Based on the analysis of current conditions and shortages of the configuration files management in smart substation, the problems existing in current conditions are proposed, such as: ICD test technology, SCD test technology, SCD difference comparison technology. In order to meet the demand of the large scale smart substation construction, a solution of building the smart substation configuration...
Credit scoring is an important process in every financial institution and bank. Its high accuracy in classifying customers helps decrease the credit risk and increase reliability and profit. In this paper, we propose a binary classification approach that can classify customers who apply for loans. A statistical technique called Stepwise Regression (SR) is used as a pre-process to select important...
Previous work has demonstrated that property-based testing (PBT) is a flexible random testing technique that facilitates the generation of complex form data. For example, it has been shown that PBT can be applied to web-service applications that require various inputs for web-forms. We want to exploit this data generation feature of PBT and combine it with an external test-case generator that can...
Data-intensive systems in e-governance collect and process data to ensure conformance to a set of business rules. Testers meticulously verify data in test databases, extracted from different steps of a live production stream , for correct application of business rules. We simplify the process by allowing testers to model a test domain on a relational database and automatically generate test cases...
Web service composition involves a collection of web services; the interaction among the participating services makes the testing of the web service composition significantly complicated. In this paper, we present an approach of test case generation for Business Process Execution Language (BPEL) based web service composition using Colored Petri Net (CPN) which provides a strong formal background for...
To ensure the delivery of high quality and robust service-oriented applications, testing of web services composition has received much attention. These services have become more and more complex, where they have to cope with strict requirements of business processes and their dynamic evolution, and interactions among different companies. In this context, the analysis and testing of such services demands...
An agent-based elevator simulation was implemented to test the validity of an advertisement scheduling system. The elevator simulation imitates the elevators and their advertisement system, thus testing the different schedules and sending the results back to the scheduler. To validate the results, certain data sets of the simulation application are compared with expected values. First results have...
All the domain and vertical applications are scaled up to the Big Data applications because of the volume, variety, velocity of growing real time data. This necessitates the streamlining and alteration in the business processes, software development methodologies, infrastructure of distributed parallel processing, data modeling, data analysis, applications, services as well on the testing. The traditional...
In the rapidly growing field of Big Data, we note that a disproportionately larger amount of effort is being invested in infrastructure development and data analytics in comparison to applications software development -- approximately a 80:20 ratio. This prompted us to create a context model of Big Data Software Engineering (BDSE) containing various elements -- such as development practice, Big Data...
Testing data-intensive systems is paramount to increase our reliance on information processed in e-governance, scientific/ medical research, and social networks. A common practice in the industrial testing process is to use test databases copied from live production streams to test functionality of complex database applications that manage well-formedness of data and its adherence to business rules...
This paper studies the performance test in big data application. The existing performance testing technology is not suitable for the big data application. The paper proposed test technology for performance testing. The technology provided test goal analysis, test design, load design for big data application. The character for different application could be supported to consider specific multiple test...
This industrial contribution describes a tool support approach to assessing the quality of relational databases. The approach combines two separate audits - an audit of the database structure as described in the schema and an audit of the database content at a given point in time. The audit of the database schema checks for design weaknesses, data rule violations and deviations from the original data...
The rapidly changing IT economy has influenced the Business Intelligence (BI) systems to look at innovative ways to be equally fast and flexible. There is a need to be more intuitive and quick in implementation so as to adapt to the changing environment. One of the ways by which organizations can achieve these goals is by using Agile based BI development models. There are many components in a successful...
The use of web services integrated in different applications, especially the composition of services, brings challenges for testing due to their complex interactions. In this paper, we propose an event-based approach to test web service compositions. The approach is based on event sequence graphs which we extend by facilities to consider the specific features of web service compositions. An enterprise...
This paper reports on ongoing work on SWAT, a new toolkit for security workflow analysis. SWAT provides a platform for the realization and testing of well-founded methods to detect information leaks in workflows, both for the workflow certification and for audit based upon the execution traces. Besides presenting the SWAT's functionality and high-level architecture, an example illustrates its operation.
with the development of supply chain and logistic, the commodity classification and amount provided by E-commerce system rise increasingly. The traditional web-centered searching commerce model has become the bottleneck hindering value-adding of e-commerce enterprises, while personalized e-commerce system is one effective way to solve this problem. Incorporating the demand for personalized e-commerce...
This paper proposes a novel approach to generating test cases from UML 2.0 activity diagrams and prioritizing those test cases using model information encapsulated in the activity diagrams. The test cases generated according to our approach are suitable for system level testing of the application. For prioritization of test cases, we propose a method based on coverage of all transitions in the activity...
This paper presents a case study for the modeling and model-based testing (MBT) of enterprise service choreographies. Our proposed MBT approach uses proprietary models called Message Choreography Models (MCM) as test models. The case study illustrates how MCM-based service integration testing allows to formalize design decisions and enables full integration into an existing industrial test infrastructure...
This paper describes a model for capturing service designs and the design of service product lines. The model promotes reuse of service artifacts, enables a balanced view of the service from different stakeholder viewpoints, and provides a foundation for design for service quality. The model leverages a phased approach to design, engineering and management of services. The model has applicability...
With the increasing number of service oriented system implementations, new challenges concerning their development and testing are emerging.This paper presents an approach for model-driven system testing of service oriented systems. The approach offers a systematic testing methodology and it is based on tightly integrated system and test models with a formal metamodel. The test code generation itself...
