Hans Buwalda

Hans Buwalda is an internationally recognized expert in test development and testing technology management and a pioneer of keyword-driven test automation. He was the first to present this approach, which is now widely used throughout the testing industry. Originally from The Netherlands, Hans now lives and works in California as CTO of LogiGear Corporation, directing the development of what has become the successful Action Based Testing™ methodology for test automation and its supporting TestArchitect™ toolset. Prior to joining LogiGear, Hans served as project director at CMG (now CGI) in the Netherlands. He is co-author of Integrated Test Design and Automation and a frequent speaker at international conferences.

Five Misconceptions about Test Automation

Hans Buwalda describes five of what he refers to as misconceptions about test automation.

Improving Application Testability

Automating functional testing is almost never easy. As testers, how we organize and design tests has a big impact on outcomes, but developers can—and should—have a role in making automation easier. This ease or lack of ease is part of what is known as "testability."

Improving Test Automation—What About Existing Tests?

A good test design is important because it improves the quality of the tests, helping to add breadth and depth, and it facilitates efficiency, in particular for automation. These points are obvious when starting a project from scratch, but what do you do when tackling a project with existing tests?

Designing Data-Driven Tests with Keywords for Automation Success

When automated tests are well-organized and written with the necessary detail, they can be very efficient and maintainable. But designing automated tests that deal with data can be particularly challenging. Tests need certain base data to be available and in a predictable state when they run.

Test Design for Automation: Anti-Patterns

Just like with design patterns, anti-patterns can benefit from a short and catchy name to make them easy to remember and talk about. Hans Buwalda shares a list of typical situations seen in tests that can harm automation and names for them.

Scalability of Tests—A Matrix

Hans Buwalda highlights the scalability of unit, functional, and exploratory tests—the three kinds of tests used to verify functionality. Since many automation tools and strategies traditionally focus on functional testing, Hans provides some strategies to make functional testing more manageable.

Using Keywords to Support Behavior-Driven Development

Behavior-driven development tests can be efficiently automated with keywords, avoiding the need of a programming language and minimizing the involvement of developers. Hans Buwalda details how to support BDD scenarios with actions and keywords and switch between formats depending on your needs.
