Interconnecting different wireless sensor and actuator network in the real-time systems are more demanding for testing. High capability is needed to enable efficient methodologies for testing. The major source of effective testing is the identification of test cases. Programming instruction based test case generation has not well suitable for Arduino real-time systems, that an open statement in the research community. This paper introduces a functional block diagram based test case generation framework to facilitate the functional evaluation of Arduino real-time systems. It makes from the functional block diagram. First, block diagrams are converted to the Event Sequence Graph, then the event node is minimized, the test cases are generated minimized event. The presented methodology has validated with the Arduino programming language. This proposed approach quantified with five sensors based Arduino real-time system experiments shows that based on the validated test cases; the development time and cost of the Arduino real-time systems have dynamically reduced. HIGHLIGHTS Software testing results ensure the quality of the developed software. Programming instruction based testing has not well suitable for Arduino real-time systems Arduino functional block diagrams are converted to the event node for test case generation. Event Sequence Graph conversion algorithm provide the event direction Validation of Arduino software programming based on Arduino functional block diagrams identify the new fault detection capability GRAPHICAL ABSTRACT

In the current researching and Industrial fields have focused on much-attracted technology is chatbots. Informal agents could provide an appropriate and economic environment in online between the users and service provider. Due to a large number of datasets based on the digital tools, the user’s queries based satisfying responses providing are critical in the service oriented chatbots. The successful human-chatbots interaction must be apparent and reacted by the user. This paper presents a technique to generate the test path for effective chatbot software testing. Identification of relations among the chatbots, transformations, and boundaries of the existing methodology are described. This experimental results associated with four peak chatbot response methodologies along with technology specifications. An in-depth experimental of proposed chatbot test path generation methodology, provides the experimental results and comparison.

Software testing of the real-time system (RTS) software based on specification diagram has a necessary sequence of parallel events for generation of test cases. In the model-based test case generation for RTS both automated and manual is limited in techniques as some situations inadvertently forget the simulation events. Many meta-heuristic techniques have solved the problem in RTS test cases generation. However, the technique seems to have much more focus on the optimum solution. This paper presents a methodology based on timed input-output event of specification diagram that supports a wide range of possible test cases for RTS application software. The proposed method applies for automated test case generation tool aims at validating the executable code and covers the systems behaviours in an optimized manner. The methodology is tested with three different RTS software such as client-server based real-time transaction, embedded based real-time sequence and sensor based real -time events. This proposed approach, based on the executable test cases, dynamically increases the productivity of the real-time systems.
