This chapter describes the development of GUI-based applications, from usability engineering and prototyping to acceptance test-driven development, in an agile context. An overview of current agile interaction design practices will be pre-sented, including a thorough analysis of the current role of prototyping and current attempts to facilitate test-driven development of GUI systems, as presented in aca-demic and industrial literature.
Traditional usability engineering approaches shows that if user input is taken into consideration early in the development process by repeatedly conducting usability tests on low-fidelity prototypes of the GUI system, the final version of the GUI will be both more usable and less likely to require revision. The major risk asso-ciated with test-driven development of GUIs is the high likelihood of change in the target GUI, which can make test development unnecessarily expensive and time consuming. A unification of these styles of development will be presented, along with a prediction of how this process can be used to simplify creating test-able GUI-based applications by agile teams.
