Chapter 8. Extreme Testing
In the 1990s a new software development methodology termed Extreme Programming (XP) was born. A project manager named Kent Beck is credited with conceiving the lightweight, agile development process, first testing it while working on a project at Daimler-Chrysler in 1996. Although several other agile software development processes have since been created, XP is by far the most popular. In fact, numerous open-source tools exist to support it, which verifies XP's popularity among developers and project managers.
XP was likely developed to support the adoption of programming languages such as Java, Visual Basic, and C#. These object-based languages allow developers to create large, complex applications much more quickly than with traditional languages such as C, C++, FORTRAN, or COBOL. Developing with these languages often requires building general-purpose libraries to support your efforts. Methods for common tasks such as printing, sorting, networking, and statistical analysis are not standard components. Languages such as C# and Java ship with fullfeatured application programming interfaces (APIs) that eliminate or reduce the need for custom library creation.
However, with the benefits of rapid application development languages come liabilities. Although developers were creating applications much more quickly, the quality was not guaranteed. If the application worked, it often failed to meet the program specification. The purpose of the XP development ...
