Bug Counts vs. Test Coverage

Occasionally, we encounter projects where bug counts simply aren't as high as we expect. Perhaps the product under test is in its second or third release cycle, or maybe the development team invested an inordinate amount of time in unit testing. Whatever the reason, low bug counts can be a cause of concern because they can indicate that pieces of functionality (which potentially contain bugs) are being missed. When low bug counts are encountered, management may begin to wonder about the quality of testing. This article covers techniques for dealing with low bug counts, and methods for reassuring management that coverage is being achieved.

Can You Negotiate Quality?

XP teams have the right to do their best work. On the other hand, customers have the right to specify and pay for only the quality they need. How does one reconcile two potentially conflicting points of view? Is quality negotiable? If so, how do we go about negotiating it? This paper will explore the following questions: Is quality negotiable? How can we negotiate quality? What are internal and external quality, and are either or both negotiable? What's the XP tester's quality assurance role? How far should testers go in helping the customer define acceptance criteria?

The 11th Hour

Testers are often on the critical path for getting a software release out. They must plan carefully in order to minimize the critical path, while still doing a complete job of testing. This schedule pressure is taken to an extreme when a production server must be taken offline in order to deploy the software, and everyone is waiting for the final test results before the system can go live again. Karen Johnson describes her company's carefully planned and orchestrated method for doing a final check of an installed system. Her story is relevant to e-commerce companies as well as IT shops that are under pressure to keep systems updated while minimizing downtime.
