Abstract:
Software tests are fundamental in the reliability and quality of systems, contributing to their positioning in the market. Generating test data is a critical task, as exhaustive testing is costly in time and effort. An adequate design of the test cases, which contemplates a selection of adequate values, can detect a high number of defects. The effectiveness of the test cases is measured according to the number of errors they managed to detect. However, the proposals that address these issues with the use of heuristic algorithms focus on the reduction of generation time and different coverage c

Abstract:
This paper presents an artificial immune system (AIS) based optimized test data generation technique. Software test data generation is a critical activity in software testing. Redundant test data impose an extra cost in form of more testing and increase in efforts. So the generation of effective test data can save time and efforts spent on extra testing of the software. Optimized test data is generated for critical paths of the program. Paths criticality is defined based on the presence of loops and decision.

Abstract:
Software testing is regarded as a pivotal approach to realize a high reliable product. To check for the correctness of results, we require appropriate test cases. UML models are largely used to depict the specifications for software development. Test cases are created independently and based on the sequence of occurrence in the diagrams; they lead to corresponding test paths in the program. In this paper, we have analyzed an activity diagram, consisting of concurrent activities, for generating test paths. The obtained test paths are therefore required to be ranked.

In general multiple paths are covered by multiple runs which is a time consuming task. Now a days, metaheuristic techniques are widely used for path coverage. In order to reduce the time, an efficient method is proposed based on Forest Optimization Algorithm (FOA) with Metamorphic Relations (MRs) that cover multiple paths at a time in one run unlike the traditional search based testing. In the proposed approach, initial test case is generated using FOA, the successive test cases are generated using MRs without undergoing several runs.

One common approach to test sequence generation for structurally testing concurrent programs involves constructing a reachability graph (RG) and selecting a set of paths from the graph to satisfy some coverage criterion. It is often suggested that test sequence generation methods for testing sequential programs based on a control flow graph (CFG) can also be used to select paths from an RG for testing concurrent programs. However, there is a major difference between these two, as the former suffers from a feasibility problem (i.e., some paths in a CFG may not be feasible at run-time) and the l

Abstract:
Based on CP-nets models, an approach of test case generation is proposed for BPEL processes, with which the semantic of BPEL concurrence is well dealt. Firstly, a web service composition which coded in BPEL language is expressed as CP-net models on which depth-first traversal works immediately, and result in sequence test paths obtained. After merging these sequence test paths into program executable units (PEU for short), constraint set of these units is solved and formed into test cases. Finally an application of the approach is illustrated with an example, which more efficiency shown with 7

Abstract:
Permeability is an import character of soil, especially in excavation and tunnelling. Hollow cylindrical apparatus (HCA) is often used to determine soil anisotropy, particularly soil strength and stiffness under different directions of major principal stress, so complex stress paths can be simulated and the corresponding soil properties can be examined. It can also be used to determine the permeability coefficient if a special mode is added, therefore the seepage test can be expected. Owing to no seepage test has been conducted by HCA before, the complete procedure of HCA seepage tests after s

Abstract:
This paper sets out to reveal the relationship between code pattern and infeasible paths and gives advices to the selection of infeasible path detection techniques. Lots of program paths are proved to be infeasible, which leads to imprecision and low efficiency of program analysis. Detection of infeasible paths is required in many areas of software engineering including test coverage analysis, test case generation, and security vulnerability analysis. The immediate cause of path infeasibility is the contradiction of path constraints, whose distribution will affect the performance of different

Abstract:
PurposeFor delivering high-quality software applications, proper testing is required. A software test will function successfully if it can find more software faults. The traditional method of assessing the quality and effectiveness of a test suite is mutation testing. One of the main drawbacks of mutation testing is its computational cost. The research problem of this study is the high computational cost of the mutation test. Reducing the time and cost of the mutation test is the main goal of this study.Design/methodology/approachWith regard to the 80–20 rule, 80% of the faults are found in 20
