blood, sweat, and tears in the long term. It also virtually eliminates "works on my machine" bugs, creates a more intricate and realistic environment, and is the first step on the road to test automation.

Off the Trails

A focused approach toward testing a product is important, but sometimes we discover information that we didn't anticipate at all. One of the key skills in testing is dynamically managing our focus; sharpening it sometimes and widening it at other times. If we vary our approaches, we might find something surprising and broaden our coverage.

Taming the Headless Beast: A Proven Strategy for Testing Web Services

The benefits of Web services are becoming widely demonstrated and accepted. However, these benefits are not without their own challenges. How can you enter data and verify the response of a system without a GUI? Are you ready to tame this headless beast?

Risk-based Testing in Action

Risk-based testing allows project teams to focus their limited test efforts on the areas of the product that really matter, based on the likelihood of bugs in those areas and the impact of bugs should they exist. By using risk priority to sequence test cases and allocate test effort, test teams can also increase their chances of finding bugs in priority order and allow for risk-based test triage if necessary.

Lucky and Smart

Charles Darwin was certainly a great scientist, but his career and his discoveries were also strongly influenced by serendipity and luck. What could this great explorer and scientist teach us about testing?
