Automated Functional Testing based on the Navigation of Web Applications
Web applications are becoming more and more complex. Testing such
applications is an intricate hard and time-consuming activity. Therefore,
testing is often poorly performed or skipped by practitioners. Test automation
can help to avoid this situation. Hence, this paper presents a novel approach
to perform automated software testing for web applications based on its
navigation. On the one hand, web navigation is the process of traversing a web
application using a browser. On the other hand, functional requirements are
actions that an application must do. Therefore, the evaluation of the correct
navigation of web applications results in the assessment of the specified
functional requirements. The proposed method to perform the automation is done
in four levels: test case generation, test data derivation, test case
execution, and test case reporting. This method is driven by three kinds of
inputs: i) UML models; ii) Selenium scripts; iii) XML files. We have
implemented our approach in an open-source testing framework named Automatic
Testing Platform. The validation of this work has been carried out by means of
a case study, in which the target is a real invoice management system developed
using a model-driven approach.Comment: In Proceedings WWV 2011, arXiv:1108.208
Interoperating Context Discovery Mechanisms
Context-Aware applications adapt their behaviour to the current situation of the user. This information, for instance user location and user availability, is called context information. Context is delivered by distributed context sources that need to be discovered before they can be used to retrieve context. Currently, multiple context discovery mechanisms exist, exhibiting heterogeneous capabilities (e.g. communication mechanisms, and data formats), which can be available to context-aware applications at arbitrary moments during the ap-plication’s lifespan. In this paper, we discuss a middleware mechanism that en-ables a (mobile) context-aware application to interoperate transparently with different context discovery mechanisms available at run-time. The goal of the proposed mechanism is to hide the heterogeneity and availability of context discovery mechanisms for context-aware applications, thereby facilitating their development
Framework for software architecture visualization assessment.
In order to assess software architecture visualisation strategies, we qualitatively characterize then construct an assessment framework with 7 key areas and 31 features. The framework is used for evaluation and comparison of various strategies from multiple stakeholder perspectives. Six existing software architecture visualisation tools and a seventh research tool were evaluated. All
tools exhibited shortcomings when evaluated in the framework
Multi-bot Easy Control Hierarchy
The goal of our project is to create a software architecture that makes it possible to easily control a multi-robot system, as well as seamlessly change control modes during operation. The different control schemes first include the ability to implement on-board and off-board controllers. Second, the commands can specify either actuator level, vehicle level, or fleet level behavior. Finally, motion can be specified by giving a waypoint and time constraint, a velocity and heading, or a throttle and angle. Our code is abstracted so that any type of robot - ranging from ones that use a differential drive set up, to three-wheeled holonomic platforms, to quadcopters - can be added to the system by simply writing drivers that interface with the hardware used and by implementing math packages that do the required calculations. Our team has successfully demonstrated piloting a single robots while switching between waypoint navigation and a joystick controller. In addition, we have demonstrated the synchronized control of two robots using joystick control. Future work includes implementing a more robust cluster control, including off-board functionality, and incorporating our architecture into different types of robots
