- Context-aware applications are emerging applications in the modern era of computing. These applications can determine and adapt to situational context to provide better user experience. Testing these applications is not straightforward and poses several challenges such as developing context-aware test cases and generating test data etc. However, by employing model based testing technique, testing process for context-aware applications can be automated. To achieve maximum degree of automation, it is necessary to automate model transformation, test data generation and test cases execution. To execute test cases, test data is required and developing test data for context-aware applications is a challenging task. The aim of this study is to address this issue; thus, we propose automated test data generation for functional testing of context-aware applications. This automated test data generation can reduce testing time and cost, thus enabling test engineers to execute more testing cycles to attain higher degree of test coverage.

- Software testing aims at ensuring the quality of a software product. Context-aware applications are emerging applications that are capable to sense their environment and adapt to situational context to provide better user experience. Context-aware applications pose many challenges for software testing such as defining test adequacy criteria, generating test data, developing context-aware test cases etc. Test case generation process for context-aware applications can be automated using a model based testing technique. To attain this goal with maximum degree of automation, it is required to transform development model into a test model automatically. In this study, we propose a typecast of activity node of UML activity diagram, called Context-Aware Activity for modelling context-aware applications. We have also developed an approach for automatic transformation of the development model i.e., UML activity diagram with Context-aware Activity typecast into a testing model i.e. function nets. This testing model is used to automate test case generation and we have illustrated how to generate context-aware test cases using our proposed approach.

- Mechanical systems in cars are replaced by electronic equivalents. To be authorized for the road, validation that the replacements are at least as good as the old systems is required. For electronic braking systems (brake-by-wire), this goodness translates to safety in terms of maintaining timing constraints. Yet, in the future, the safety of braking maneuvres will depend, not only, on electronic brakes, but also on cooperative driving maneuvres orchestrated among many cars. Connecting both brake-by-wire on the microscopic level with cooperative braking on the macroscopic level allows for determining safety on a broader scale, as both systems feed from the same resource: Time. This paper discusses work-in-progress, introducing and combining two threads: electronic brakes and cooperative braking. Discussing safety on two levels simultaneously motivates connecting a Simulink model of an electronic brake-by-wire system with the traffic simulator SUMO for conducting the required combined validation. How safe is a car in relation to a given maximal braking distance? What is the optimal distribution of reaction time between electronic brakes and cooperative braking? The validation focuses on non-functional safety limited by temporal constraints (translated to braking distance). It can be exploited in an early validation approach to help reduce costs of more expensive real world experimentation. It can also determine the boundaries at which sufficient safety can be guaranteed. © 2017 IEEE.
