Automated Test Generation

The challenge for testers: reduce the testing interval without reducing quality. One answer: find a new way to approach test design and test generation. This paper will discuss an ongoing Lucent Technologies experiment in automated test generation from a behavioral model of the software product under test. Results indicate that our new approach can increase the effectiveness of our testing while reducing the cost of test design and generation.

Mutation Testing: A New Approach to Automatic Error-Detection

Mutation Testing is a powerful method for finding errors in software programs. This paper will describe the process of mutation testing and how a new approach to this technology benefits the software industry.

When Should a Test Be Automated?

The question is how to make a rational decision about which tests to automate. When I take a job as a contract tester, I typically design a series of tests for some product feature. For each of them, I need to decide whether that particular test should be automated. This paper describes how I think about the tradeoffs.

Teamwork Does Work: Testing and Quality in Large Development Projects

In 1993, we at USA Group chartered a project to replace its 15-year old student loan guarantee system. The new system was named EAGLE II and recently entered production. USA Group is driven by its software systems. As a consequence, software development is strategic to the company's success. We've had significant experience in creating and maintaining large systems. However, our experience in creating those previous systems left us looking for a better way.

T-shirts Are Not Enough

Watching the recent Olympic teams in their matching uniforms reinforced the value of connecting with your team. What other gear might your team need? I'm not sure where we got the idea that T-shirts were enough. Are we too arrogant to admit that sometimes a bulletproof vest would be handy?

Who Needs Management?!

I have heard testers lament about being managed by non-technical people who cannot tell the difference between a PC and a microwave oven (they both have windows, don't they?)! Managers believe in management, and we technical people believe in subtler, sophisticated, deep technology. The concept is simple. Then I was subjected to a harsh reality!

How to Plan the Perfect 'T' Party

Software professionals have long engaged in debate over software development processes. Much has been written about how to improve those processes-resulting in better-quality, faster-to-market products. Often neglected are the people who implement the processes. Developers and testers frequently seem to have adversarial relationships, although they share the same goal: high-quality software. No matter how good they are, the processes are unlikely to succeed if the participants fail to get along.

Implementing a Software Testing Methodology

Many of us are taking part or will take part in the process of implementing a software testing methodology or process at our organization. The size of the organization notwithstanding, the success of this type of implementation depends largely on management and enterprise support. U.S. Bancorp, Minneapolis, MN, is currently involved in implementing a new software testing methodology throughout the enterprise. My role, as the methodology project lead, is to help existing testing groups conceptualize how the methodology should be applied to their existing work. This effort is accomplished through both training and hands-on mentoring. There are valuable lessons that I have learned about choosing a testing methodology and the training efforts that follow such an endeavor. I would like to share them with you.

Running Down Assumptions

Do you think the assumptions you make about your software project are important? I do. One of the biggest sources of software project failure is hidden assumptions, especially about your requirements. These assumptions have a way of coming out of the woodwork–usually at the worst possible moment–to foil your projects. But there are ways to track down and expose assumptions.

Shhhhhh! You Can't Say That!

Treating symptoms instead of the root cause of symptoms is a mistake that dates back millennia (just ask Socrates). The current-day workplace is no different. In Johanna Rothman's column, we get a glimpse at what happens when a company doesn't value its people.
