Regression testing is a very important part of the program development cycle as it should be executed after feature is integrated or bugs are fixed each time. There are hundreds of test cases in the case library for a little complex product, it is impossible to perform all of the test cases in regression testing every time. Test engineers always select the regression cases by their experience only,...
As a program written in multi-staged language can generate and execute code fragments in execution time, it is hard to predict how many code fragments will be generated in execution time. Therefore, current test coverages are not likely to give right answers when they are apply to a program written in multi-staged language because the program size could not be estimated easily. In this paper, we present...
Since automated fault localization can improve the efficiency of both the testing and debugging process, it is an important technique for the development of reliable software. This paper proposes a novel fault localization approach based on multi-level similarity of execution traces, which is suitable for object-oriented software. It selects useful test cases at class level and computes code suspiciousness...
The increasing importance of embedded software has produced a shift in the testing activities from system testing towards software testing. This has contributed to testing the core system functionality earlier on in the test process. However, this shift has also led to very similar test cases being both described and executed independently at different test levels. We propose reusing multi-level test...
Synchronization between component requirements and implementation centric tests remains a challenge that is usually addressed by requirements reviews with testers and traceability policies. The claim of this work is that linking requirements, their scenario-based formalizations, and software verification provides a promising extension to this approach. Formalized scenarios, for example in the form...
Many applications in the field of scientific computing - such as computational biology, computational linguistics, and others - depend on Machine Learning algorithms to provide important core functionality to support solutions in the particular problem domains. However, it is difficult to test such applications because often there is no "test oracle" to indicate what the correct output should...
Previous studies showed that adaptive random testing is an effective alternative to random testing method, but requires additional overheads to evenly spread test cases. Mirroring was introduced to reduce the overheads of adaptive random testing. This paper is the follow-up work to a previous study on the integration of mirroring and adaptive random testing, namely the mirror adaptive random testing...
Integration testing (IT) plays an important role for validation of the communication between different software components to ensure their optimal cooperation. In this paper we (i) introduce communication sequence graphs (CSG) for integration testing representing the communication between software components on a meta-level, (ii) define coverage criteria based on these graphs, and (iii) give hints...
Increased size and complexity of software requires better methods for different activities in the software development lifecycle. Quality assurance of software is primarily done by means of testing, an activity that faces constraints of both time and resources. Hence, there is need to test effectively within the constraints in order to maximize throughput i.e. rate of fault detection, coverage, etc...
During the software development process, data that has been gained from the testing phase can help developers to predict software reliability more precisely. But the testing stage usually takes more and more effort due to the growing complexity of software. How to build software that can be tested efficiently has become an important topic in addition to enhancing and developing new testing methods...
A major challenge in software testing is adequately testing the effects of changes. The goal of my doctoral research is to provide a precise analysis of the effects of changes in software to effectively automate the testing of changes. In this proposal, I first describe my research problem and discuss related work. Then, I present my approach, research questions, work performed so far, and ongoing...
Code coverage is a common measure for quantitatively assessing the quality of software testing. Code coverage indicates the fraction of code that is actually executed by tests in a test suite. While code coverage has been around since the 60's there has been little work on how to effectively analyze code coverage data measured in system tests. Raw data of this magnitude, containing millions of data...
The importance of good software testing is often reported. Traditionally, acceptance testing is the last stage of the testing process before release to the customer. Unfortunately, it is not always appropriate to wait so long for customer feedback. Emerging agile methods recognise this and promote close interaction between the customer and developers for early acceptance testing, often before implementation...
Search based testing approaches are efficient in test data generation; however they are likely to perform poorly when applied to programs with state variables. The problem arises when the target function includes guards that reference some of the program state variables whose values depend on previous function calls. Thus, merely considering the target function to derive test data is not sufficient...
Search based software testing has emerged in recent years as an important research area within automated software test data generation. The general approach of couching the satisfaction of test goals as numerical optimisation problems has been applied to a variety of problems such as satisfying structural coverage criteria, specification falsification, exception generation, breaking unit pre-conditions...
Testing of database applications is crucial for ensuring high software quality as undetected faults can result in unrecoverable data corruption.Conventionally, database application testing is based upon whether or not the application can perform a set of predefined functions. While it is useful to achieve a basic degree of quality by considering the application to be a black box in the testing process,...
Web services have become popular in the modern infrastructure of the World Wide Web. They aim to provide automatic discovery, selection, and invocation of required applications (services) across the internet. However, the quality assurance aspects of Web services remain a challenge. Recently, the semantic Web has been introduced as an emerging technology which emphasizes presenting the meaning of...
This paper tackles the use of software testing techniques for Web-Application non-functional requirements. It also shows load and performance testing application in a case study. At the end, a successful new approach for the navigability testing for Web-Applications is proposed.
This paper presents a method, control-flow interval iteration in presence of interprocedural side-effect analysis, to improve test precision in software testing based on defect patterns, then an exact interval computation can be used in defect test algorithm of DTS. Our experiment shows that the DTS, using this method, can reduce the false positive rate and drop defect rate effectively.
The Multi-Attribute Global Inference of Quality (MAGIQ) technique is a simple way to assign a single measure of overall quality to each of a set of similar software systems. Software testing activities can produce a wide range of useful information such as bug counts, performance metrics, and mean time to failure data. However, techniques to aggregate quality and testing metrics into a single quality...
