Testing changes to an existing system is more difficult than testing new code because of the danger that a change will inadvertently break something else. Studies show that, compared to new code, changes are ten times more likely to contain bugs. This class presents the special techniques needed for testing changes to the system, whether those changes are enhancements or bug fixes. Regression testing is a simple concept. The problem is that there are a large number of pitfalls which are expensive to uncover by experience. It's easy to do regression testing almost right, which turns out to have serious consequences. Symptoms include large test sets of unknown content, lots of redundant tests, and bugs that slip through even though we supposedly used regression testing to eliminate the side effects of changes. This course will show you how to avoid the pitfalls, using proven techniques and tips to build and manage your Regression Test Set (RTS). This key tool ensures that what used to work before a change is made still works after the change. By understanding how to control the effect of changes, you'll be able to keep the RTS small, easy to use, and effective. Using these techniques on a continuing basis will ensure that software changes will do what they're supposed to do - and nothing else. Who Should Attend: This course is valuable for quality assurance and testing staff, programmers, system users with testing responsibility, systems analysts, and project managers.
