Due to the widespread usage of Graphical User Interfaces (GUIs) in various software applications, GUI testing has gained much importance to software development. In this paper, a model named Activity-Flow Graph is proposed for GUI testing, which can be derived from event-flow graph model, and avoid the problem of generating inapplicable test cases. Experiment results show that the proposed model can...
Test case prioritization technique is an efficient method to improve regression testing activities. It orders a regression test suite to execute the test cases with higher priority earlier than those with lower priority, and the problem is how to optimize the test case ordering according to some criterion. In this paper, we have proposed an algorithm which prioritizes the test cases based on ant colony...
This paper presents a soft-sensing method for predicting the liquid desiccant concentration based on the Extreme learning machine (ELM). The soft-sensing method utilizes a blackbox model including eight inputs variables and one output to predict the concentration in real-time and is a better alternative to manual measurement or expensive and complex sensors. The soft-sensing method is verified with...
Classification of gene expression data to determine subtype of samples is meaningful to research tumors in molecular biology level. It is also an important way to make further treatment plan for the patient. Particle swarm optimization (PSO) is proven to be an ineffective solution for classification and clustering in bioinformatics as it could not give a stable prediction result. In this study, a...
GUI testing is an important and difficult issue. One of the difficulties in GUI testing is that the input domain of a non-trivial GUI application is extremely large or infinite. It is necessary to introduce some coverage criteria to help people select test cases from the input domain of the GUI applications. In this paper, we propose an event handler-based coverage criterion for GUI testing. It requires...
GUI (Graphical User Interface) test cases contain much richer information than the test cases in non-GUI testing. Based on the information, the GUI test profiles can be represented in more forms. In this paper, we study the modeling of the test profiles in GUI testing. Several models of GUI test profiles are proposed. Then we present a methodology of studying the relationship between the test profiles...
XML has become integral to many critical enterprise technologies with its ability to enable data interoperability between applications on different platforms. However, wide adoption of XML is hindered by inefficient parsing methods. In this paper, we present a novel approach for parsing XML in a non-extractive way, encoding node information in 64-bit integers instead of creating node objects during...
