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.

Abstract-This paper aims to explicate the method for test case generation in real-time systems. In software engineering, software design phase has the diagrammatic way to understand the real-time systems. The process of software testing to identify the defects and uncovered error as much as possible. Testing the real-time systems has more difficult process because the real-time system programs are adjacent to the hardware device. In this real -time system controls an environment by receiving data, processing and returning the processed data. These systems are simulation process with timing constraint so effective path coverage criteria are required. The testing may be poorly implemented which shows in a low-quality software or more time and cost wastage. A test case plays an important role in software testing. The applicable test cases have been used for generation of test scenarios and test data for realtime systems. This survey puts forward a discussion of research approaches and techniques based on functional specification i.e. behavioural diagram based test cases and structural diagram based test cases. This paper has been classifying the various intermediate approaches that are used to generate a test case for real -time systems notwithstanding discuss the test coverage criteria and major issues applicable to these approaches.Keyword-Real -time system, Model based test case generation, Embedded system I. INTRODUCTION In the real-time digital world, the software has played an important role in our society. We are increasingly dependent on software because the software to run perfectly in our day to day lives. Real-time software needs perfect testing during the software development phase. The software can be tested either automatically or manually. A traditional testing method based on hand work is low efficiency and carried out more time and cost. Automated software testing are consumes more than 50% of the costs that are associated with the software development. Automated software testing can bring us a lot of advantages, which make it easier to find bugs. The automated testing is fully based on test cases. Over the past years, the test case generation approaches have faced many trials to produce efficient automated test cases [1]. The research community presented many approaches to generate the test cases from the functional specification. The design specification allows trimming the error in the early stage of software development. The real-time systems to be coupled with behavioural and structural specifications. An embedded system generally uses microprocessors and integrated circuits that contain many functions. Most of the embedded systems designed for life or safety critical system. The effective path coverage is required in the development process. The execution of embedded real-time system with an object-oriented program is expressed to represent a dynamic view of behaviour and structural in Unified Modelling Language (UML) and some of the structural specification in the Functional block diagram (F...

Test sequence generation is considered as an important phase of testing. Test sequences can be generated either by using code or model. Test sequence generation can be automated to make testing easier. This paper presents an approach for automatic test sequence generation from UML activity diagram of the Java7 Fork/Join framework. The activity diagram is first converted to an XML file, which is then traversed to find test sequences. Infeasible test sequences are avoided in this approach.Cost and overheads involved are also very less.
