First, we design an SOA-based application using OpenEsb tool. That application is supplied to code converter to get XML code of the designed application. Then, we have supplied this XML code to Tcases tool to generate test cases according to black-box testing technique. These test cases are supplied to Hit Ratio Calculator to compute Hit Ratio percentage. On an average of four SOA-based applications, we achieved Hit Ratio percentage as 63.94%.

This can be done by separating the concern in a clean and explicit way. Each of the concern can be addressed by partitioning a software system into modules. Concerns are clearly identifiable with a special linguistic construct called Aspects, which has been introduced by a new programming paradigm known as aspect-oriented programming. No doubt aspect-oriented programming brings lots of opportunities for the software developer. On the other hand, it is very difficult for analysing those programs for different software engineering activities. In such scenario, slicing plays a vital role. This paper proposes an approach to compute the dynamic slices of aspect-oriented programs. In our approach, we have introduced different level dependence graphs, such as aspectoriented statement level dependence graph, aspect-oriented method level dependence graph, aspect-oriented AC weaving level dependence ...

Modeling technology has been introduced into the software testing field. However how to carry through the testing modeling effectively is still a difficulty. Based on the combination of simulation modeling technology and dependability we have proposed an approach to generate test cases. In our approach, first, the system is modeled in MATLAB using Simulink/ Stateflow tool. After the model creation we verify that system and generate a dependency graph of that system. From that graph we generate test sequences.

MC/DC is a white box software testing criteria aiming to prove all the conditions involved in a predicate that can influence the predicate value in the desired way. Though MC/DC is a coverage criterion, existing automated test data generation approaches like CONCOLIC testing do not support MC/DC. In this paper, we propose an automated technique to generate a test suite that helps in achieving an increase in MC/DC coverage of a program under test. We use code transformation technique which consists of two steps: identification of predicates and generation of empty truefalse if-else statements. The empty conditional statements are based on the concepts of exclusive nor (X-NOR) operations. This transformed program is inserted into the CREST TOOL. It drives CREST TOOL to generate test suite and increase the MC/DC coverage. Our technique helps to achieve a significant increase in MC/DC coverage as compared to traditional CONCOLIC testing.

Web 3.0 in this field has been a major invention done till this date. Yet semantic web proposes to be a good choice for its enhancement towards searches based on intent of user. There has been lots of techniques proposed so far still methods are been searched based on this concept. Methods: Surfing the internet for relevant information as needed by the user has therefore become an issue for users. In order to overcome the problem of information deluge for relevant information retrieval, there is a need to devise a way to search data based on user's intent. This is where semantic search comes into play. Findings: In order to improve quality of search correctness, semantic search tries to interpret the context of data provided along with user's intent, location from where that has been looked for, variation of words etc. As a part of our work we have proposed a model using natural language processing that aims to classify data based on semantic relevance to user query. The well-known concept of NLP permits the machines to derive the purpose or the meaning meant by humans or natural language input. The aim is to provide exact needed result to the user in place of making him to look for it all over the URLs given as result. Improvements/Applications: Tools based on this semantic knowledge will increase relevance of search engines along with the less list of documents o go through by the user or surfer for a specific result.

It is the tenth largest language as scheduled in the constitution part-VIII of India. Odisha has very old history and rich culture; its heritages are present in form Odia language text. So to mine and extract useful information of this language sentiment analysis has been used. Sentiment analysis technique is used for identifying the emotions behind the given text to understand the attitude, opinion and emotions expressed in the language. This paper investigates Sentiment analysis of Odia text using supervised classification techniques. We applied simple Naive Bayes (NB), Logistic Regression and SVM on Odia text and evaluate its effect. This system takes the Odia movie reviews and gives you the unbiased sentiments of the people in positive and negative polarity. Three evaluation measure accuracy, precision and recall is used, on which system performance is computed and compared. The experimental result demonstrate the superiority of the logistic regression model.

