JTorX: Exploring Model-Based Testing

The overall goal of the work described in this thesis is: ``To design a flexible tool for state-of-the-art model-based derivation and automatic application of black-box tests for reactive systems, usable both for education and outside an academic context.'' From this goal, we derive functional and non-functional design requirements. The core of the thesis is a discussion of the design, in which we show how the functional requirements are fulfilled. In addition, we provide evidence to validate the non-functional requirements, in the form of case studies and responses to a tool user questionnaire. We describe the overall architecture of our tool, and discuss three usage scenarios which are necessary to fulfill the functional requirements: random on-line testing, guided on-line testing, and off-line test derivation and execution. With on-line testing, test derivation and test execution takes place in an integrated manner: a next test step is only derived when it is necessary for execution. With random testing, during test derivation a random walk through the model is done. With guided testing, during test derivation additional (guidance) information is used, to guide the derivation through specific paths in the model. With off-line testing, test derivation and test execution take place as separate activities. In our architecture we identify two major components: a test derivation engine, which synthesizes test primitives from a given model and from optional test guidance information, and a test execution engine, which contains the functionality to connect the test tool to the system under test. We refer to this latter functionality as the ``adapter''. In the description of the test derivation engine, we look at the same three usage scenarios, and we discuss support for visualization, and for dealing with divergence in the model. In the description of the test execution engine, we discuss three example adapter instances, and then generalise this to a general adapter design. We conclude with a description of extensions to deal with symbolic treatment of data and time

An Integrated Formal Task Specification Method for Smart Environments

This thesis is concerned with the development of interactive systems for smart environments. In such scenario different interaction paradigms need to be supported and according methods and development strategies need to be applied to comprise not only explicit interaction (e.g., pressing a button to adjust the light) but also implicit interactions (e.g., walking to the speaker’s desk to give a talk) to assist the user appropriately. A task-based modeling approach is introduced allowing basing the implementing of different interaction paradigms on the same artifact

Improving Access and Mental Health for Youth Through Virtual Models of Care

The overall objective of this research is to evaluate the use of a mobile health smartphone application (app) to improve the mental health of youth between the ages of 14–25 years, with symptoms of anxiety/depression. This project includes 115 youth who are accessing outpatient mental health services at one of three hospitals and two community agencies. The youth and care providers are using eHealth technology to enhance care. The technology uses mobile questionnaires to help promote self-assessment and track changes to support the plan of care. The technology also allows secure virtual treatment visits that youth can participate in through mobile devices. This longitudinal study uses participatory action research with mixed methods. The majority of participants identified themselves as Caucasian (66.9%). Expectedly, the demographics revealed that Anxiety Disorders and Mood Disorders were highly prevalent within the sample (71.9% and 67.5% respectively). Findings from the qualitative summary established that both staff and youth found the software and platform beneficial

Tennyson and the Fabrication of Englishness

Nineteenth-century preoccupation with the meaning of Englishness began with the origin of the term in 1804. By the late nineteenth century, an ideology of Englishness had been established which was both reflected in and shaped by cultural forms and emerging myths in general and Tennyson’s poetry in particular. Critics identified Tennyson as an English poet from the first reviews of his published poems in the late 1820s. As Poet Laureate for over forty years, Tennyson became the authoritative public voice of English poetry. This thesis examines Tennyson’s ‘domestic poetry’ - his portrayals of English nature and landscape, monarchy, medievalism, and the ‘English Empire’ - written throughout his career and in their changing nineteenth-century context - to confirm that many representations of England and the English were more idealized than real, hence fabrications. However, the thesis argues that Tennyson’s representations of Englishness are complex and often conflicting fabrications, revealing ideological and personal faultlines. Although Tennyson’s oeuvre reveals an enduring love of English nature and landscape, poetic imagery suggests a qualified commitment to the developing ideology of rural England. His poems of monarchy mirror and enhance increasing public veneration of monarchy and fail to acknowledge the continuing co-existence of radical and republican sentiment. Tennyson’s Arthurian poems reveal that emerging gendered moralities were mythologized and both supported and qualified by revived interest in medievalism. Nineteenth-century concepts of Englishness were increasingly shaped by the imperial project and related questions of race. Tennyson’s attitude to the ‘English Empire’ changed from early ambivalence to resounding defence of ‘ever-broadening England’. Ultimately therefore Tennyson attained an imperial position in poetry in both senses of the term. This study confirms that the poet both reflected and shaped defining ‘moments of Englishness’ throughout his career and concludes that a significant defining moment of nineteenth-century Englishness was the birth of Alfred Tennyson in 1809
