Visualizing test diversity to support test optimisation
Diversity has been used as an effective criteria to optimise test suites for
cost-effective testing. Particularly, diversity-based (alternatively referred
to as similarity-based) techniques have the benefit of being generic and
applicable across different Systems Under Test (SUT), and have been used to
automatically select or prioritise large sets of test cases. However, it is a
challenge to feedback diversity information to developers and testers since
results are typically many-dimensional. Furthermore, the generality of
diversity-based approaches makes it harder to choose when and where to apply
them. In this paper we address these challenges by investigating: i) what are
the trade-off in using different sources of diversity (e.g., diversity of test
requirements or test scripts) to optimise large test suites, and ii) how
visualisation of test diversity data can assist testers for test optimisation
and improvement. We perform a case study on three industrial projects and
present quantitative results on the fault detection capabilities and redundancy
levels of different sets of test cases. Our key result is that test similarity
maps, based on pair-wise diversity calculations, helped industrial
practitioners identify issues with their test repositories and decide on
actions to improve. We conclude that the visualisation of diversity information
can assist testers in their maintenance and optimisation activities
An evaluation framework to drive future evolution of a research prototype
The Open Source Component Artefact Repository (OSCAR) requires
evaluation to confirm its suitability as a development environment
for distributed software engineers. The evaluation will take note of
several factors including usability of OSCAR as a stand-alone system,
scalability and maintainability of the system and novel features not
provided by existing artefact management systems. Additionally, the
evaluation design attempts to address some of the omissions (due to
time constraints) from the industrial partner evaluations.
This evaluation is intended to be a prelude to the evaluation of the
awareness support being added to OSCAR; thus establishing a baseline
to which the effects of awareness support may be compared