It is likely that some test cases execute the program parts that are more prone to errors and will detect more errors if executed early during the testing process. Finding an optimal order of execution for the selected regression test cases saves time and cost of retesting. This paper presents a static approach to prioritizing the test cases by computing the affected component coupling (ACC) of the affected parts of object-oriented programs. We construct a graph named affected slice graph (ASG) to represent these affected program parts. We determine the fault-proneness of the nodes of ASG by computing their respective ACC values. We assign higher priority to those test cases that cover the nodes with higher ACC values. Our analysis with mutation faults shows that the test cases executing the fault-prone program parts ...

We use the features in UML 2.0 sequence diagram including conditions, iterations, asynchronous messages and concurrent components. In our approach, test cases are derived from analysis artifacts such as use cases, their corresponding sequence diagrams and constraints specified across all these artifacts. We construct Use case Dependency Graph (UDG) from use case diagram and Concurrent Control Flow Graph (CCFG) from corresponding sequence diagrams for test sequence generation. We focus testing on sequences of messages among objects of use case scenarios. Our testing strategy derives test cases using full predicate coverage criteria. Our proposed test case generation technique can be used for integration and system testing accommodating the object message and condition information associated with the use case scenarios. The test cases thus generated are suitable for detecting synchronization and dependency of u...

Software testing is necessary to produce highly reliable systems. The use of a model to describe the behavior of a system is a proven and major advantage to test. In this paper, we focus on model-based testing. The term model- based testing refers to test case derivation from a model representing software behavior. We discuss model-based approach to automatic testing of object oriented software which is carried out at the time of software development. We review the reported research result in this area and also discuss recent trends. Finally, we close with a discussion of where model-based testing fits in the present and future of software engineering.

Data Mining aims at the automatic discovery of underlying non-trivial knowledge from datasets by applying intelligent analysis techniques. The interest in this research area has experienced a considerable growth in the last years due to two key factors: (a) knowledge hidden in organizations databases can be exploited to improve strategic and managerial decision-making; (b) the large volume of data managed by organizations makes it impossible to carry out a manual analysis. The book addresses different methods and techniques of integration for enhancing the overall goal of data mining. The book helps to disseminate the knowledge about some innovative, active research directions in the field of data mining, machine and computational intelligence, along with some current issues and applications of related topics.
Data flow testing of feature-oriented programs

But AOP has a lot of features like aspects, advices, point-cuts, join-points etc., and because of these the usage of the existing intermediate graph representations is rendered useless. In our work we have defined a new intermediate graph representation for AOP. The construction of SDG is automated by analysing the bytecode of aspect-oriented programs that incorporates the representation of aspect-oriented features. After constructing the SDG, we propose a slicing algorithm that uses the intermediate graph and computes slices for a given AOP. Program slicing has numerous applications in software engineering activities like debugging, testing, maintenance, model checking etc. To implement our proposed slicing technique, we have developed a prototype tool that takes an AOP as input and compute its slices using our proposed slicing algorithm. To ev...

Nowadays, slicing of object-oriented programs has picked up the momentum as most of the real world programs are object-oriented in nature. The algorithms which are available of-the-self, address different issues in their own ways. In this paper, we propose a new algorithm which incorporates graph coloring technique. But in order to compute the dynamic slice, we have contradicted some key constraints of graph coloring algorithm. The advantage of our algorithm is that it is faster and the process of computing slice can be optimized further.

Test data generation is one of the key issues in software testing. This paper proposes an reduction approach to test data generation for the state-based software testing. In this paper, first state transition graph is derived from state chart diagram. Then, all the required information are extracted from the state chart diagram. Then, test cases are generated. Lastly, a set of test cases are minimized by calculating the node coverage for each test case. It is also determined that which test cases are covered by other test cases. The advantage of our test generation technique is that it optimizes test coverage by minimizing time and cost. The present test data generation scheme generates test cases which satisfy transition path coverage criteria, path coverage criteria and action coverage criteria. A case study on Railway Ticket Vending Machine (RTVM) has been presented to illustrate our approach.

We use a dependence based intermediate program representation called Aspect System Dependence Graph (AOSG) to represent aspect-oriented programs. Then, we propose the dynamic slicing algorithm for AOPs, which is an extended version of EMDS algorithm for object-oriented programs. Our algorithm is based on marking and unmarking of the edges of AOSG appropriately during runtime.
