March QASIG Meeting

Abstract:

We may think we are ready to move onto new and innovative features. However, if we do not deal with the past, it can easily come back to haunt, slowing down new projects, and robbing our testing time unexpectedly, often to the point that testing becomes the bottleneck that slows innovation to a crawl.

For those of us who work on software that already exists, exciting new functionality and improvements are the main things that drive upgrades, as well as compatibility with new platforms. However, if end users cannot trust the quality of the legacy features they rely on, they will be reluctant to upgrade, or worse, your new versions will get a reputation of being unstable - harming overall adoption. In some cases users may downgrade their software to an earlier version because they are unhappy with the quality of the newer release or request an earlier version they feel is reliable.

This paper presentation is about the subjective and difficult part of testing which has no provable mathematical correct answer. It is about risk management, test planning, cost, value, and being thoughtful about which tests to run in the context of your specific project. The discussion covers identifying and reducing test case bloat, when it can be done, who does it, along with a few examples used in practice.

Furthermore, it will cover one untested but under test theory, experiences shared in significantly reducing test cases to cover more than three times the applications when the test team reduced from sixteen to four testers. When facing increasingly complex software and growing software, we must balance testing existing features that customers rely on every day with new features and interactions. When balanced in a sensible way, the best of the legacy test cases can be maintained, using existing knowledge to reduce risk as much as possible.

About our speaker: Lanette Creamer is a test lead with 10 years industry experience ranging from product feature testing on early versions of InDesign to leading collaborative end to end workflow testing across the Adobe Creative Suites. Most recently Lanette has been testing on an agile team that is automating the software production process between a product build and actual shipment, to be used on all Adobe shipping products in 2010. Lanette has two published technical paper "Testing for the User Experience", voted best paper by presentation attendees at PNSQC 2008 and "Reducing Test Case Bloat", PNSQC 2009. Her magazine article "9 Ways to Recruit Testers for Collaborative Test Events" was published in Software Test and Performance Magazine, in the January 2010 issue. Lanette started writing a testing blog at http://www.testyredhead.com in 2006 and has been writing and collaborating with the online testing community non-stop since.
