Many of the problems found in the uses of exception handling are caused by the lack of testing and a priori design of the exceptional behavior. As a consequence, exceptions flow in unforeseen ways during the execution of a software system, causing a negative impact on reliability. This paper presents a new agile approach to test the exceptional behavior of a system. It supports developers in checking...
As cloud services proliferate, it becomes difficult to facilitate service composition and testing in clouds. In traditional service-oriented computing, service composition and testing are carried out independently. This paper proposes a new approach to manage services on the cloud so that it can facilitate service composition and testing. The paper uses service implementation selection to facilitate...
As the number of mobile applications grows software quality becomes more and more an important issue in this realm. An appropriate mobile quality framework would serve developers as a guideline for quality assurance. In this work, we present an approach to a software quality framework for development of mobile applications. This framework is based on a mobile software quality model, defining key qualities...
Test driven development (TDD) is one of the basic practices of agile software development and both academia and practitioners claim that TDD, to a certain extent, improves the quality of the code produced by developers. However, recent results suggest that this practice is not followed to the extent preferred by industry. In order to pinpoint specific obstacles limiting its industrial adoption we...
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...
When explicitly considering the testability of software-centric systems, architects tend to be more conscious and thoughtful about their design decisions, be they related to modularization, interfaces, or design choices. The paper discusses how architects can use tests and test-driven development as a design tool. The goal is to avoid or discover architectural deficiencies before they're realized-when...
The article focuses on the introduction of SI-NS diagram technique, which can be applied in the whole process of software programming, developing, analyzing, testing, filing and maintaining. It is commonly acknowledged that software maintenance occupies 80% of the cost for a software development life cycle, and 80% of the program to be maintained is comparatively complex. Using the readable SI-NS...
In this paper, the personal financial assessment system of Industrial and Commercial Bank of China branch in Suzhou was used for a example, during the designing and testing in parallel, according to test results, we propose a method to calculate the satisfaction of the software system, to judge the performance of the system and to analysis the extent of the various stages of testing changes, then...
The eXtreme Programming (XP) software development methodology has received considerable industrial attention in recent years. As a methodology which is highly responsive to customer's changing requirements, XP has been widely used in Web application developing process. As a key characteristic of XP, Test-Driven Development(TDD) can be used for refactoring the new code and ensuring the quality of the...
Mutation based testing has been considered in many experiments as the most efficacious in terms of revealed faults, but also the most expensive, considering the number of executions. Other problem is that the test data are generally derived from the programs and do not ensure the discovering of faults usually revealed with test data generated from the specification, such as missing paths, which are...
In the software engineering area, has been observed a growing concern to perform experimental studies to evaluate the use of new technologies. However, conducting experimental research is a complex and challenging activity, once it suffers impacts related to human factors. The use of a well defined process for experimental study contributes to the control of the variables involved and their realization...
One of oldest and best-known methods used in constructive testing of smaller programs is the symbolic program execution. It is partly similar to method of simulation of computer function, but differs in aim. One of ways to prove whether given program is written correctly is to execute it symbolically. Aim of this paper is to test ramified program structure using single symbolic set of inputs, in one...
Dataflow testing of programs ensures the execution of data dependencies between locations in the code (1) where variables are assigned values, and (2) where these definitions are used. Such data dependencies are called Def-Use Associations (DUAs). In an aspect-oriented (AO) program, aspects and classes interact in several ways, such as (1) through parameters passed from advised methods in a class...
Current malware detection tools focus largely on malicious code that is injected into target programs by outsiders by exploiting inadvertent vulnerabilities such as failing to guard against a buffer overflow or failure to properly validate a user input in those programs. Hardly any attention is paid to threats arising from software developers, who, with their intimate knowledge of the inner workings...
In the process of testing Component-based software, Oracle problem comes into existence frequently because of the diversity of component running environment and complicated interactions among components. In this paper, we exploit the features of the component-based software and metamorphic testing (MT) to alleviate the issues. The metamorphic class will invoke relevant component to execute test cases...
There are thousands of various software libraries being developed in the modern world - completely new libraries emerge as well as new versions of existing ones regularly appear. Unfortunately, developers of many libraries focus on developing functionality of the library itself but neglect ensuring high quality and backward compatibility of application programming interfaces (APIs) provided by their...
The paper considers the programming technology, which allows partially automate the testing of Internet applications. It allows you to develop a system of testing, as an expert systems. The testing system developing based on the proposed probabilistic-network approach. It allows to implement adaptive testing system, to achieve complete descriptions, improve the reliability of testing and reduce development...
Software systems, which are dynamically composed from plug-and-play components, allow users to adapt an application to the working scenario at hand. While the testing of individual components is well understood, there are no systematic techniques that test if components can be assembled in arbitrary orders. This paper introduces a method and a tool for testing the dynamic composability of component-based...
Test-Driven Development (TDD) has been regarded as a useful practice during the last decade as well in industry as in academia. It has been suggested to have several benefits in software development process. This paper is focused on the reported empirical research on TDD. A systematic literature review was conducted in order to analyze the current empirical evidence. Based on the review data, TDD...
Test-driven development (TDD) - an established approach in business IT software development - enables test case generation based on models early in the development process. Applying TDD and models in automation systems engineering (ASE) can increase testing effectiveness and efficiency. A key question is which models are suitable for ASE application. UML models support software and systems engineering...
