    Agile Interaction Design and Test-Driven Development of User Interfaces – A Literature Review
    (Springer, 2010) Hellmann, Theodore D.; Hosseini-Khayat, Ali; Maurer, Frank
    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 presented, including a thorough analysis of the current role of prototyping and current attempts to facilitate test-driven development of GUI systems, as presented in academic 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 associated 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 testable GUI-based applications by agile teams.

    Test-Driven Development of Graphical User Interfaces: A Pilot Evaluation
    (Springer, 2011) Hellmann, Theodore D.; Hosseini-Khayat, Ali; Maurer, Frank
    This paper presents a technique for test-driven development of GUI based applications, as well as a pilot evaluation. In our approach, user interface prototypes are created in such a way as to allow capture/replay tools to record interactions with them. These recordings can then be replayed on the actual GUI as it is being developed in a test-driven fashion. The pilot evaluation found that developers integrated GUI tests, based on user interface prototypes,into their development process and used them as a way to determine when a feature is actually complete.Study participants felt that TDD of GUI based applications is useful.
